New interconnections requirements for utility-connected photovoltaic systems are coming into play in several European countries, armed with the task of supporting the grid operation and stability. This approach to better integration of photovoltaic systems into the electric power system enables a larger selection of renewable energies. This paper presents the new grid code in Germany as an example of this improved integration, complemented by a brief report regarding activities currently being undertaken to ensure European harmonisation of interconnection requirements.
