Abstract
In this proposed work, Synchronous Reference Frame (SRF) based control algorithm is used in Photovoltaic (PV) grid integration through Distribution Static Synchronous Compensator (DSTATCOM) with Battery Energy Storage (BES) system for simultaneous mitigation of power quality issues and for real power injection. In order to makeover the issues in the quality of power in the system by compensating neutral current, asymmetrical loads in the four wire three phase nonlinear and unbalanced load distribution system. The highest power of PV is tracked using Incremental Conductance (Inc) method and the voltage of DC bus is preserved by Bidirectional DC-DC Converter (BDDC). The proposed system works as PV-DSTATCOM mode which performs DSTATCOM operation by improving power quality with the capability of transferring the generated PV power to the consumers and Grid, and in BES-DSTATCOM mode it supplies power to the utility load. The proposed system is implemented and modeled for 11kV/440V utility system. The results have been obtained using sim power system tools in MATLAB/SIMULINK environment.
