Harmonic contents present in power network have adversely affected the power quality and this reduces the stability of the system. In this paper, active filter-based compensation has been developed using the PV source. A nonlinear BLDC load is considered which injects more harmonic current in the system whereby increasing the total harmonic distortions (THD). This THD value needs to be maintained below the permissible limit by properly controlling the shunt active power filter (SAPF) to get effective compensation. In this work, synchronous reference frame (SRF) theory is used to produce the compensating current required for canceling the harmonic content produced by the BLDC load and for compensating the reactive power. The energy to active filter is obtained from PV array and the intermediate DC-to-DC converter stage is used to smoothen the operation of BLDC motor drive. The complete system is modeled and simulated in MATLAB Simulink. From the simulation analysis, it shows that the reduction of THD (%) is within the limits and VAR compensation is achieved thereby improving the power factor.

Most of the modern industry drives uses an induction motor as the main drive system. The properties like compact size, low cost, and wide range of speed control makes induction motor a universally acceptable electromechanical device. Due to the wide usage, they are prone to different faults. The presence of faults affects the operation of the Induction motor by reducing its efficiency. If these faults are not diagnosed at the proper time, they can lead to the shutdown of the entire system under operation. Thus there is a constant need for the reliable and safe operation of Induction motors. Condition monitoring is required through which presence of various faults occurring in induction motor can be diagnosed beforehand and necessary precautions and preventive works can be performed. The proposed method deals with the fault diagnosis and detection through continuous monitoring based on Motor Current Signature Analysis (MCSA). Among the various methods used for fault diagnosis, Soft Computing techniques form a promising option. The proposed algorithm is implemented using Fuzzy Logic soft computing technique. The paper discusses the results obtained by simulating and detecting various faults in induction motor using Fuzzy logic, in C#. Experimental results have verified the effectiveness of the proposed method.

The battery management system is becoming important due to the extending utilization of embedded devices equipped with rechargeable batteries that have higher power and energy density. Battery Energy Storage System (BESS) is used to store electrical energy on a large scale in power grid and electric vehicles. Lithium ion (Li-ion) battery is currently the most widely used form of energy storage. Parameters like State of Charge (SoC), ambient temperature, state of health etc determines the lifespan of a battery. SoC is a key factor which gives the rate of charge in the battery with respect to its total capacity. The direct measurement of SoC is not possible but it can be estimated by different methods. Coulomb counting method is the most widely used method to estimate SoC but the Coulomb-counting algorithm experiences aggregate mistakes due to the initial SOC. Coulomb counting and fuzzy logic method is combined here to estimate the SoC. Here a fuzzy logic method is used along with the CCM method to get optimal SoC value of the Li-ion battery. Simulation is done for the charging and discharging of Li-ion battery and the results are analyzed. Reliable operation and prolonged lifespan can be achieved through this technique. The new technique will help to establish more accurate and reliable results. Accurate SoC estimation save the battery from being deeply discharged and over-charged. Matlab simulink is the simulation tool used to establish the results.

Energy Conservation and management is gaining popularity in research area due to the increase in energy demand. It also plays a vital role in industrial/commercial/domestic/power sectors for reducing the carbon emission, the energy bill. Thus, increase in conservation would change the economy of the world energy crisis. To conserve energy, it is very important to have a better monitoring and identification system. The existing monitoring technique has conventional energy meter or smart energy meter that gives total energy consumption only. To enhance a better quality of services in existing monitoring technique, there is a need to monitor energy consumption of individual appliances and hence one meter/sensor for each appliance are necessary. Due to more sensors and its associated installation cost, this technique is not a cost effective in nature. To overcome Non-intrusive Load monitoring technique was introduced to disaggregate the total energy consumption from a single meter using Machine learning disaggregation algorithm. Thus, to identify the appliances malfunctioning Non-intrusive load monitoring (NILM) technique can be used as a Real time Monitoring technique. In this paper, it is proposed to use single energy meter for the set of appliances to monitor the status of the individual appliances. Non-intrusive Load Monitoring technique using machine learning algorithms has been discussed for appliances identification and monitoring for energy conservation. The MATLAB/Simulink Software has been used for designing and mathematical modeling of each appliance. The NILM technique mainly involves the three stages via; Data acquisition, feature extraction and training of data under different classification algorithm for appliance identification. Data acquisition used for acquiring the voltage and current from a single phase system. Using the features extracted like active, reactive power the different load patterns of individual appliances can be studied. Training of data under DT and K-NN which are supervised learning techniques are used as disaggregation algorithm. Moreover, the algorithms are compared using the Confusion matrix and ROC curve for the prediction of accuracy. The result shows that the K-NN algorithm is having a better accuracy of performance compared with DT algorithm.

