METHOD FOR RESTRICTING OUTPUT POWER OF DISTRIBUTED POWER AND VOLTAGE STABILIZATION SYSTEM USING SAME

摘要

The present invention relates to a method for restricting output power of distributed power and a voltage stabilization system using the same. According to an embodiment of the present invention, provided is a method for restricting output power of distributed power, which includes the steps of: determining whether to perform a charging procedure or a discharging procedure through comparison of a distributed power supply output voltage and a discharge starting voltage for restricting a system overvoltage through an energy storage system (ESS); comparing the distributed power supply output voltage with a restriction voltage, which is a reference voltage for performing the charging procedure according to the determination resu determining the magnitude of the charge power using the charge/discharge control unit power according to the comparison result to perform the charging procedure for the energy storage system; and adjusting the charge power according to a result of the comparison of the distributed power output voltage with each of the restriction voltage and the discharge starting voltage.;COPYRIGHT KIPO 2019
