Economical energy supply of business parks

The present work uses a linear optimization framework for energy system extension and unit commitment to investigate key cost determinants for medium scale business parks. The optimization is done for the energy carriers electricity, heat and cold together and yields strong sector coupling in the cost optimal energy system. An on-site combined heat and power plant (CHP) proves to be economically very beneficial, with a high electrical efficiency being of special importance. Under current market conditions the use of solar photovoltaics (PV) can be economically feasible for such business parks.