Photovoltaic (PV) systems are gaining importance in the present electrical distribution systems due to government policies and initiatives, hence the power production cost is also decreasing day by day. This paper focuses on the impacts of rooftop solar PV systems on secondary distribution system, which is rated to 30kW grid tied solar power plant. While studying the impacts of rooftop solar PV system on secondary distribution system, it is necessary to study power quality issues arising due to the integration of rooftop solar PV system and also possible solution to mitigate power quality problems. The study has been done on three different cases, first with the 30kW grid tied solar PV system alone, then 30kw grid tied solar PV system with 5 rooftop PV added to the system, finally 30kw grid tied PV system with 5 rooftop PV system with and without adding hybrid filters to the system and the results are obtained using MATLAB which shows the reduction in harmonics after the addition of hybrid filters to the system. Also, an advanced net metering is modelled in this paper which enforces the consumers to install harmonic filters to bring down the THD within limits, thus the consumer will have to pay penalty charges if the THD value exceeds the permissible levels.

Mid-field wireless power transfer (MF-WPT) is a scheme developed for transcutaneous power transfer to microimplants kept deep inside the body in GHz frequency.With deep seated implants, the possible locations available for application increases to almost the entire body. But, this advantage of applicability is severely limited as the power delivered to the micro implants by MF-WPT is very low -in the range of few 100W. Yet, the mid-field operations have higher efficiency in miniaturized weakly coupled coil implants compared to traditional near-field system. So, with improvement in certain aspects, MF-WPT is expected to play a vital role in biomedical field. For the same reason this paper focuses on analyses of literature available in various aspects of MF-WPT, its challenges, drawbacks and future scope of the scheme in medical field.

Industries that are situated far away from grid access, industries which cannot tolerate frequent power outages and power quality issues would produce a portion or whole of their demand using fossil fuel based technologies in their site. Fossil fuel based technologies exhibit disadvantages like high operating cost, fluctuations of t he p rice of f uel, g reenhouse g as emission etc. Therefore, the use of renewable resources for electricity generation is gaining awareness. Inverters are predominantly used in such systems. Most commonly used the inverter in these applications is the three phase three leg voltage source inverter(VSI). When supplying unbalanced loads and nonlinear loads, the inverter performs with numerous problems such as poor dc link utilization, lower efficiency, high common mode volt-age(CMV) and adverse electromagnetic interference(EMI) effects.

Liquid sloshing has been a challenging problem in different fields including launch vehicles and long range missiles applications. The coupled-slosh vehicle dynamics constitutes a highly non-linear second order under actuated system. The system is highly non-linear system, therefore controlling of slosh is highly complex. This paper presents a novel way of designing a Sliding Mode Controller (SMC) using non-linear sliding surface is used for slosh control in a container. Modeling of slosh dynamics is highly complex and nonlinear, the most commonly used equivalent mechanical model for lateral slosh dynamics is simple pendulum model. For linearizing the system, Partial Feedback Linearization technique has been used. In various literature SMC has been used as controller, the main issue of using SMC is chattering effect. For reducing the chattering effect in the control efforts the Boundary Layer Design technique is developed. Hence the proposed controller will provide better closed loop performance compared with conventional SMC (SMC with linear sliding surface). The proposed system is modeled and simulated using Matlab/Simulink to prove the effectiveness of SMC with nonlinear sliding surface compared with linear sliding surface.

