Description

technical field [0001] The invention relates to wind power generation, in particular to a control system for wind power energy storage frequency modulation and peak regulation. Background technique [0002] How to solve the energy crisis and the resulting environmental crisis has become a major research topic that is facing the sustainable development of the global economy and needs to be solved urgently. As a green energy source, wind power is one of the lowest-cost greenhouse gas emission reduction technologies. Therefore, it is favored by governments of various countries and develops rapidly. However, due to the randomness, intermittentness and uncontrollability of wind, wind turbines have many adverse effects when they are running off-grid or grid-connected. Specifically, due to the variability of the wind, the wind turbines generate fluctuations, random changes or zero output of electric energy, and these fluctuations, random changes and zero output further have a neg...
