Integrating dispersed generation into the Danish power system - present situation and future prospects

Since the early 80s a huge amount of dispersed generation (DG) has been implemented into the Danish power systems. Today the Danish system has a share of 18.5% electricity consumption produced by wind turbines and 26.5% produced by combined heat and power units (CHP), of which the biggest part is installed in the western part of Denmark. The paper shows the technical measures as well as utilization of market mechanisms applied by the Danish system operator, Energinet.dk, to handle the challenging situation of safe and reliable system operation. Future prospects with respect to the internationally growing wind power capacity and respective need for a market for ancillary services are presented
