This paper presents the active power flow control in the transmission line by use of voltage source inverter in closed loop. A two transmission line model is built in the MATLAB Simulink software and the active power flow in one of the line is controlled by injection of voltage into the transmission line through an isolation transformer from the voltage source inverter. A unipolar pulse width modulation technique is used to generate the PWM pulses to the voltage source inverter. The phase angle of the reference sinusoidal signal is controlled to control the angle at which voltage is injected into the line so that desired active power flow is achieved. © 2018 IEEE.

The main objective of Automatic Voltage Regulator (AVR) is to maintain the terminal voltage through controlling the excitation. Automatic Load Frequency Control (ALFC) plays significant role in maintaining the frequency through controlling the mechanical power input to match the varying load requirements. In this paper, the laboratory model of AVR along with ALFC is developed. The proposed AVR and ALFC system based on laboratory model gives an added advantage over the mathematical model due to its materialistic approach. AVR senses the terminal voltage of an alternator and compares with the reference voltage and generates error signal which intern adjusts the field current by using DC-DC Buck chopper. ALFC senses the speed ofthe alternator and compares it with the reference speed and generates error signal which intern adjusts the mechanical power input to an alternator by using DC-DC Buck chopper connected to the armature terminal of the DC-motor. The entire setup is simulated in Matlab@ simulink. The proposed laboratory model based AVR and ALFC system is tested for various loading conditions to validate its effectiveness. © 2018 IEEE.

Deregulation creates competitive market with GENCOs and DISCOs as the market players. The GENCO offers and DISCO bids are submitted to market operator who clears the market with the aim to maximize social welfare. The power trading is done in an open access between in-merit GENCOs and DISCO. The allotted power demand of each in-merit DISCO is met by in-merit GENCOs that generates contracted power. Thus, GENCOs share a portion of the power demand of each DISCO. The contribution of each GENCO to meet power demand of a DISCO is represented in terms of area participation matrix. During contract violation, willing GENCOs shares the un-contracted power demand based on economic participation factor. Thus, GENCOs generate the contracted (during contracted condition) and un-contracted power (during violation) based on area participation factors and economic participation factors respectively. This is achieved with the help of automatic generation control. This paper assumes a two area system with different market conditions and develops a generalized mathematical expression to calculate these factors based on the allotted in-merit GENCO power and available willing GENCO power. These factors are then incorporated in the mathematical model of two area system under deregulated environment. The performance of the developed model is tested under tie line bias control strategy to check whether the GENCOs and TRANSCO power is based on the participation factors.

Congestion management is controlling the power flow in transmission line within the steady state stability limit. In deregulated power system, both economics and system security should be considered while managing the transmission line congestion. Price area congestion management technique is the one that not only relieves transmission line congestion but also provides maximum benefit to the stakeholders. The price area concept adopts different pricing for each area rather than fixing same price for all the areas. Different area pricing without congestion is achieved by increasing the price in deficit area and decreasing the price in surplus area. In this paper, control strategy based on price area congestion management for a three area system is developed. The control strategy is tested on a three area system operating in all possible combinations of contract. The test results prove that the control strategy based on price area concept relieves congestion without affecting the net surplus of the generation and distribution companies.

This paper explains the development of laboratory model to teach Surge Impedance Loading to the undergraduate students. Simulation software used for teaching power systems fails to give physical sense to the students. The scaled down model of transmission line is developed at the Electrical Engineering development of Amrita school of Engineering, Coimbatore. The flat voltage profile is observed in the line when the line is loaded to Surge Impedance Loading. Further the Surge Impedance Loading and phase shift are studied during series and shunt compensation. Shunt capacitor compensation improves only Surge Impedance Loading but increases the phase shift. Series capacitor compensation improves Surge Impedance Loading and also stability by decreasing the phase shift. © 2016 IEEE.

To teach and demonstrate the Power System Stability aspects to the undergraduate students, a laboratory model has been developed. Computer based simulation software's are used to teach different aspects of power system by most of the Institutions. These simulation studies often do not demonstrate the physical sense of power system behavior to students. Moreover, making the students to visualize the effect of instability is a very big challenge faced by the teaching community. This paper describes the experimental set up built in the Electrical Engineering Department of Amrita School of Engineering, Coimbatore, consisting of an alternator connected to infinite bus through parallel transmission lines. In this experimental setup, the generator is brought to instability by changing the operating conditions. Further, the oscillation is controlled and brought back to stability by controlling the excitation and line reactance. This gives the clear idea about stability and its enhancement to the students.

