S. Vishnupriya and Dr. P. Kanakasabapathy, “Fault Ride Through for a DC ring bus microgrid”, in 2016 International Conference on Energy Efficient Technologies for Sustainability, ICEETS 2016, 2016, pp. 11-16.[Abstract]


DC microgrid is gaining more prominence due to the development of renewable resources that generate DC output and also due to the increasing use of DC in end-user equipments. Also with DC system, connection of backup energy storage and small size generation is easier to realize. For any system, disconnecting a part of the system during temporary faults is uneconomical and might lead to network instabilities. To overcome this, the system must possess Fault Ride Through (FRT) capability. FRT is the ability of the system to remain connected during faults. In this paper, FRT for DC ring bus micro-grid system is achieved for temporary faults. After the occurrence of a fault, the system will ride through the fault until a predefined time period is exceeded. When the predefined time period is exceeded, the system classifies the fault as a permanent fault and the system is isolated. The FRT is achieved by supplying a limited amount of current to the fault using Fault Current Limiters (FCL) working with the proposed algorithm. More »»

Maximum power point tracking is a method to trap maximum available power from a solar panel. Many algorithms have been developed based on the characteristics of solar panel in order to utilize maximum available power. But these algorithms do not consider local maxima and minima in the solar panel characteristics caused due to shading. In this paper an enhanced version of Perturb and Observe maximum power point tracking algorithm is explained which also considers local maxima and minima caused by shading and makes the solar panel to work at its peak maxima. This helps in improving the overall efficiency of the system. Algorithm is implemented on 50W solar panel using ATMega 8 microcontroller and a boost converter. More »»

The main challenge for DC distribution system is the lack of a good protection system. In this paper a ring type DC microgrid is considered. Upon fault in the grid, the existing system shut down the entire grid. A new protection algorithm is proposed which isolates only the faulted section, without the entire grid shut down. The algorithm senses the fault using differential current and then current derivative is taken for segment isolation. The proposed algorithm is verified using Simulink/MATLAB. More »»

R. Sarath and Dr. P. Kanakasabapathy, “Hybrid converter based on ĆUK topology to supply both AC and DC loads”, in Proceedings of IEEE International Conference on Technological Advancements in Power and Energy, TAP Energy 2015, Kollam, India, 2015, pp. 387-392.[Abstract]


Residential power systems are getting modernized due to the increased penetration of power electronic systems. Modern nanogrid architectures usually serve to interface both DC as well as AC loads with different kinds of energy resources. This paper proposes a Ćuk-derived hybrid converter (Ćuk-DHC) procured from the conventional Ćuk topology, where the single power electronic switch is replaced with a voltage source inverter bridge network. The resulting converter employs lesser number of switches to produce DC and AC outputs simultaneously. A major advantage of this hybrid converter is that it has immanent shoot-through protection in the inverter stage making it reliable for modern compact smart residential power systems. Moreover, being a derived converter, it holds the advantages that a conventional Ćuk converter possesses. Operating modes and the steady state analysis of the proposed converter have been studied in this paper. A modified unipolar sine pulse width modulation (PWM) technique is used as the control strategy for the operation of the hybrid converter. The characteristics and operation of the proposed converter has been validated through simulation. For improving the output gain factor, a switched inductor cell based modification has been imposed on the hybrid converter to upgrade both dc as well as ac gains and the same has been affirmed via simulation. © 2015 IEEE.

Conference Paper

Dr. P. Kanakasabapathy and Mohan, M., “Digital protection scheme for microgrids using wavelet transform”, in IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC 2015), Singapore, 2015.[Abstract]


The dynamic nature of microgrids compromises the efficiency and accuracy of the conventional power system protection strategies. This paper proposes a novel digital and microprocessor based protection scheme for microgrids using signal processing techniques. Digital relays are employed with fault detection algorithm. Fault detection is done based on a relatively new signal processing technique called Wavelet Transform (WT). The dq0 decomposition technique is used to reduce the computation time of the relay algorithm. The WT is used to decompose dq0 axis components of current and voltage signals to obtain high-frequency details of the same which is used to detect high frequency transient disturbances due to the fault. Fault location and isolation is done using power high-frequency details, which are calculated as the product of the high-frequency details of current and voltage. A threshold is defined for the cumulative sum of the power high-frequency details, deviation from which is observed only on the faulty bus, thus, triggering a tripping action. The system has been tested for various faults within the microgrid for different operating modes. Software simulation and hardware testing results were obtained for the proposed method and it has been inferred that the proposed protection scheme detects and isolates faults in a fast and accurate manner.

