The aim is to integrate wind and solar electricity generation to create a steady supply of energy. The fluctuations in wind and solar contributions are compensated by the demand flexibility on the consumer side, according to Wolfram Krause, head of the project.
If turbine output does not correspond with the forecast output, the virtual power station adjusts the consumption of the cooling facility accordingly, explains Ulrich Focken from Energy & Meteo Systems.
Energy & Metea is one of the six partners in the project alongside large regional energy company EWE, its consultancy subsidiary BTC, and research institutes Fraunhofer Allianz Energie, Offis and Öko-Institut.
The project coordinates the operation of eight AN Bonus ( now Siemens) 2MW turbines, the Midlum 0.7MW biogas plant and the cool store with two units totalling 500kW of cooling capacity.
