Analysis of AC / DC Hybrid Microgrid System Architecture and Typical Operation Conditions

With the high proportion of large-scale distributed wind and solar renewable energy penetration, China's energy supply structure and power grid architecture are undergoing profound changes. In order to deeply analyze and understand the operation characteristics of AC / DC hybrid microgrid system in the energy structure, this paper uses the literature method and case analysis method to discuss and analyze the system architecture design, operation control strategy and typical operation conditions of AC / DC hybrid microgrid, and obtains its basic operation rules, so as to lay the foundation for the accurate and rapid control of the following typical operation conditions. The research results of this paper can not only lay a theoretical and technical foundation for the in-depth discussion of AC / DC hybrid microgrid, but also provide useful reference for relevant workers and builders.
