微电网环境下多约束复杂自主体网络建模与协调优化的研究

Microgrid is one of the most effective methods to utilize distributed renewable energy resources, and the power balance and economic dispatch are fundamental problems for the stable and economic operation of microgrids. In order to solve the power balance and economic dispatch problems in microgrids, the project intends to study the modeling and coordinated optimization for complex multi-agent networks with multi-constraints, based on the application requirements of microgrid and its features. According to the microgrid operation and control features, a number of typical multi-agent netowork models with those features will be established; The distributed control and optimization for the complex multi-agent networks will be studied to address the power balance and its optimization problems in microgrids and the relationship between the algorithm performance and communication topology will be qualitatively and quantitatively analyzed; the impact of various types of communication constraints on the algorithms will be considered, and the relationship between the algorithm performance and communication constraints will be analyzed in quality and quantity, and the coordination algorithms desgin under given communication constraints will be investigated. On one hand, these theoretical results will extend the research field of coordinated control and optimization for multi-agent networks; on the other hand, they will provide theoretical principles for analysis, design and construction of microgrids.
