Abstract

Renewable energy generation systems are promising energy sources, however, they have a problem that they do not have, in general, inertia and synchronous power. A system with low inertial and synchronization forces has low stabilizing capability, and such systems are vulnerable to network fault and can cause large frequency fluctuations. This paper focuses on a large storage battery and a permanent magnet synchronous generator (PMSG) based variable-speed wind power generator, and a new cooperative virtual inertia and reactive power control system between them which is based on Fuzzy Logic controller and asymmetric hysteresis deadband is proposed and designed. Its effectiveness on the system stability enhancement during a grid fault is confirmed by simulation analyses on PSCAD/EMTDC.
