The large-scale energy storage power generation system is composed of photovoltaic modules, energy storage battery systems, bidirectional converters, grid-connected inverters, box-type substations and other equipment. After the renewable energy is connected, the DC power is converted into AC power through the grid-connected inverter, and the voltage is boosted and then connected to the grid. Aiming at the irregular and intermittent output characteristics of photovoltaic power generation or wind power generation, compared with other energy storage systems, lithium battery energy storage systems have faster response speed, smaller volume, longer life, and better performance, and the function of smoothing electric energy output and energy consumption.
