Zusammenfassung

Decentralizing energy systems require renewable energy sources to assume a higher degree of system responsibility. Concerning voltage stability and reactive power management, wind and PV parks connected to 110 kV grids are technically capable of providing reactive power. A controllable and situation- dependent feed-in depending on the respective situation could not only reduce grid losses in the distribution grid, but also facilitate a flexible reactive power exchange with the transmission grid in order to support the voltage stability of the system. In this paper, a two-step approach is presented to estimate the nodal reactive power potential and to estimate cost savings arising from a flexible reactive power exchange between transmission and 110 kV grid. Results are deducted for a simple test grid as well as for the German transmission grid
