New interconnections requirements for the grid connection of PV systems are coming into force in a number of European countries, assigning a new role to distributed generators in supporting the grid operation and stability. The new approach of a better integration of photovoltaic systems into the electric distribution system enables a larger dissemination of renewable energies. This paper presents the new requirements introduced by the recently published Medium Voltage grid codes in Germany, France and Austria as examples for improved integration, complemented by an in depth analysis of the testing and certification procedures which have been developed for the verification of the compliance of PV inverters, components and whole installations.
