The joint operation strategy of energy storage power station and photovoltaic power station based on typical output scenarios

摘要

With the continuous development of energy storage technology, how to improve the operation of energy storage power station and improve the joint operation of energy storage power station and new energy power station has become a current hot issue. In this paper, the joint operation strategy of energy storage plants and photovoltaic (PV) power plants is analyzed. Firstly, SOM clustering algorithm is used to classify the different output conditions of PV power plants in different seasons, and typical output scenarios are obtained. Then, the profit model of PV power plant and the model of energy storage station are established before and after their cooperation. Finally, an example is given to analyze the model, and the optimal strategy of associated the energy storage station and the PV power plant under different typical scenarios is obtained. It is proved that in the majority of typical scenarios, both of the energy storage station and the PV power plant can get more benefits.
