Using demand response (DR) and improving the distributed energy resource (DER) are efficient ways to fulfill the requirement of the power generation and transmission construction.It is difficult for traditional distribution network to completely satisfy the DER access with high permeability.Meanwhile,the DR based on the price and incentive mechanism is lack of driving force under current policy and market environment.To solve the above problems,this paper takes the energy storage system of distribution network hierarchically,exerts the initiative of energy storage system through hierarchical decentralization and responsibility authorization,and energy storage with different hierarchies carries out demand response via autonomous coordinate control.The strategy can improve distributed generation permeability,delay the upgrading and rebuilding of the distribution network,increase the asset utilization,meet the requirement of the regional distribution network reliable operation,power quality,and power supply reliability,etc.,and achieve the application of energy conservation in power system.The active power demand management system based on this research result has been applied in the national energy application technology study and engineering demonstration project,which proves the practicality and efficiency of the strategy.%开展需求响应(Demand Response,DR)和提高分布式发电(Distributed Generation,DG)渗透率可以有效地缓解输电和发电建设要求.传统配电网的无法适应DER高渗透率接入,基于价格和激励的需求响应在现有的政策和市场环境下推广应用驱动力不够.为了解决上述问题,将配电网储能系统进行分层分级,通过层级分权和责任授权发挥储能系统的主动性,不同层级的储能通过自主协调进行需求响应.该方法可提高分布式电源的渗透率,延缓配电网升级改造提升资产利用率,满足区域配电网稳定运行、电能质量、供电可靠性等,促进储能在电力系统中的应用.基于该研究成果研制的主动配电网需求侧管理系统已应用于国家能源应用技术研究及工程示范项目,实践验证了策略的有效性和实用性.
