M. Soman, P.V., M., and K. Ilango, “Design and control of a soft switching grid connecting inverter using PI controller”, in 2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016.[Abstract]


This paper describes control and design of a new single phase dc-ac converter with soft switching operation. This converter operates with soft switching under discontinuous mode of operation. A snubber capacitor is connected to the dc terminals of a full bridge converter configuration, because of this snubber capacitor an additional switch is required to disconnect it from the dc side. A new control approach is used for the implementation of the proposed grid connecting converter. The closed loop control is simulated using PSIM smart controller. Voltage signal which are control parameter responsible for real power exchange from the renewable energy source to grid are considered in the simulation. More »»

M. P.V. and Nair, M. G., “Performance analysis of different custom power devices in power park”, in 2016 - Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy, PESTSE 2016, 2016.[Abstract]


This paper discubes about the various custom power devices used in custom power park. The custom power plant ensures the delivery of high grade of power to customers. The performance of shunt active filter, DVR, SSTS, pabive filter and overall CPP controller are analyzed. Simulation is carried out using Matlab Simulink platform. The control algorithm used for shunt active filter and DVR are ICosO and IRPT respectively. A shunt pabive filter is designed to eliminate the lower order harmonics so that the rating of shunt active filter can be reduced considerably. The controller for SSTS is based on voltage detection scheme. The voltage of preferred and alternate feeders are sensed and given to the overall controller of custom power park.

This paper presents a control strategy for shunt active filter interface for distributed generation scheme without degrading the power quality in the grid. The control strategy used enhances the performance of shunt active filter by sharing active power being generated from distributed generation to grid as well as load in addition to regular functions such as current harmonic elimination, reactive power compensation, power factor correction. The modified control algorithm is designed and analyzed for non-linear load using MATLAB/Simulink. The simulation results shows good performance of controller for power quality improvement of distributed generation system interfaced through shunt active filter. © 2014 IEEE.

Developing efficient interfacing technologies to interconnect renewable energy sources with grid is a promising research area in renewable energy related applications. 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. Performance of the modified IcosΦ controller is compared with that of IRPT control algorithm. Two nonlinear loads are considered here namely AC voltage controller as soft starter for induction motor and a diode bridge rectifier feeding resistive load. Simulation of proposed system proves the effectiveness of using a shunt active filter as the interfacing unit for grid integrated renewable energy systems. ©2012 IEEE.

This paper presents an improved operation of the Custom power park with a newly proposed control algorithm for series active filter. Custom power devices operated for multiple customers in an industrial area form a common platform called custom power park (CPP). CPP delivers high quality high reliable supply than from the utility at different grades. The enhanced operation of CPP is proposed with GTO based static transfer switch, shunt and series active filters.The shunt active filter provides the harmonic and reactive power support for the park while voltage sag/swell and voltage harmonic mitigation is done by means of series active filter with a newly proposed control algorithm. The entire model of CPP is developed and operation is verified using MATLAB/ Simulink model. More »»

<p>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.</p>
