This paper analyzes the importance of grid-connected control of photovoltaic power generation system. The output power of photovoltaic power generation system has the characteristics of randomness, intermittency and fluctuation, which makes the grid-connected control of photovoltaic power generation system particularly complicated. The effective grid-connected control strategy can ensure that the photovoltaic power generation system can achieve stable and reliable grid-connected operation with the power grid under different working conditions, and improve the power generation efficiency and energy utilization rate of the photovoltaic power generation system. This paper introduces the main strategy of grid-connected control of photovoltaic power generation system in detail. These strategies include maximum power point tracking (MPPT) based control strategy, voltage and frequency based closed-loop control strategy, power prediction based optimization control strategy and so on. Each strategy has its own unique control principles and application scenarios, through the comprehensive use of these strategies, you can achieve the efficient and stable operation of photovoltaic power generation system. In the aspect of optimization, this paper discusses the optimization method of grid-connected control of photovoltaic power generation system. These methods include optimizing the operating temperature of photovoltaic cells, improving the conversion efficiency of photovoltaic cells, optimizing the control algorithm of inverters, and adopting advanced energy storage technology. By optimizing these key links, the grid-connected performance and economic benefits of photovoltaic power generation systems can be further improved. This paper summarizes the research results and future development trend of grid-connected control strategy and optimization of photovoltaic power generation system. With the continuous progress of technology and the expansion of application fields, the grid-connected control strategy and optimization of photovoltaic power generation systems will face more challenges and opportunities. Future research will pay more attention to improving the intelligent level of photovoltaic power generation systems, optimizing control algorithms, and improving the efficiency and economy of energy storage technology, so as to promote the wide application and sustainable development of photovoltaic power generation systems.
