Abstract:

At present, the share of new energy in the distribution network is increasing, and its inherent intermittency and volatility pose severe challenges to the management of the distribution network. To this end, a new energy distribution network coordinated optimization method based on reversible pumped hydro-storage (RPHS) is proposed, and an energy management system based on RPHS is constructed to minimize the levelized cost of energy (LCOE), and the coordinated optimization configuration of new energy is realized. The proposed method is verified through the design of simulation experiments. The results show that RPHS has achieved remarkable results in improving energy utilization efficiency, reducing operation costs, and system stability.

Key words: hybrid energy system, pumped hydro-storage, energy coordination optimization.
