Testing System for PV Grid-Connected Power Condition Systems with Support for Ancillary Services

Due to the high spread of photovoltaic (PV) systems in low voltage distribution grids there is a substantial number requirements for connection these systems. Therefore, several tests should be performed before integration PV into grid. Moreover, new have been established that are most likely implemented near future. To provide and verify if accordance with recommendations, testing setup was developed. This system consists controllable power source prepared receive energy inject it In fact, imposes voltage, amplitude frequency, simulate perturbations Since under test must standards’ specifications, then emulates grid energy. also able ancillary services, including ones support imbalanced networks. A fast robust control will used this source. Several experimental from developed prototype presented.
