MetaPV was the first project world-wide that demonstrated the provision of electrical benefits from photovoltaics (PV) on a large scale. Additional benefits for active grid support from PV were demonstrated at two sites: a residential / urban area of 128 households with 4 kWp each, and an industrial zone of 31 PV systems with 200 kWp each. The enhanced control capacities to be implemented into PV inverters and demonstrated were active voltage control, fault ride-through capability, autonomous grid operation, and interaction of distribution system control with PV systems. A detailed technical and economic assessment of the additional services from PV was carried out. The role of PV in an area fully supplied by renewable sources was assessed.
