One method is to equip energy storage system on the basis of traditional wind power generation system, and build a combined operation mode of wind storage.

    How does wind power affect heat storage system?

    According to the fluctuation of wind power, the operation of the heat storage system is adjusted. When the wind power fluctuates greatly, the CSP station can use its heat storage system to convert excess electric energy into heat energy for storage.

    Why do we need CSP power stations in wind power generation?

    The introduction of CSP power stations in wind power generation means to improve the absorption capacity of wind power generation by means of energy complementarity and balance the output fluctuations of the system.

    What is a battery energy storage system (BESS)?

    To overcome these challenges, battery energy storage systems (BESS) have become important means to complement wind and solar power generation and enhance the stability of the power system.

    Does multi-energy complementary system with solar thermal power station work?

    Most of the research on the multi-energy complementary system with solar thermal power station only stays on the configuration and optimization of energy storage capacity, but does not configure other power capacity according to the actual situation. In terms of model solving, many studies have adopted metaheuristics.
