Advanced distribution automation system for control of PV inverters to enhance PV penetration

The PV penetration level of a distribution system is often limited by the violation of voltage variation introduced by large intermittent power generation. This study investigates the control of PV inverters. To achieve better control of PV inverters, the Advanced Distribution Automation System is proposed in this paper to monitor the system voltage variation due to large ramping rate of real power injection by PV systems. The ADAS system is also considered to support the fault detection, isolation and service restoration (FDIR) for enhancement of system reliability. In reactive power compensation for system voltage control during peak solar irradiation in order to increase the PV installation capacity of a distribution feeder without causing voltage violation problem.
