Challenges and Integration of PV and Wind Energy Facilities from a Smart Grid Point of View

The increasing share of renewable energies, especially solar photovoltaic (PV) and wind, will require coordinated efforts in order to adapt them to the future grid infrastructure. For that, the communication between electronic devices is a key technology. Although there is an international communication standard with IEC 61850 and the required models for energy systems are already specified, they face an existing heterogeneous system structure in reality. Therefore a migration concept is required in order to integrate today's fragmented devices. Standardised communication and certified products are required to ensure security, safety and reliability in a diversified future grid infrastructure.
