The traditional distributed user-side distributed energy storage control can only provide energy storage and supplement the local distributed power supply. It is unable to interact with distributed power supply, DC low-voltage distribution systems, and different types of low-voltage DC loads.
As a supplement to large power grids, DC microgrids with new energy access are increasingly widely used. However, with the increasing proportion of new energy in DC microgrids, its output fluctuations directly affect the overall stability of the microgrids. Distributed energy storage can smooth the output fluctuation of distributed new energy.
Distributed energy storage can greatly improve the power quality and reliability of distributed power supply 9, 10. On the other hand, there is a certain contradiction between distributed power generation and user power consumption in the time dimension.
Considering that the arrangement of storage significantly influences the performance of distribution networks, there is an imperative need for research into the optimal configuration of DG and Energy Storage Systems (ESS) within direct current power delivery networks.
In this paper, an AC-DC hybrid micro-grid operation topology with distributed new energy and distributed energy storage system access is designed, and on this basis, a coordinated control strategy of a micro-grid system based on distributed energy storage is proposed.
