According to local resource conditions to determine a viable energy utilization program, the use of energy prices, energy demand system parameters such as initial investment, life-cycle cost analysis of possible options to obtain energy priorities. Area-based annual hourly load demand, the study area energy characteristics. Comprehensive energy use characteristics and regional energy characteristics, the development of complex energy utilization program, the life cycle cost analysis of different energy matching mode to determine the proportion of all kinds can be assumed for energy.
