摘要：

当前，新能源在配电网中占比持续攀升，其固有的间歇性与波动性给配电网管理带来严峻挑战。为此，提出一种基于可逆抽水储能（reversible pumped hydro-storage，RPHS）的新能源配电网协调优化方法，构建基于 RPHS 的能源管理系统，以最小化平准化能源成本（levelized cost of energy，LCOE）为目标，实现新能源的协调优化配置，并通过仿真实验验证所提方法。结果显示，RPHS在提高能源利用效率、降低运行成本、增强系统稳定性等方面成效显著。

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.
