Sažetak
The escalating global demand for distributed generation systems has driven the widespread integration of Solar Photovoltaic (PV) system into the distribution grid. This paradigm shift, while promising in meeting energy demands, introduces intricate power quality challenges within distribution systems. This research deals with the comprehensive analysis and strategic mitigation of PQ issues of 0.3MW solar PV system, featuring advanced components like an MPPT tracker and a controlled load. Utilizing PSCAD software for simulation, the study incorporates vital input parameters like irradiance and temperature to generate 0.3MW power. The generated power undergoes a meticulous transformation process through boost converter, ensuring both voltage regulation and Power Point Tracking. The regulated DC power is then seamlessly supplied to the voltage source inverter, facilitating its supply to the Point of Common Contact (PCC), where both the conventional grid and the controlled load are intricately connected. The study employs advanced techniques, including FFT analysis to measure THD at the inverter output. Additionally, an in-depth examination of voltage imbalances adds further granularity to the power quality assessment. The THD values for inverter current and voltage are systematically evaluated through FFT analysis, offering insights into the harmonic characteristics of the system. As a strategic measure to mitigate THD and enhance overall power quality, a Static Var compensator is introduced at the inverter output. This intervention proves effective, showcasing a substantial reduction in THD levels. The research contributes significantly to the understanding and management of PQ challenges associated with the integration of solar PV systems in distributed generation scenarios. Through its comprehensive analysis and targeted mitigation strategies, the study provides valuable guidance for ensuring integration of renewable energy sources into the evolving landscape of modern power systems.
