中文摘要：
电池储能电站（battery energy storage station,BESS）由于受到成本高和储能应用技术因素的限制,难以进行大规模商业应用。首先将BESS应用于辅助服务电力市场,在设定辅助服务的提供者、提供方式、交易规则的情况下,研究了BESS参与基于风险消弭的风电辅助服务的经济性,建立了BESS参与风电辅助服务综合经济效益模型。然后针对模型求解,计算了储能电站的投资回报率、投资回收期等经济指标,评估了该储能电站的效益优劣。最后量化分析了各种影响因素的改变对BESS收益水平的影响。
英文摘要：
Currently, because of high cost and some technology problems, it is difficult for battery energy storage station（BESS） to be commercially applied in large-scale. Research of BESS＇s economy is more urgent than before and has more guiding significance. In this paper, BESS is applied to auxiliary service power market. In case of setting auxiliary service providers, providing methods and transaction rules, economy of BESS participation in wind power auxiliary service based on risk elimination is studied and comprehensive economic benefit model of BESS participation in wind power auxiliary service is established. Solving this model to calculate some economic indicators of energy storage power plant, including investment return and payback period, storage power station＇s benefits are estimated. Effects of various factors on BESS income level are quantitatively analyzed. Research result has reference value in background of rapid development of current energy storage.
