基于MAS的微电网即插即用理论研究

Study on the Plug and Play Theory in Micro-grid Based on MAS

即插即用理论是微电网研究的热点,目前国内外对即插即用理论的研究多侧重于设计单个微源并网的电力电子控制系统,而很少研究多个微网元件之间的协调控制策略。首先介绍了微电网的优缺点以及即插即用在微网中运用的理论基础,构建并阐述了以电网Agent、微电网Agent和元件Agent组成的微电网3层控制体系,设计了基于MAS系统和电力电子控制技术的即插即用模型,并详细分析了微电网元件协调控制策略。

The Plug and Play theory becomes a focus in the micro-grid research. However, the research ongoing both at home and abroad concentrates mainly on designing the electronic power control systems fora single micro-source with little attention paid to the coordinated control strategies of multi micro-grid elements. This paper first introduces the advantages and disadvantages of the micro-grid, as well as the theoretic application foundation of the ＇Plug and Play＇ in the micro-grid. A 3-tier control system is established which contains the power grid Agent, the micro-Grid Agent and component Agent, and elaborates the control system. A ＇ Plug and Play＇ modelis also set up which is based on combination of the power electronic technology and Multi-Agent system （ MAS ） and finally the coordinated control strategy of the model is closely examined and studied.