Demand for electricity is ever increasing. In order to balance the growing needs, distributed generation (DG) can help to a large extent. Micro-grids (MG), mainly inverter based, are gaining more and more importance as they can accommodate various types of DGs effectively and for their superior power quality. A MG can be operated in two modes, grid connected and islanded mode. Each mode has its own control strategy. In this paper a control strategy for inverter based MG which can ensure stability and proper power sharing among the inverters, in islanded mode, is proposed. In a MG, the output impedance of inverter can have much impact on load sharing of inverters. The proposed control scheme uses second order general integrator in conjunction with indirect operation of droop method, to enhance the stability and power sharing in MG. © 2014 IEEE.

This paper presents the analysis and development of a new digital differential protection scheme for three phase power transformers. The proposed scheme extracts the high frequency information hidden in the differential as well as the fault currents to identify internal faults. The commonly used signal processing tool, Wavelet Transform which has an impressive reputation in this field fails to represent objects with highly anisotropic elements such as lines or edges efficiently due to the limitations in directional and scaling elements. Proposed scheme applies curvelet transform to the differential current to extract the required information and identify the faults. Extensive simulation using MATLAB Simulink has been done to validate the method and the results are validated by comparing with other schemes. © 2013 IEEE.

This paper develops optimal bidding strategies for a pumped storage plant in competitive electricity market. In a restructured environment, when compared to a simple hydro electric generator, the profit of the pumped storage plant is maximized by operating it as a generator when market clearing price is high and as a pump when price is low. Based on forecasted hourly market clearing price curves, a multistage looping algorithm to maximize the profit of a pumped storage plant is developed considering both the spinning and non-spinning reserve bids and meeting the technical operating constraints. The proposed model is adaptive for the nonlinear three-dimensional relationship between the power produced, the energy stored, and the head of the associated reservoir. Different operating cycles for the storage plant are considered and simulation results are reported and analyzed.

This paper develops optimal bidding strategy for operating multi-unit pumped storage power plant in day-ahead electricity market. Based on forecasted hourly market clearing price, a multistage looping algorithm to maximize the profit of multi-unit pumped storage plant is developed considering both spinning and non-spinning reserve bids and meeting the technical operating constraints. The proposed model is adaptive for the nonlinear three-dimensional relationship between the power produced, the energy stored, and the head of the associated reservoir.

The discrete characteristic of a pumped storage plant is modeled using tri-state coding technique and genetics based mutation operation is used for faster convergence in getting global optimum. The proposed approaches are applied with an actual utility consisting of four units. Experimental results for different operating cycles of the storage plant indicate the attractive properties of the ETPSO approach in a practical application, namely, a highly optimal solution and robust convergence behaviour.

The IEEE 802.16 broadband wireless access system (BWA) offers the advantage of fast deployment and cost-effective solution to the last-mile wireless connection problem. For mass adoption and large scale deployment of BWA system, it must support quality of service (QoS) for real-time and high bandwidth applications. The IEEE 802.16 standard defines the QoS signaling framework and various types of service flows, but the actual QoS mechanisms such as packet scheduling algorithms for these service flows are unspecified in the standard. We evaluate the performance of the various packet scheduling algorithms and also propose an efficient scheduling algorithm based on the transmission opportunity given to each station to support QoS in IEEE 802.16 standard. We show that the proposed scheduler provides improved performance in terms of mean delay and average system throughput compared to the other scheduling schemes through extensive simulations.

Pumped storage hydroelectric plants are attractive in competitive electricity markets because of their operational flexibility and ability to provide rapid response to change in spot price of electricity. Operating pumped storage plant affects the consumer and producer surplus of the individual market and hence leads to significant changes in energy prices. This paper investigates the impact of pumped storage energy trading on the social welfare of electricity market. A theoretical analysis and intuitive explanation are presented and numerical case study is also illustrated to validate the analytical results developed. Energy trading by pumped storage increases the overall social welfare of the market, when both storing and releasing energy. Further, the implications of pumped storage energy trade are producers benefit more during storage and consumers benefit more during release of stored energy.

The reliability and stability of a power system depends to a great extent on the efficiency of busbar protection scheme. The proposed protection scheme makes use of curvelet transform based analysis. Curvelet transform overcomes the weakness of wavelets in higher dimensions and will better capture the curve singularities and hyper plane singularities of high dimensional signals. The detail and fine coefficients of curvelets are strongly orientation sensitive, which is a useful property for detecting curves in signals. The proposed algorithm was tested using the busbar modeled in Simulink and simulating various fault conditions. The signal analysis was done by using wrapping based fast discrete curvelet transform. Results presented in this paper showed the capability of implementing a busbar protection
