Primary frequency modulation capacity planning method considering shared energy storage joint participation of wind power cluster

Abstract

The invention relates to a planning model and a solving method for wind power cluster shared energy storage joint participation primary frequency modulation, in particular to a primary frequency modulation capacity planning method considering wind power cluster shared energy storage joint participation. A wind power output uncertainty model is established through probability distribution based on Weibull distribution, output characteristics of each wind turbine generator under a wind power cluster are comprehensively considered, shared energy storage is configured in a centralized manner to jointly undertake a primary frequency modulation task, and a relationship between reliability and economy is processed through chance constraint planning. And establishing a wind power cluster shared energy storage joint participation power grid primary frequency modulation capacity optimization model. And finally, the opportunity constraint is converted into a deterministic constraint solving method, so that the model solving efficiency is improved. According to the determined scheme, under the conditions that the number of wind turbine generators is increased and wind power cluster data is huge and complex, coordinated planning of economy and reliability of primary frequency modulation of the wind storage combined system is achieved, and the method has better solving efficiency and has application and popularization prospects.