Pulse width-modulated (PWM) inverters are used more and more to operate electrical machines and to interface renewable energy systems with the utility grid. However, there are abundant high-frequency harmonics in the output voltage of a PWM inverter, which increase the iron losses and result in derating of the machine or transformer connected to them. Predicting the iron losses caused by the PWM supply is critical for the design of electrical machines and transformers operated by PWM inverters. These losses are primarily attributed to eddy-current loss caused by the PWM supply. In this paper, after analyzing the harmonic components of PWM inverter voltage, the effects of different parameters of PWM switching on the eddy-current loss has been derived. The iron loss modelled with the proposed analytical methods on a three-phase transformer and is compared with the results of finite element analysis. This paper presents detailed equations for the prediction of iron loss. These equations can be directly applied in the design and control of PWM converters and electric motors to improve energy efficiency and reduction in total harmonic distortion in electrical machines and transformers operated by PWM converters.

Distribution of quality power to the consumers is one of the greatest challenges in power industry. In practice, the presence of various nonlinear/sensitive loads disturbs the quality of power supplies in distribution system. Dynamic voltage restorer (DVR) is a custom power device which helps to improve voltage quality in distribution system. In this paper three single phase H-Bridge PWM inverters are used for each phase so as to reduce the voltage rating of the series converters. Synchronous Reference Frame (SRF) theory along with In-phase compensation and Adaptive Fuzzy PI is used as control strategy for DVR. The poor performance by conventional PI controller with fixed gains when the system parameters and operating condition changes is improvised using Adaptive Fuzzy PI controller. The proposed DVR with control strategy is able to improve voltage quality by mitigating voltage sag, voltage swell, phase shift and harmonic problems.

Energy conservation has become a serious concern due to the fast depletion of crude oil and environmental hazards like global warming. This has resulted in the advancement of renewable energy technology worldwide. The aim of the work is to reduce the overall electrical energy price by optimally scheduling the load capacity in residential buildings so as to put to use the Renewable Energy Sources (RES) effectively and reduce the energy purchase from the grid. The modern building design incorporates the renewable energy resources to build smart buildings like the Zero Net Energy Building (ZNEB). ZNEBs are buildings where the annual energy consumption of the building is nearly equal to the net energy produced by the building via Renewable Energy Sources. Differential Evolution (DE) optimization method has been used to evaluate the optimum load scheduling which helps in minimizing the electrical energy cost. The appliances in the building are scheduled to operate during peak and off-peak hours, and a penalty has been imposed on consumer for violating the system constraints. The proposed work consists of hybrid system consisting of 1 kW Photovoltaic (PV) panel, Hybrid Energy Storage System (HESS) comprising of battery of 12 V, 7 Ah and six super capacitors connected in series of 3 V, 500 F each and ten household appliances integrated with the grid. The proposed system was simulated using MATLAB 2017a and obtained results are analyzed in the paper. When the DE optimization is employed the annual energy cost of Rs 7524 is obtained with constraints compared to Rs 10639 without constraints. There is a net annual energy saving of Rs 3115 proving an effective implementation of the proposed algorithm.

The long established battery chargers are having many drawbacks such as prominent ripple charging current, less efficiency and bulky in size. To overcome these drawbacks of conventional battery charger, several charging circuits have been proposed and inevitability force to design a high-performance battery charger with small in size and improved efficiency. In this paper solar photovoltaic system based half-bridge series–parallel resonant converter (HBSPRC) charger is proposed for battery interface. The converter is designed to abolish low and high-frequency ripple currents and thus take full advantage of the life of secondary battery circuit. This is achieved by designing converter switches turn on at zero current and zero voltage with switching frequency greater than that of resonance frequency which leads to freewheeling diodes need not have very fast reverse-recovery characteristics. The performance of the power converters depends upon the control method adopted; in this work fuzzy logic controller is used for controlling the output voltage of HBSPRC. The fuzzy control scheme for the HBSPR converter has been designed and validated in hardware implementation of HBSPRC switching technique. From the results, it is found that the proposed battery charging system which reduces the switching loss and voltage stress across the power switches which increases the efficiency of the converter.

