Abstract
Abstract—While distributed generation (DG) from renewable energy resources is seen as key element of future energy supply, current electricity grids are not designed to integrate a steadily increasing share of distributed generators. The hierarchical network topology was designed for unidirectional power flows and passive operation. In order to avoid excessively expensive grid reinforcements, new solutions for active grid operation will be necessary. This paper introduces a set of innovative technical measures that allow a higher DG penetration within the grid. A new control algorithm for coordinated voltage control in an active distribution grid featuring these measures is proposed. Simulation results for an application of the algorithm in an actual Austrian distribution grid segment are presented. I
