The energy storage system effectively smooths the fluctuations of wind power and photovoltaic power through charging and discharging regulation, making the total output of the system closer to the load demand curve. Figure 7. Annual power generation output and load curve.
Overall Structural Framework of the Model The wind–solar–hydro–storage multi-energy complementary system is an intelligent coordinated energy supply system that integrates multiple energy forms such as wind energy, solar energy (hydropower, photovoltaic), hydropower, and electrochemical energy storage.
The benefits of wind power and photovoltaic power are relatively high, while the benefits of energy storage are relatively low. However, the energy storage system plays an irreplaceable role in regulating the balance of power supply and demand and helps to improve the stability and reliability of the entire system.
