风电供热系统的能源利用率和经济性分析
|
摘要
为降低北方风电场的弃风率,结合北方冬季的供暖需求,风电供暖系统作为解决方案被提出。本文选取了目前国内外存在的与风电相关的4种供热系统方案:风能—电锅炉、风能—地源热泵、风光电互补供热系统、风电光热混合供热系统,并对其能源利用率、供暖能力和经济性进行了比较分析。结果表明,风能—地源热泵供热系统相较其他3个系统具有优势,但总体而言,采用风电供暖系统的供暖价格仍远远高于传统燃煤供暧,风电供暖项目的推动仍需国家政策上的支持。
In order to decrease curtailment rate of wind farm in north China,heating system driven by wind power is proposed as a solution with consideration of great local demand for heating in winter.In this paper,four heating systems related to wind power are analyzed in aspects of energy performance,heating capacity and economic consideration respectively.The results show that the wind power driven heat pump system(WDHP) is the best in these aspects.However,utilization of all wind power driven heating systems would lead to higher heating price compared with traditional heating system by using coal-fired boiler.The promotion of wind power driven heating system still needs support from government policy.
