With the transformation of the global energy structure and the rapid development of renewable energy, photovoltaic power plants, as an important component of clean energy, have continuously expanded their construction and operation scale. However, photovoltaic power generation has the characteristics of intermittency and instability, which limits its efficient utilization in the power grid. Energy storage technology, as a key means to solve this problem, is of great significance for the stable operation and energy management of photovoltaic power plants.
