Integration of 50 % wind power in a CHP-based ... - Ea Energianalyse

162 Discussion8.4.3. The importance of optimization modelingThe model is based on the West-Danish energy system. Although many simplificationshave been made on various parameters, ranging from energy prices to physical and environmentalcharacteristics, the modeled approximation of the impacts are of great relevanceto the evaluation of a future Danish power system with 50 % wind power, in thatthe results reflects the fundamental dynamics of the current system. The formulatedunit commitment model has been a good tool for answering the stated objectives.Despite of a few suggested modifications, the unit commitment model of this project hasbeen successfully designed with the ability to provide results that highlight the problemscontained by the 50 % wind power, as well as to assess the potentials of turbine bypassand heat pumps (economically as well as environmental). Meanwhile, by focusing mainlyon significant system characteristics (e.g. technical properties of large central units), thefinal detail-level of the model has been well balanced between, on one hand, being highlyaccurate (and compute heavy), and on the other, being very simple and less accurate.
