大规模风电接入的综合经济性评估
|
摘要
大力发展风电已成为我国的能源战略,对未来的经济发展起到关键作用。不同地区经济发展水平、电源电网结构、用电成本和电价水平均存在差异,量化评估风电接入后的综合经济性有助于指导不同地区风电的规划和建设。本文提出了一种大规模风电接入的综合经济性评估方法,分别从6个维度进行了分析,包括系统运行成本、煤耗与排放、常规机组利用小时数、风电补贴成本、电网公司运营收益以及煤电上网电价。最后,以某省级电网为例,评估该区域大规模风电接入下的综合经济性,验证了该评估方法的有效性。
Developing wind power is becoming the national energy strategy and will play an important role in economic development. Since there are differences in economic development, power grid structure, power consumption cost and electricity price level in different regions, finding a way to quantitatively evaluate comprehensive economy after wind power integration is helpful to guide wind power planning and construction. This paper proposes a comprehensive economy evaluation method from six aspects, including system operation cost, coal consumption and emission, conventional unit utilization hours, wind power subside cost, operating benefit of power grid company and coal fire plant electricity price. Then, taking a provincial power grid as an example, the comprehensive economy with large-scale wind power integration is evaluated, and the effectiveness of this method is verified.
