MetaPV is the first project world-wide that will demonstrate the provision of electrical benefits from photovoltaics (PV) on a large scale. Additional benefits for active grid support from PV will be 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 are 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 is carried out. The role of PV in an area fully supplied by renewable sources is to be assessed. The work covers 3 phases. In the first phase, the demonstration is prepared for the specific demonstration zones. The PV side (inverter) and the network side will be both addressed. Small and large PV inverters for residential and industrial applications, which both can provide additional benefits for electrical network operation, will be developed. On the network side, adapted concepts for grid planning and operation of distribution networks with large amounts of PV generation will be developed. In the second phase, based on the development and suggestions of phase one, two pilot demonstrations will be carried out and evaluated. The first one will demonstrate the active contribution of PV for increasing power quality and security of the system operation in a residential area. In the second one, security of power supply and autonomous operation will be demonstrated in an industrial zone. The third phase covers communication with stakeholders that will take place from the beginning of the demonstration phase. The project results will be disseminated and communicated to the stakeholders, the scientific community and to the local public. The demonstration will allow for successful replication in other grids in Europe.
