Generation capacity selection of the natural gas-fired CCHP system

Presents conventional ways to determine the generation capacity. According to the annual hourly load, obtains the generation capacity with a project in Shijiazhuang by the two methods of fixing power based on cooling/heating load and fixing power based on electricity load. The results show that the annual hourly load is important not only for determining the generation capacity, but also for forecasting the operating cost; appropriate power-on hours are the key to determine the generation capacity.
