Distributed generation and renewable energy sources are hot research topics from past 10 years or so due to various reasons. The sudden load variation leads to change in voltage and frequency, and if nonlinearity presents, the T.H.D. variations will be more. Power quality controlled devices like DSTATCOM with battery energy storage system (B.E.S.S.) that controlled by pulse width modulation (P.W.M.) based voltage source converter (V.S.C.) in the distribution system would control the voltage, frequency and THD, indirectly power control. This paper presents an autonomous W.E.C.S. with zig-zag (Z2) transformer connected V.S.C. controlled DSTATCOM with BESS and its control scheme. It also shows the various MATLAB simulated results. It also contemplates the various performance parameters from previous methodology. It strategically concludes that the proposed system is effective in controlling voltage and frequency (V-f) and T.H.D. in voltage and current.
