摘要(Abstract):
构建新型电力系统是实现“碳达峰、碳中和”的重要途径之一,未来新型电力系统面临新能源出力间歇性、系统转动惯量持续下降、电网稳定水平降低、发用电平衡困难等挑战。电网调节能力相对不足,亟待引入更多灵活资源参与系统调节。对此,设计了包含调频、调峰、备用等品种在内的第三方独立主体辅助服务市场机制,建立市场准入、交易组织、调用执行、费用结算等组织流程,吸引源网荷储各侧并网主体资源,共同承担电网所需的各类辅助服务,有效提升了电网调节能力和系统运行效率。最后针对备用市场试点实践中发现的问题提出了相关建议。
It is one of the key avenues to achieve emission peak and carbon neutrality by building new power system.In the future,the new power system will face challenges such as intermittent new energy output,continuous decline of system moment of inertia,reduction of power grid stability level and difficulties in balancing power generation and consumption. Since the regulation capacity of power grid is relatively insufficient,it is urgent to introduce more flexible resources to participate in system regulation. Therefore the paper has designed a third-party independent entity auxiliary service market mechanism including frequency modulation,peak shaving,spinning reserve,etc.,and established organizational processes such as market access,transaction organization,allocation execution and expense settlement,which can attract grid-connected main resources including source,network,load,and storage to jointly undertake the auxiliary services required by the power grid to improve the power grid regulation capacity and system operation efficiency. Finally,relevant suggestions are put forward according to the problems found in the pilot practice of spinning reserve market.
