Decentralised Energy Management System with comprehension of fluctuated renewable energy resources

Under integration of renewable energy resources many still understand only proof procedures to connect new power plant to public grid. The existing management systems aim to observe electrical and thermal grid condition. In defined situations renewable power plants will be turned off. Another huge problem is the natural fluctuation of direct renewable energy converter such as photovoltaic and wind turbine. This paper shows a realistic future scenario how the whole potential of decentralized renewable energy resources can be exploited. The developed Decentralised Energy Management System comprises eight functional components: prognoses (wind, load), disposition, nodal load prediction, schedule planning, power system simulation, evaluation of simulation, model of decentralised power plants (dpp) and online controller, see fig. 4. Introductions on offline planning and online system are given.
