Power Quality Analysis with Power Management of Wind Penetrated Utility Grid Parameter by Battery-Supported Bi-Directional Converter Device

The article offers an optimistic approach to using battery energy storage devices (BESD) to reduce the effects of grid disturbances caused by switching events and the penetration of variable wind power. A bidirectional converter distribution static compensator (BDC DSTATCOM) is used to accomplish this. When the test system needs energy. In order to take control of the BDC DSTATCOM and store it in the BESD based on generation through power flow between the load bus and the BESD, synchronous reference frame theory (SRFT) based techniques are used. A test system comprising five buses was used for this investigation. Of the five buses, Bus1 provides a platform for sharing power between the electric grid (G) and the testing system; Bus2 integrates BESD with a 4 MW load (L1) capacity, which is connected by circuit breakers CB2 and CB3, respectively, to switch events ON and OFF and measure the effectiveness of BESD in mitigating grid disturbances in terms of transients during load switching; Bus3 and Bus4 are interfaced through trans-mission lines TL1 and TL2, providing power to local network loads. The Bus5, a 1.5 MW wind power plant (WPP) with transmission line TL3, integrates RE sources. In terms of power contribution to the load, voltage profile enhancement during switching events, grid parameters like voltage and current through evaluation of total harmonic distortions (THDs) is and analysis by the software MATLAB tool, its goals are to ascertain the effectiveness of the proposed method by power flow between BESD and the utility grid.
