Power Quality Improvement in Renewable Energy Sources Based Power System Using DSTATCOM Supported by Battery Energy Storage System

A technique for improving quality of power in a renewable energy (RE) sources based power system is introduced in this manuscript. Proposed technique is focussed on the use of distribution static compensator (DSTATCOM) incorporated with a battery energy storage system (BESS) and placed in parallel with dc link capacitor. Control of DSTATCOM is achieved with the help of synchronous reference frame theory (SRF). Hybrid power system is simulated by modifying IEEE-13 nodes test network by integrating wind generator, solar photovoltaic (PV) system and DSTATCOM. Improvement of power quality (PQ) events associated with operational events such as synchronization and outage of wind generator and solar PV system is achieved. Simulation results establishes that technique proposed in this manuscript is found to be effective for PQ improvement in hybrid power system during operational events of outage and synchronization of renewable energy (RE) generator.
