Abstract

The increasing requirements upon the operation of the transmission systems may make necessary a possible future assistance by the wind farms and their operation using new energy management concepts which enable advanced control strategies. Contrary to conventional power plants, onshore wind farms normally feed into the meshed distribution grid. To be able to control wind farms according to the fixture requirements of the transmission system, the characteristics of the subordinated distribution grid must be considered. Because of the meshed structure of the distribution grid, a simple allocation of these distributed onshore wind farms to one wind power plant, feeding into one transmission grid node, is not possible. A wind farm, connected to the distribution grid, may influence two or more transmission grid nodes. For operating wind farms in a meshed grid according to the future requirements of the transmission system, the influence of each wind farm to a grid node of the transmission system must be known. For this purpose, so called Influence Factors are calculated, to determine the effects of a wind farm to one specific grid node. By using the Influences Factors, the wind farms in the meshed distribution grid can be controlled as one large (virtual) wind power plant.
