Sensitivity studies on the cost of electricity of hybrid power system combining wind farm with gas turbines

详细讨论了大型风电场与燃气轮机组成的互补发电系统发电成本的主要影响因子及其对系统的敏感性。通过对互补发电系统发电成本理论公式的研究,推导了互补系统中各项影响因子相对于发电成本的数学方程和影响尺度,得到了影响发电成本几个关键的影响因子。通过采用敏感性分析原理,对这些主要的影响因子在不同变化条件下对互补发电系统发电成本的影响进行了详细的分析与讨论,提出降低系统发电成本的可行性措施及其努力的方向,为在新疆地区实现这种互补发电系统提供经济分析上的基础。

this paper discussed the sensitivity studies on cost of electricity of a novel hybrid power system composing a large - scale wind farm and several small gas turbine power plants in Xinjiang region, China. According to analyze the theoretical cost of electricity equation for hybrid power system, the equations and influence scales of each affecting factors on cost of electricity were derived in detail. Several key affecting factors were found. In terms of the sensitivity study principle, the influence of each key affecting factor on cost of electricity were analyzed and dis- cussed in detail under different values. The direction and feasible methods to decrease the cost of electricity of hybrid power system were presented. The analysis results provided the economic foundation to apply this type of hybrid power system at Xinjiang region.
