Virtual Synchronous Machine Control of RES Plants in Isolated Power Systems

Because of the increase in renewable energy sources (RESs) share, new control strategies isolated power systems have been developed to improve frequency and voltage stability inverter-interfaced RESs. A source converter (VSC) with a virtual synchronous machine (VSM) is among most promising schemes. This paper demonstrates how VSM RES can be efficiently used dynamic small systems. In proposed analysis, RESs Mediterranean island are assumed interfaced grid by VSCs swing controller vector-current (VCC) two different options for reference current (RC) regulate at point common coupling (PCC) real output. The system modelled PSCAD environment, behavior tested case phase-to-phase fault. results simulations scenarios values parameters show effectiveness grids. Finally, level quality verified via harmonic analysis PCC voltage.
