Research on Target Analysis and Optimization Strategy of Peak Cutting and Valley Filling based on Actual Engineering Requirements

The peak of power grid load curve gradually increases, resulting in a serious imbalance between supply and demand of the power system, and the proportion of new energy generation is also rising rapidly. If not handled properly, it will also cause serious wind and light abandonment. At present, the problems to be solved are as follows: in the aspect of behavioral purpose, based on the actual engineering needs, how to understand the target of peak cutting and valley filling more reasonably; In the aspect of problem solving strategy, how to use the complementary characteristics of resources to cut peaks and fill valleys better. Based on this, this paper studies peak cutting and valley filling, proposes new understanding and indicators, and puts forward optimization strategy of peak cutting and valley filling based on indicators combined with flexible resources such as energy storage and adjustable load. Finally, an example analysis shows that the proposed model can better solve the original serious problems, and by comparing the cost, it is concluded that the strategy of peak cutting and valley filling can achieve better peak cutting and valley filling effects.
