PERFORMANCE EVALUATION AND POWER QUALITY ANALYSIS OF SOLAR PV-UPQC CONNECTED WITH MICRO GRID
AbstractNon-renewable technologies have traditionally been used to satisfy the world's electricity need, however that contributes to increased prices, environmental degradation and global climate change. The power industries now focus and use sustainable forms of electricity, including wind, hydro, tidal and solar and help them to solve the boundaries of conventional energy sources. Solar Photovoltaic (SPV) is apparently increasingly important among renewable energy sources due to its features such as static, noise-free, non-fuel requirements, easy to maintain and ecologically friendly functionalities. The power-conditioning circuitry connects the SPV system to the utility grid. This power-conditioning circuitry has an integrated filtering and grid interconnection functionality. In existing distribution systems, reactive loads like motor drives, fans, pumps and electronic power converter have produced a significant volume of energy usage. Usually such loads drain the lagging power factor sources and thus increase reactive power burden in an electric power distribution network. Static Synchronous Compensator (STATCOM), Dynamic Voltage Restorer (DVR) and Unified Power Quality Conditioner (UPQC) are in the Custom Power Devices (CPD) family and are used to mitigate for current and/or voltage waveform power quality issues. The UPQC consists of Active Power Filters (APFs) both in shunt and series. Shunt and series connected APFs are among the best design control devices, which counteract the impact of current and voltage disturbance. The conventional UPQC is not supported by the Distributed Generation (DG). The DC- link of the UPQC is therefore supported by a storage capacitor. The UPQC with a DC-link storage condenser cannot provide long-term compensatory steps against current and voltage-based fluctuations and reactive strain as its storage capacity are insufficient. In this work we are about to eliminate the PQ issues generated due to non-linear loading and grid connected PV-system with a versatile UPQC controller, Which is preferred in the distribution system. Photo Voltaic (PV) tied Unified Power Quality Conditioner (UPQC) are connected back to back through dc-link capacitor and have been reported for simultaneous mitigation of both current and voltage related PQ issues. The UPQC has its own supply system which is energized through PV system.
