摘要： 本文提出了一种基于多代理系统（multi-agent system，MAS）的孤岛微电网（microgrid，MG）实时经济调度分布式优化策略，其中孤岛微电网由发电供应商、电力用户和储能运营商等多运营主体组成。该策略考虑了电力用户参与电价制定的权利，经过系统内部多运营主体共同议价决策出电能交易的出清电价和交易电能量，实现了微电网内供需功率平衡。为保护交易过程中各运营主体的内部隐私权，模型采用了异步交替方向乘子法对联盟效益最大化模型进行求解。仿真结果验证了该策略的有效性。

Abstract: This paper proposes a distributed optimization dispatch strategy for an isolated microgrid (MG) using a multi-a gent system (MAS). The isolated MG consists of suppliers, consumers and energy storage operators which are considered as agents. Based on the self-interest motivation market, a real-time price mechanism is proposed to optimize energy supply and demand, aiming to maximize the social welfare of each agent in the isolated MG. To achieve market equilibrium among all agents in the isolated MG, an asynchronous alternating direction method of multipliers (ADMM) algorithm is designed to provide market clearing price and solve power balance, where each agent only needs to exchange a small amount of information with its neighboring agents. Simulation results demonstrate the validity of the proposed strategy.

Key words: microgrid multi-agent system, real-time economic dispatch, distributed optimal, ADMM
