Against the backdrop of global energy structure transformation, photovoltaic power plants, as an important component of clean energy, are constantly expanding in terms of construction and operation scale. However, the intermittency and instability of photovoltaic power generation limit its efficient utilization in the power grid. And the mismatch between the power generation curve and the electricity consumption curve leads to incomplete consumption of photovoltaic power, resulting in a certain degree of energy waste. 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.
