With increasing penetration of renewable energy sources, virtual synchronous generator (VSG) control is playing an increasingly vital role in islanded microgrids’ frequency stabilization. However, frequency stability becomes a critical challenge when multiple VSGs operate in parallel within an islanded microgrid. This paper …

With the development of Chinese space technology, spacecrafts combination system is constantly established. Solar panels of some spacecraft are blocked due to orbital attitude and space position, which leads to insufficient power generation capacity and difficulty in meeting load requirements. Therefore, the …
