Abstract:
The incorporation of photovoltaic (PV) systems into power networks poses issues owing to the variability and intermittency of solar energy. This paper examines sophisticated control algorithms for photovoltaic inverters to promote grid stability, maximize energy conversion, improve power quality, and facilitate the smooth integration of dispersed renewable energy sources. This study conducts a thorough examination of current control methods and their shortcomings, identifying and assessing novel algorithms designed to address these issues. Significant contributions encompass the execution of Maximum Power Point Tracking (MPPT) techniques, voltage management at the Point of Common Coupling (PCC), synchronization methods for grid frequency and phase alignment, as well as measures for mitigating harmonic distortion and voltage fluctuations. Both simulation and experimental validations substantiate the efficacy of these control mechanisms across various climatic and grid conditions. The suggested solutions markedly improve photovoltaic system performance and reliability, promoting steady integration of dispersed generation and facilitating the advancement of sustainable power systems.