ABSTRACTThis paper discusses about self-regulating the reference flux in induction motor (IM) direct torque control (DTC) drive by fuzzy logic. Self-regulation is improved by using “Artificial Neural Network (ANN)” and “Adaptive Network Based Fuzzy Inference System (ANFIS)” based reference flux estimators. Furthermore, PI speed controller is investigated to develop the performance of the drive. Two different PI speed controller tuning strategies, manual and Fuzzy Gain Scheduling (FGS), are compared for load torque disturbance. The results clearly show that the modified DTC of IM with “ANFIS-based reference flux estimator and FGS-tuned PI speed controller” is most suitable for torque ripple reduction and speed control.

The article focuses towards the development of an optimal secondary controller which could adapt with the varying system conditions to maintain the frequency and tie-line power flow variations within the nominal value. For the analysis, a two area multi source system consisting of thermal, hydro and nuclear system in one area is interconnected with another area comprising of thermal and hydro system via parallel AC-DC links. On subjection to unit step load change in demand, the impact on frequency and tie-line power flow variations in multi source multi area is observed under MATLAB/Simulink environment. The fine tuning of frequency and tie-line power flow variations is achieved with the help of secondary controller. Optimal secondary Proportional Integral (PI) controller is chosen based on Zeigler Nichols’ (ZN), Genetic Algorithm (GA), Fuzzy Gain Scheduling (FGS) and Adaptive Neuro-Fuzzy Inference System (ANFIS) tuning techniques. On subjection to different load variations at different intervals of time, ANFIS tuned PI controller has retained the frequency and tie-line power variations for a robust multi source multi area system interconnected via parallel AC-DC links in a much faster way to its nominal values than other methods. The performance of the controller is evaluated based on performance indices.

Load following is one of the major components which ensures the secured operation of power systems. The complexity of the load following control strategy increases when the system operates under deregulated environment. A load following system has to control not only the frequency and tie line power but also the power generation as per the contract. The contract is decided by any one of the three market model namely single buyer, bilateral and poolco model. This paper develops load following system operating under different models. The generalized factors based on which the load following satisfies the scheduled and violated power are computed for all market models. Finally the system is simulated under different models with contract violation to justify the performance of load follower. The developed generalized market participation factors and violation participation factors make the load follower to yield desired secured power system.

It is necessary to operate the power system in interconnected mode with the development of renewable and non-renewable energy sources and increase in load demand. Bio fueled gas turbine plants as a form of renewable source can be operated along with other sources of generation but have to be properly connected and controlled to provide better performance when sharing a common load. This paper deals with load frequency control of single area multi source system consisting of hydro, thermal and gas turbine. When subjected to load change, the speed governor helps in controlling the frequency to its nominal value but secondary controller is required for fine tuning of frequency. Proportional integral (PI) controller is used in this work. Ziegler Nichols’ (ZN), Genetic Algorithm (GA) and Fuzzy Gain Scheduling (FGS) methods have been used for optimal tuning of secondary controller. FGS tuned secondary controller found to yield better performance.

The article proposes optimal secondary controller for combined Load Frequency Control (LFC) and Automatic Voltage Regulation (AVR) of multi source multi area system using simulated annealing technique. When subjected to load disturbance, frequency, tie-line power and voltage fluctuations results higher oscillations. Speed governor of the system helps to match generation with the demand. But, fine tuning of frequency, tie-line power and voltage when subjected to load disturbance in multi source multi area system is achieved by secondary Proportional Integral Derivative (PID) controller. As a conventional benchmark \{PID\} controller is tuned using Zeigler Nichol’s (ZN) method and further optimized using Simulated Annealing (SA) technique.

In this paper, the transfer function model of heavy duty gas turbine has been developed for doing load frequency control studies. Based on the large signal model of Rowen, small signal model has been developed. This model is much suitable for doing Automatic Generation Control. Proportional integral and derivative secondary controller has been developed for both the small and large signal models to improve the system response. Ziegler Nichols’ method, Simulated Annealing and Fuzzy Gain Scheduling have been used for tuning the secondary controller. Ziegler Nichols’ method is used as conventional tuning, whereas Simulated Annealing is a search based tuning and Fuzzy Gain Scheduling is adaptive. It is found that Simulated Annealing tuned Proportional Integral Derivative Controller yields better response than other two controllers in both large signal and small signal model of heavy duty gas turbine plant.

Abstract This paper modifies the traditional Automatic Generation Control scheme based on tie line bias control. The proposed scheme takes the GENCO reserve and TRANSCO corridor into account to permit the unscheduled power transactions. The suggested control scheme is demonstrated on a deregulated multi source multi area system. Control strategies for the deregulated system are developed to manage the contract violation for all possible combinations of GENCO reserve and TRANSCO corridor. The results obtained from the proposed scheme are found to be effective in regulating frequency and power exchange between the areas during contract violation.

