Abstract

The coordination operation between microgrids (MGs) and distribution network is an important problem when a large scale of distributed generations are connected to the grid. A multi-agent approach is considered as a preferred control scheme to promote bidirectional exchange of information between them. In view of the external characteristics of a MG as a power source or a load, an interactive economic scheduling model of distribution network with multi-microgrid is proposed based on multi-agent approach. Considering dynamic constraints, the distribution network confirms the output of every MG and generation company with the goal of operational cost minimization by decision making. Finally the genetic algorithm is used to solve a case of a distribution network with two MGs, and the result reveals the economic benefits of both distribution network and MGs.
多微电网配电网的经济调度
微电网与配电网的协调运行是大规模分布式发电并网时的一个重要问题。多智能体方法被认为是促进它们之间双向信息交换的首选控制方案。针对微电网作为电源或负荷的外部特性,提出了基于多智能体方法的多微电网配网交互经济调度模型。考虑动态约束,配电网以运行成本最小为目标,通过决策确定各电网和发电公司的出力。最后,利用遗传算法求解了一个配电网中有两个自动调速器的情况,结果表明了配电网和自动调速器的经济效益。
