客座编辑社论：基于构网型变换器的可再生能源主导电力系统动态性能与灵活性提升专题

INVERTER-BASED distributed generation(DG)and re-newable energy sources(RESs)are recognized as key ele-ments to address the challenge of economically harvesting energy while,at the same time,achieving net-zero targets.However,inverter-based generation decreases the physical in-ertia available in the system and increases uncertainty.More-over,recent studies have highlighted that relatively high inte-gration of DGs/RESs can negatively impact on power grid dynamics,power quality,frequency control,voltage regula-tion,as well as other control and operational issues.All these issues significantly limit the penetration of DG and RESs.
