Virtual synchronous machines with fast current loop
IFAC-PapersOnLine, 2020 Abstract Virtual synchronous machines (VSM) are inverters that behave towards the power grid like synchronous generators. One popular way to realize such inverters are synchronverters, whose control algorithm has evolved over time, but both theoretical analysis and practical observations show that the output currents of a synchronverter are very ...
