When the load is low, the output of RE may be in the peak period, and ESS can store the remaining electric energy, improve the utilization capacity of RE and avoid the curtailment of RE. During the peak period, ESS discharge plays a supporting role to avoid the shortage of electricity to a certain extent.
In this paper, a comprehensive configuration strategy is proposed to reduce the peak load and peak-valley difference in distribution networks. The strategy includes the allocation of centralised energy storage in transformer stations, the allocation of decentralised energy storage on lines and the upgrading of distribution lines.
In the scenario of high penetration level of renewable energy in the distributed generation, BESS plays a key role in the effort to combine a sustainable power supply with a reliable dispatched load. Several power converter topologies can be employed to connect BESS to the grid.
