... power electronic interface in control is accomplished using dq reference frame-based voltage WECS. The other benefits of MMC to be used in WECS are control scheme for voltage and frequency stabilization at the the modular submodule (SM) configuration in the power PCC by regulating the voltage at its reference value. Simulation studies show that all proposed ...
