APPARATUS AND METHOD FOR CONTROLLING CVCF ESS CAPACITY OF STAND-ALONE MICRO GRID

摘要

The present invention relates to a CVCF ESS capacity control device and a method of the stand-alone microgrid, the CVCF ESS capacity control device of the stand-alone microgrid according to an embodiment of the present invention, when the ESS is operated in the CVCF control mode, An indirect voltage regulation (IVR) for providing a compensation parameter for generating a compensation phase angle for arbitrarily varying a system frequency generated according to a system load variation with respect to a predetermined constant frequency; And a DQ / ABC converter configured to perform coordinate transformation of the D / Q voltage into a three-phase AC voltage for controlling the converter of the ESS using the generated compensation phase angle.
