Power Quality Improvement Using Unified Power Quality Conditioner with Distribution Generation

In recent scenario Distributed Static Compensator (DSTATCOM) resolves the current related power quality problems and Dynamic Voltage Restorer resolves the voltage related power quality problems. The Unified Power Quality Conditioner is the integration of DSTATCOM and DVR with common DC link. Due to the major advancements in Solar PV systems and its availability in reasonable cost at consumer end the world is moving ahead for Solar PV system for renewable energy generation. Generally, the electrical power to the DC link is supplied from source side. This paper presents the UPQC with Solar PV system. In proposed system the electrical power is supplied to DC link of UPQC using Solar PV system. The proposed system is designed and implementation in MATLAB simulink environment. The performance of the proposed system is analyzed under various conditions of source voltage variation, load unbalanced condition. After MATLAB simulation the proposed system is implemented in OP4510 Real Time Digital Simulator.
