    摘 要:随着微网技术的迅速发展,接入配电网的区域多微网系统已经越来越常见。提出了一种基于合作博弈策略的调度方法,建立针对多微网系统的合作联盟,先在子微网之间进行功率交换,而后子微网再与配电网进行功率交换,以提高多微网系统的经济性。介绍了多微网系统并对典型电源进行建模,引入合作博弈的基本概念,并建立起并网型多微网调度合作博弈模型,合作收益则使用 Shapley 值法进行分配。通过算例验证了该策略的有效性。

    Abstract: As the microgrid technology develops rapidly, regional multi-microgrid systems integrated into the distribution network have become more and more common.The paper proposes a scheduling method based on the cooperative game strategy. It first establishes a cooperative alliance for the multi-microgrid systems to make them exchange power. Then, sub-microgrids and distribution networks exchange power to improve the economy of multi-microgrid system. In the paper, the multi-microgrid system is introduced and the typical power source is modeled. Through introducing the basic concept of cooperative game theory, the grid-connection multi-microgrid scheduling model based on cooperative game theory is established, and the cooperative income is distributed by Shapley value method. The effectiveness of this strategy is verified by examples.
    Key words: multi-microgrid; scheduling; cooperative game; economic operation; Shapley value method
