Virtual synchronous generators (VSGs) utilizing renewable energy sources (RESs) have been proven to be an appealing solution for overcoming the challenges of renewable energy sources (RESs) consumption in power systems. In order to address these issues, researches have been developed to improve the dynamic characteristics of VSG power systems. However, most of the studies at home and abroad focus on the negative impact of VSGs on the grid voltage, and few on the frequency, safety and efficiency of VSGs. The first part of this paper focuses on the VSG’s electromagnetic detail model with the ability to support the system voltage and frequency deviations, the second part discusses the mathematical investigation on its response as a VSG. Finally, according to the technical requirements of the power grid, mechanical and electromagnetic loads are simulated, the influence of service life is analyzed, and design suggestions are put forward.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