The deregulation of power industry is restructuring of rules of monopoly, hence bringing in more private players to sell or buy the electricity as a commodity. The power and price values are bid by the respective generation companies (GENCO’s) and distribution companies (DISCOM’s) through the electronic mode. There are various complex computing methods for determining the optimum price among which the power exchange curve method is discussed herewith. By plotting demand and supplier power characteristics curves, the intersection point, MCP (Market clearing price) can be determined. MCP calculation is one of the most important functions of a power pool operator. Its main objective is to maximize the Global welfare function where the generating companies and the consumers are benefited and unbiased. The MCP is calculated using MATLAB software and the winning bidders of the current market are found. The power obtained for the winning supplier then undergoes optimum scheduling for generation optimization namely, supply side management. The power optimization includes Unit Commitment (UC) and selected units to be committed undergo Economic Load Dispatch (ELD). For practical implacability, the supply side power management is implemented using Programmable Logic Controller (PLC) communicated through the Supervisory Control and Data Acquisition (SCADA) system.

In this paper, self-regulation of stator flux in Direct Torque Control (DTC) of Induction Motor Drive is achieved. Direct torque control is based on torque, flux hysteresis controllers and the stator flux angle. Based on hysteresis controllers and stator flux angle a look up table is constructed. In DTC Stator flux is divided as six sectors. Due to look up table uneven voltage vectors are distributed to control the stator flux and torque in a DTC induction machine. The stator flux magnitude droops at every switching sector transition, particularly when the machine is running at low speed with a heavy load. To overcome this sectors are slightly wavered for some angle. The performance of the controllers are investigated for load torque disturbance using Performance Indices ISE, ITAE and ITSE. The results clearly shows sector oscillation improves the performance to further reduce the torque ripple saw tooth sector wavering is used. © Research India Publications.

Multi source systems involve combined operation of two or more generating units with renewable or non-renewable sources. Multi area system is the integrated operation of different groups of multisource units sharing local electric loads between them. These systems will be the future of power systems extended to remote consumers for grid connected operation and control. A gas turbine plant operated with bio mass fuel will be one such renewable source that can be interconnected to other sources like hydro and thermal for sharing a common load. This paper deals with the load frequency control of these multisource multi area systems operating under tie-line bias control strategy. A set of suitable secondary controllers are tuned for the better performance. It compares the performance of classic Ziegler Nichols (ZN) tuned controller with the Genetic Algorithm (GA) tuned secondary controller. GA provides a better controller for the interconnected operation of the thermal, hydro and gas turbine plants. © Research India Publications.

Conventionally, Automatic Generation Control (AGC) is carried out by primary governor control and secondary Proportional-Integral (PI) controller. PI controller helps to damp out tie-line power and frequency oscillations when subjected to unit step load disturbance. Ziegler Nichols' (ZN) method is used in tuning the gains of conventional PI controller and VSS controller. Optimal switching of VSS controller is carried out by the performance indices. UPFC based damping controller helps to stabilize the tie-line power oscillations of power system. The simulation indicates reduced frequency and tieline power transient with much faster settling time is obtained by using UPFC along with secondary VSS controller. © JES 2012.

In this paper, the Load Frequency Control (LFC) is enhanced with optimal gains of the Variable Structure System (VSS) Controller tuned using Genetic Algorithm (GA). For analysis, two-area thermal and hydrothermal power plants are considered in this paper. Conventionally, Proportional Integral Derivative (PID) controller is used to control frequency and tie-line power deviations. To improve the PID control action during transient and steady state period, the PID controller is replaced by VSS Controller. The gains of the controllers are tuned using Zeigler Nichols' (ZN) and further with GA optimization technique. The performance of the controller is judged using Integral Time Absolute Error (ITAE) method. On analysis, it is observed that frequency and tie-line power deviations are improved using GA tuned VSS controller. © 2012 Praise Worthy Prize S.r.l. - All right reserved.

Finally, Variable Structure Fuzzy Gain Scheduling Controller is developed by integrating Fuzzy in Variable Structure System Controller resulting better controller action during transient and steady state period. The performance of these controllers is judged using Integral Time Absolute Error and Integral Time Squared Error techniques. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

This paper focuses on controlling the hydrothermal plant using Variable Structure System (VSS) controller and Superconducting Magnetic Energy Storage (SMES) unit. The Automatic Generation Control (AGC) of hydrothermal plants is conventionally done by Proportional-Integral (PI) controller, which yields desired response too. For, further improvement of transient and steady state response, the conventional PI controller is replaced by Variable Structure System (VSS) controller. Ziegler Nichols’ (ZN) method is used in tuning the gains of conventional PI controller and VSS controller. The system response in terms of transient and steady state is much improved while using VSS controller than conventional PI controller. The Superconducting Magnetic Energy Storage (SMES) unit being a frequency stabilizer which helps to damp out frequency oscillations much faster, is used along with the Variable Structure System (VSS) controller for controlling the hydrothermal power plant. The simulation response shows that the hydrothermal system with Variable Structure System (VSS) controller and Superconducting Magnetic Energy Storage (SMES) unit exhibits better frequency and tie line power performance.

