摘要：

孤岛微网的经济运行越来越受到关注,针对目前孤岛微网集中式控制中存在的通信量大、通信成本高、控制器易受攻击和拓展性差等问题,本文提出了一种基于分布式控制算法的孤岛微网经济优化运行方法。该方法不需要中央控制器,仅需通过相邻微源之间交换各自的微增率,就能实现微网运行在经济最优状态,同时提高了系统的控制性能。最后本文通过Matlab仿真算例验证了算法在孤岛微网经济运行方面的鲁棒性,有效地解决了集中式控制中存在的通信信息量大、通信成本高等问题。

Abstract:

The economic dispatch of islanding microgrids is gaining more and more attention. In view of the problems such as large amount of communication information, high communication cost, weak attackability and expansion in the centralized control of isolated islanding microgrids, a fully distributed microgrids economic dispatch method is proposed, which is based on the distributed algorithm only through the information exchange of the neighboring nodes about the respective micro incremental rates, and can achieve the optimal economic operation of microgrids, and improves the system control performance. The proposed method is verified through simulation by MATLAB for the economic dispatch of the islanding microgrids. The simulation results show that the proposed method can effectively solve the problem of large amount of communication information and high communication cost in centralized control method for the economic dispatch of microgrids.

Key words: Islanding microgrids, distributed control, centralized control, economic dispatch
