Abstract: With the continuous promotion of energy supply side structural reform, China’s energy consumption and supply, energy structure transformation and energy system show a new trend, and distributed energy is developing rapidly. Energy storage has the advantages of making up for intermittent new energy and good frequency modulation performance. Its participation in the power market and auxiliary service market is the current development trend. The application of energy storage participating in auxiliary services and the algorithm of various evaluation rules of grid connected operation of energy storage power station and auxiliary service management technology support system are studied, and the calculation is illustrated by an example.
Keywords: energy storage; ancillary service; power market

储能系统作为智能电网、可再生能源高占比能源系统、“互联网+”智慧能源的关键支撑,储能的充放电不受天气影响,可与风电、光伏等间歇式形成互补,助力电网安全稳定运行。随着我国持续推进能源供给侧结构性改革,推动能源发展方式由粗放式向提质增效转变,我国能源消费供给、能源结构转型、能源系统形态呈现新的发展趋势,在碳达峰、碳中和国家战略目标驱动下,储能作为支撑新型电力系统的重要技术和基础装备,其规模化发展已成为必然趋势[1]。2020年国内电化学储能新增装机规模逆势而涨,达到1.56 GW,同比增长145%,截至2020年底,国内电化学储能的累计装机规模为3.27 GW,十四五期间,随着储能商业模式逐步清晰,电化学储能装机量将呈现高速增长态势。
在国外,储能已经是调频辅助服务市场的重要参与者。我国在储能参与辅助服务的市场应用场景、商业模式、效益评估方面已有深入研究。……
