电力现货市场下山东电化学储能电站净收益分析

Analysis on the Net Revenue of Electrochemical Energy Storage Power Station in Shandong Province Based on Electricity Spot Market

总结山东电力现货市场下电化学储能电站的相关政策。通过分析储能电站的各项收益、费用,得出电化学储能电站净收益的计算公式。通过分析电站净收益与上网电量、度电价差、综合效率、采用“两充两放”运行策略的关系,研究典型工况下临界点度电价差。通过山东某在运100 MW/200 MW·h电化学储能电站案例分析验证了净收益计算公式的有效性。研究结果可以为优化电站运行策略、提高电站收益水平提供参考。

The relevant policies in Shandong province under the background of electricity spot market were summarized.The calculation formula of the net revenue of the electrochemical energy storage power station was obtained by analyzing the income and expenditure of the power station.The critical point electricity price difference under typical working conditions was studied by analyzing the relationship between the net revenue of power station and on-grid electricity,electricity price difference,comprehensive efficiency,and the application of"charging twice and discharging twice"strategy.The effectiveness of the formula was verified by case analysis of an operational 100 MW/200 MW·h electrochemical energy storage power station in Shandong province.The research results can provide a reference for optimizing the operation strategy of power stations and improving the income of power stations.