The major power quality issue of voltage flicker has resulted as a serious concern for the customers and heavy power companies. Voltage flicker is an impression of unsteadiness of visual sensation induced by a light source whose luminance fluctuates with time. This phenomenon is experienced when an Electric Arc Furnace (EAF) as load is connected to the power system. Flexible AC transmission devices (FACTS) devices were gradually utilized for voltage flicker reduction. In this paper the FACTS device of Distribution Static Synchronous Compensator (D-STATCOM) is used to serve the purpose of mitigating voltage flickering caused by electric arc furnace load, which is efficiently controlled by Icosɸ control algorithm. The model of electric arc furnace is considered as a current source controlled by a non linear resistance, which had been simulated and performance was analyzed using MATLAB/SIMULINK Software.

The grid integrated renewable energy sources are becoming a common area of interest for power generation in the recent times. The design and development of efficient interfacing technologies to interconnect renewable energy sources with grid is catching a lot of attention among the researchers these days. The interfacing unit becomes crucial as renewable energy sources when directly connected to grid, can inject harmonic components that may deteriorate the quality of power. This paper proposes a mechanism to use shunt active filter as an interface between renewable energy sources and grid with a modified and efficient control scheme. The shunt active filter with this modified controller controls the real power supplied by the grid (source) in addition to its usual functions such as reactive power compensation, power factor correction and harmonic elimination. The non-linear load is diode bridge rectifier feeding resistive load and the unbalanced load also introduced to verify the controller performance. The simulation of the proposed system under both balanced and unbalanced load conditions have been done and the obtained results prove the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy system.

Algal Fuel Cells (AFC) are bioelectric devices that use photosynthetic organisms to turn light and biochemical energy into electrical energy. The potential of a fully biotic AFC still remains an unexplored area of research and hence it has led to rethink the prospective use of plant-based bioelectricity. AFC consists of an anode and a cathode connected by an external electric circuit and separated internally by a membrane/no membrane in which the growth of algae is assessed. The key parameters for evaluating the performance of AFC are electrodes, separators, oxygen supplement, nutrients and its configurations. By controlling these parameters, the electric power production can be optimized. This chapter discusses the recent trends examined by a number of researchers and are interpreted to gain a better understanding. It is stressed that a greater focus must be given for a complete comprehension of the algal processes required for the development of AFC applications. Thus, it can be concluded that a further development of AFC technology with reduced costs and improved performance is required for sustainable development.

As a major and most efficient equipment in electrical power system, power transformers requires more concentration on its fault monitoring and protection. The main cause of faults in power transformers are the stress due to both thermal and mechanical effects. The monitoring of the thermal stress/temperature of transformer oil and other parts can be used as a prime step to identify fault. Not only the temperature measurement, but identifying the measuring locations is also of greater importance. In this paper, a pre-fault detection system using optical fibre sensing technology has been proposed. Phosphorescence of the material has been used for the temperature sensing. Temperature of the selected hotspots of the transformers will be monitored continuously and fed back to the protection system including cooling systems. The protection equipments of the transformer can be activated well before the circuit breaker operates and the reliability of the system can be maintained. The proposed method of thermal stress monitoring and fault detection has been tested and validated on a 16 MVA transformer.

An innovative application of half-bridge series-parallel resonant converter (HBSPRC) for photovoltaic system and secondary battery interface is explained in this paper. This converter is designed for eliminating both low and high-frequency current ripples on the battery. This will helps to maximize battery life. The switching frequency greater than that of resonance frequency is preferred for operation, because the power switches turn on at zero current and zero voltage; thus, the freewheeling diodes need not have very fast reverse-recovery characteristics. Moreover the proposed battery charger circuit has a few components. To enhance the overall efficiency of the system energy conversion loss is to be minimized and the performance of the power converters depends upon the control method adopted. In this present work, Fuzzy logic based voltage controller and PI voltage controller have been designed, modeled and simulated in MATLAB/simulink platform and results are presented. © 2014 IEEE.
