构建弹性微电网是提高供电可靠性与安全性的重要途径，备受世界各国关注。然而，因微电网固有的多维多尺度时空特性、可变网络拓扑结构、复杂扰动演变机理等特征，使其恢复力的提升极具挑战性，所涉及的一系列关键理论和技术问题亟待解决。本项目拟首先揭示弹性微电网中关键概念的内涵，构建综合评价指标体系与基于信息熵的评估理论方法，为扰动抵御、适应、恢复等提供理论基础；然后深入分析各类扰动的时变特征及传播机理，建立扰动辨识数据库，提出基于扰动对弈防御理论的最优抵御策略；提出源-网-荷-储一体化的扰动分配与共同响应的新思路，设计基于虚拟同步电机集群的一体化扰动响应协调控制方法；研究基于多智能体的扰动恢复方法及“灰启动”策略；最后搭建仿真和实验平台验证新理论和新技术的有效性。本项目属电气工程、控制理论、计算机科学等多学科交叉前沿研究，对我国发展具有自主知识产权的弹性微电网并推动其应用具有重要的理论和现实意义。

Resilient microgrid construction is an important approach to improving the reliability and security of power supply system, and has achieved much concern around the world. However, due to the inherent multidimensional and multi-scale spatiotemporal characteristics, variable topologies and complex disturbance evolution mechanism, the resilience of resilient microgrid is difficult to be improved, thus a series of key theoretical and technical problems need to be solved urgently. Firstly, this project aims to reveal the key connotations and concepts of resilient microgrid, and construct the comprehensive evaluation indexes and theories based on information entropy to provide a theoretical basis for the disturbance resistance, adaptation and recovery. And then, the time-varying characteristics and propagation mechanism of all kinds of disturbance will be analyzed in depth, the identification database of disturbance will be established, and the optimal strategy based on the disturbance defense theory will be put forward. Afterwards, a novel approach to disturbance distribution and common response of source-grid-loads-storage integration will be proposed, and a disturbance response control strategy base on virtual synchronous machine cluster integration will be designed. In addition, the technologies of disturbance recovery and gray-start strategy based on Multi-Agent System will be studied. Finally, the simulation and experimental platforms will be developed to verify the effectiveness of the proposed theories and technologies. This proposal is the frontier research involved in multi-discipline of Electrical Engineering, Control Theory, and Computer Science and so on. The expected results of this project can not only provide important theories for resilient microgrid technique and develop the independent intellectual property rights, but also has important practical significance to promote the application of resilient microgrid.
