According to an optimizing collocation result solved by an energy storage system optimizing collocation model, the energy storage system of each collocation can be in an optimal scheduling state during operation and work.

Description

technical field [0001] The present application relates to the field of electric power, and in particular to an energy storage system configuration method and system. Background technique [0002] With the development of technology, people have higher and higher requirements for energy storage system configuration. [0003] The existing large-scale photovoltaic energy storage system configuration method obtains the charging and discharging control strategy of the energy storage system by using the first-order low-pass filter algorithm to process the photovoltaic output power, and takes the annual average minimum cost as the objective function to establish the energy storage system The (ESS) optimal configuration model is relatively simple, and it does not fully reflect the role of the energy storage system. The optimal configuration results obtained cannot guarantee that each configuration of the energy storage system is in the optimal scheduling state during operation. [0...
