中文摘要： 随着能源革新和电网智能化战略的快速推进，以独立或脱网自治运行为特征的电力系统将在未来的发-输-配-用电环节中发挥重要作用。自治电力系统是一个具有高随机性、低抗干扰性、拓扑结构多变、运行工况复杂等特征的非线性动力系统，基于源荷储分散式协同的紧急控制是维持自治电力系统稳定运行的有效方法。本项目引入多智能体分散式协同理论，从协同控制框架、信息交互方法、协同紧急控制策略、仿真及实验验证四个方面展开深入研究，提出适用于不同规模（自治微电网/区域自治电力系统）、不同控制模式（主从/对等模式）的分散式信息交互方法（单层/双层/牵制一致性），设计基于不同信息获取和分享方法的分散式协同紧急控制策略，解决主agent依赖、信息时延、一致性收敛、拓扑结构多变和过控过切等一系列难题，为建立自治电力系统分散式紧急控制体系提供重要的理论支撑和技术支持。

英文摘要： With the rapid propulsion of energy innovation and power grid intelligent strategy, a kind of power systems characterized by autonomous running in islanded operation mode or islanding from main grid will play an important role on electrical generation - transmission - distribution and utilization in the future. An autonomous power system is a high randomness and low anti-jamming nonlinear dynamic system with changing topological structures and complex operation conditions. The cooperative emergency control based on the distributed cooperation of energy sources, loads and energy storages is an effective method to maintain the stability of the autonomous power system. In this project, a multi-agent system based decentralized cooperative theory is introduced and studied from four aspects: a) the framework of cooperative control, b) the information exchanging method, c) the cooperative emergency control strategy, d) simulation and experimental validation. The decentralized information exchanging methods (single-layer / two-layer / pining consensus) are put forward to adapt for different scaled (autonomous microgrids /regional autonomous power systems) autonomous power systems under different control modes (master-slave / peer to peer). Accordingly the decentralized cooperative emergency control strategies are proposed based on the different information exchanging methods to solve a series of problems including the dependence of master agent, information time delays, convergence of consensus algorithm, topologies changes, over control and over shed. Research achievements of this project can lay a theoretical foundation and technical guidance for the decentralized emergency control of autonomous power systems.
