Integrating renewable power in the transport and distribution grids

The paper shows how Europe has successfully integrated some 70 GW of solar and a similar amount of wind power by means of regulating the access to grid for all renewable energy´s generating units. It deals with possible critical situations in the distribution grid such as island formation, overload of equipment and voltage maintenance and also addresses critical fields in the transport grid such as frequency fluctuations or sudden power drops and describes the technical and regulatory solutions: The necessary technical grid requirements have reached “state of the art”, they are implemented in the normative standards and the rules of operation for renewable power plants in the EU-countries. Though European harmonization is still at an early stage, there are no obstacles to further expansion. Finally, the presentation offers solutions to be transferred to newly developing renewable markets like Saudi Arabia.
