摘　　要：针对大规模风能以及太阳能等不可控新能源并网引起电力系统功率波动、峰谷落差大等问题,提出电-甲醇混合储能系统,通过电化学储能与电解CO_(2)制甲醇的甲醇储能相结合,在提高电力系统运行稳定性的同时,电解CO_(2)制甲醇,降低温室气体含量。同时针对电力系统电压波动导致电解CO_(2)制甲醇效率低的问题,提出一种新型基于甲醇电解槽的轮值控制策略,通过优化电-甲醇混合储能系统的容量配置,使电站功率波动满足国家规定。To address the issues of power fluctuations and significant peak-to-valley differences caused by the integration of large-scale uncontrollable renewable energy sources such as wind and solar power into the grid,a hybrid energy storage system based on electric-methanol is proposed.This system combines electrochemical energy storage with methanol production via CO_(2)electrolysis,thereby enhancing the operational stability of the power system while simultaneously reducing greenhouse gas emissions through methanol production.Furthermore,in response to the low efficiency of CO_(2)electrolysis for methanol production caused by voltage fluctuations in the power system,a novel duty-cycling control strategy based on a methanol electrolyzer is introduced.This strategy optimizes the capacity configuration of the electric-methanol hybrid energy storage system to ensure that the power fluctuations of the power station can meet national regulations.
