Abstract

With the increase of the installed capacity of electrochemical batteries, how to maximize the benefit of large-scale energy storage system(ESS) has become an urgent problem. Therefore, this paper intends to establish an optimization model of aggregator based on users’ participation evaluation. Firstly, the idea of hierarchical capacity optimization for ESS is introduced, and the charging and discharging power distribution of distributed energy storage system(DESS) is evaluated. Then, based on the price-based demand response model, a DESS aggregation model based on herd psychology is established to evaluate the functional relationship between subsidy and participation. Finally, the capacity optimization model of aggregator participating in peak load regulation based on users’ participation evaluation is established. An example is given to verify the effectiveness of the proposed model.
