The voltage violations can be mitigated by dispatching various var devices. As conventional regulation devices, such as on-load tap changer (OLTC) and switching of ca-pacitor banks (CBs), are limited by the slow response and discrete voltage regulation [7], it is difficult to provide ac-curate real-time voltage control for DGs. DG inverters generate nominal power during just a small fraction of the time, the remaining power capacity available in the inverters can be used for continuous voltage regulation.