Gas turbine generators, normally used in isolated operation, require an effective control and design for their parallel operation. Otherwise, the load variations and set-point variations may cause severe stability problems. Soft computing techniques, such as genetic algorithms, artificial neural networks, and fuzzy logic, have been utilized for developing a controller for a gas turbine plant. The proportional-integral-derivative controller is used to control the gas turbine plant because of its versatility, high reliability, and ease of operation. For better performance, the gains of the proportional-integral-derivative controller have been tuned using the Ziegler–Nichols method and genetic algorithm. The artificial neural network and fuzzy controllers are developed, and the performance is compared with the conventional proportional-integral-derivative controller. The results show that the optimal time domain performance of the system can be achieved with the fuzzy logic controller. The fuzzy logic controller removes the steady-state error in less time with no overshoot and oscillation.

Gas turbine plants are used for isolated and standalone operations. They are mainly used in oil fields, desert areas, off shore installations and bio gas plants. An effective control strategy is required to keep the system stable under disturbance. The Transfer function model of heavy duty gas turbine has been developed by Rowen [1] based upon his field experience and the tests he conducted in the gas turbine plants. This model has been used in many works such as, the dynamic analysis of combined cycle plant [2], twin shaft gas turbine model [3], combustion turbine model [4] and even in micro turbine power generation [5]. The transfer function simplification has been validated [6]. The droop governor is found to be an appropriate one [7]. The droop setting value and rotor time constant have been optimized [8]. After tuning the parameters, the response of the gas turbine plant shows steady state error. To improve the transient and steady state response, PID controller is required. The parameters of PID controller have been tuned using ZN method and the steady state error is removed. In this paper, Artificial Neural Network is used for control which uses backpropagation algorithm for training. The trained ANN brings back the system to steady state. It is found that ANN controller yields a better response than the conventional PID controller.

IEEE, Department of Electrical and Electronics Engineering, Amrita School of Engineering, Bengaluru , p. 337, 2016.[Abstract]


Restructured power system creates a competitive environment where different players like generating and distribution companies enter into auction or negotiations. Under bilateral model, GENCOs schedule power based on the contracts made with the DISCOs. Moreover, the transmission companies are made to operate at the contracted value. Ensuring system stability and reliability is a big challenge under restructured power system. The paper proposes a control strategy for load frequency control in a three area deregulated power system, with the objective to regulate the system frequency and TRANSCO power variation. The effectiveness of the control strategy is tested during contract violations.

IEEE, Department of Electrical and Electronics Engineering, Amrita School of Engineering, Bengaluru , p. 91, 2016.[Abstract]


In this paper, the real power flow control in a transmission line is done by using active series compensation technique. The active compensator varies the power angle in the line using a power electronic device. The power angle is varied by injecting voltage to the line that is in phase shift with line voltage. This varies the real power flow in transmission line. Using this technique, the rerouting of power flow can be achieved to satisfy the inequality constraints. By controlling the injected voltage magnitude and the phase angle, accurate power flow control can be achieved. In this paper, an embedded system based active series compensator is developed and the power flow control in a two bus system is achieved effectively.

IEEE, Department of Electrical and Electronics Engineering, Amrita School of Engineering, Bengaluru , p. 88, 2016.[Abstract]


Interconnected transmission system provides a wide scope for power sharing thereby avoiding chances of overloading in transmission lines. But this can be achieved only with proper control on the transmission network. The aim of this work is to improve the real power flow in the transmission lines by varying the transmission line reactance. Real power flow can be improved by series compensation using a Static Series Compensator (SSC). A fixed capacitor connected in series with the transmission line can effectively reduce the transmission line reactance thereby improving real power flow. But series compensation using a capacitor can provide only fixed compensation, a smooth variation in reactance cannot be achieved. In this paper a Thyristor Controlled Static Series Compensator (TCSC) is used for controlling the power flow in the transmission line. Open loop control of TCSC by varying the firing angle is simulated using MATLAB. A hardware implementation of TCSC to analyse the power flow control is deployed in a 2-bus system.
