摘　　要：在双碳目标激励下,分布式电源将迎来快速增长阶段。微电网作为相对独立的系统,能够通过源网荷储智能互动平抑分布式电源出力波动,有利于分布式电源的友好接入和就地消纳,具有广阔的前景。为实现多微电网对分布式电源的有效管理,更好地发挥微电网对分布式电源的支撑作用,提出了一种分布式能量管理策略。通过配置微电网能量管理系统(microgrid energy management system,MGEMS)的方式进行电力信息交换和运营,并采用交替方向乘子法(alternating direction method of multipliers,ADMM)对成本问题进行迭代求解;通过算例分析,验证所提方案的有效性、优越性与可拓展性。To peak carbon dioxide emission and achieve carbon neutrality,distributed power generation is in a stage of rapid growth.As a relatively independent system,microgrid can smoothen the output fluctuation of distributed power through intelligent interaction between source network and load storage,which is conducive to the friendly access and local consumption of distributed power,therefor it has broad prospects.In order to realize the effective management of distributed power by multiple micro-grids and better play the supporting role of micro-grid on distributed power,this paper proposes a distributed energy management strategy.Power information exchange and operation are carried out by configuring Microgrid Energy Management System(MGEMS),and the Alternating Direction Method of Multipliers(ADMM)algorithm is used to iteratively solve the cost problem.Finally,a case study is used to verify the effectiveness,superiority and scalability of the proposed scheme.
