The Distribution Network Coordinated Operation Considering Distributed Energy Storage System Integration

Distributed energy storage system (DESS) becomes more and more popular in the distribution network, especially in the era with largely increased the renewable energies. This paper proposed the day-ahead coordinated operation method of active distribution network considering distributed energy storage system integration and network reconfiguration. The objective is to minimize the energy loss of distribution network within one day. The DESS optimal operation model is proposed. The network reconfiguration considered in this paper is a multiple time segment reconfiguration. The purpose is to find a topology structure which can adapt to the load and DG variety within 24 hours. The proposed model and algorithm is verified with a TPC 84-bus system, the different switch operation times and different substation voltages are discussed. The results show the adaptability of the proposed methodology and the necessity to include the DESS and network reconfiguration in the coordinated operation.
