Today’s modern world, all the frequently using electrical appliances ranging from consumer products to state of the art industrial products exhibits nonlinearity. Due to this the quality of the Grid becomes worse. It also pollutes, electrical point of view, the other healthy systems also. In this connection, various approaches have been put forth to minimize the harmonics in the supply which in turn improve the quality of the power Grid in terms of improving real, reactive power flow and power factor. This paper proposes the novel approach to enhance the power quality in the grid by using simple method to extract the harmonic current compared to time consuming d-q modelling approach. This novel control techniques exhibit excellent dynamic performance, easy to implement, high robustness and stability. The proposed control scheme is verified by comparing its performance with its counterparts. In this connection a testing scheme is developed and tested with the help of MATLAB/SIMULINK package and it agrees in line with our proposed scheme. |
