Application of multi-agent system in microgrid

分布式电源的复杂和多样性增加了微电网能量管理和控制的难度,因此基于多智能体系统(Multi-agent system,MAS)的分布式分层协同控制策略被提出,其具有平衡功率和能量、稳定电压和频率、实现资源优化管理和经济协调运行的优点。该文主要对MAS在微电网中的应用情况进行全面系统的分析、对比、归纳总结。对比分析了微电网分层控制策略,研究表明基于MAS的分布式分层控制可以提高系统灵活性、可靠性。研究了不同的MAS建模方法的优缺点,为优化控制策略的选择提供依据。对通信时延、一致性协议、即插即用拓扑等方面进行阐述,综合分析了不同通信补偿方法。归纳出下一步基于MAS的分布式分层协同控制与优化的研究方向。

The complexity and variety of distributed generation increase the difficulty of energy management and control of microgrid,and distributed hierarchical coordinated control strategies are proposed based on the multi-agent system(MAS),which shows the advantages of balancing the power and energy,stabilizing voltage and frequency,and achieving economic and coordinated operation in microgrid.This paper makes a comprehensive and systematic analysis,comparison and summary of the application of the MAS in microgrid.Firstly,the hierarchical control strategies of microgrid are compared and analyzed.The research shows that distributed hierarchical control based on MAS can improve the flexibility and reliability of the system.Secondly,the merits and drawbacks of different MAS modeling methods are studied to provide a basis for the selection of optimal control strategy.With respect to the communication delay,consensus protocol,plug and play topologies are elaborated,and the different communication delay compensations strategies methods are comprehensively analyzed.Finally,the future trends in terms of distributed hierarchical coordination control strategies and optimization schemes based on the MAS are summarized and proposed.
