提出由上级电力市场Agent、微电网及发电公司Agent和元件级Agent组成多代理系统(multi-agent system，MAS)电力市场竞价体系。进而提出了基于这一体系的微电网利润最大化目标，针对此目标，分别提出微电网及发电公司Agent利润最大化竞价策略与微电网内部成本优化策略，并讨论了各Agent的具体功能。最后针对各个策略用算例验证了其有效性。

A bidding system for electricity market based on multi-agent system, which is composed of agents of higher level electricity market, agents of microgrid and generation companies and component-level agents, is proposed; then the profit-maximizing object of microgrids based on the proposed bidding system is given; and then the profit maximizing bidding strategy for microgrids and generation companies and internal cost optimizing strategy for microgrids are put forward respectively; moreover, the special functions of each sort of agent are explained. The effectiveness of the proposed bidding strategies is verified by calculation examples.
