With the progress of renewable energy technology, China's renewable energy shows a good prospect, but also faces some obvious constraints. The power system based on traditional energy can not fully meet the grid operation requirements of photovoltaic power generation and other volatile renewable energy, and there are still technical barriers for large-scale grid connection of renewable energy power generation. This paper mainly analyzes the existing problems and problems to be solved in the actual operation of photovoltaic grid connected system. The basic operation mechanism of photovoltaic grid connected system based on MMC technology is analyzed, and the mathematical model of MMC converter is established. ADRC control technology is used in current loop.
