Optimal configuration of energy storage for high penetration of flexible resource aggregation in new-type source-load distribution networks

Based on the characteristic of rich flexibility resources in high penetration new-type source-load distribution networks, and consider first aggregating the flexibility resources within the distribution network into virtual energy storage. Considering the capacity and output characteristics of virtual energy storage, the optimal model of energy storage capacity configuration is constructed with the optimal economy of the whole life cycle. A simulation model is built in CloudlEPS to solve the optimal capacity of energy storage. Compare it with the scenario that does not consider the aggregation of flexibility resources, and verify the advantages of this model in reducing initial investment in energy storage and improving the economic operation of the system.
