Optimization and Security Control of Microgrids Based on Cyber Physics System

In order to study the optimization and security control of the microgrids based on cyber physical system, this paper starts from the research of the classical system architecture. We firstly model the microgrids based on the cyber physical system, and describes the basic ways of cyber attacks. This paper introduces the classic three-level control architecture and control strategy of microgrids system, and the network attack defense model and security control model. At last, it discusses the optimization possibility of the microgrids control, operation and maintenance mode, and the optimization approach of improving its defense capability against network attacks.
