摘要：

为准确评估不同申报模式下售电套餐的预期效益,研究了电力用户在峰谷型售电套餐中调峰响应的贡献度,并提出了一种考虑调峰响应的峰谷型售电套餐效用评价方法。介绍了峰谷型售电套餐基本概念,其主要特征在于电价随用户峰谷电量比例的下降而下降,以激励用户主动参与调峰服务。为量化调峰响应带来的不利影响,设计了电力用户调峰响应影响程度评价模型。在此基础上,综合考虑用户在履行该协议后,购电费用和调峰响应带来的不利影响,提出了一种考虑调峰响应的效用评价方法。基于2类用户实际数据构造算例得出评估结果：若不考虑调峰响应带来的不利影响,用户倾向于申报较低的峰谷电量比例系数,以降低套餐电价;然而当套餐电价降低到一定程度后,峰谷电量比例系数带来的用电限制将大幅影响电力用户正常使用需求,导致综合效用下降。结果表明,电力用户在购买峰谷型售电套餐时,必须统筹考虑峰谷电量比例调整带来的购电费用变化和用电习惯变化,准确评估调峰响应带来的不利影响,合理确定峰谷电量比例指标。

Abstract:

In order to accurately evaluate the expected benefits of electricity retail packages under different reporting modes, the contribution of power users' peak regulation responses to peak-valley power retail package was studied, and a utility evaluation method for the peak-valley power retail package considering peak regulation responses was proposed. Firstly, the basic concept of the peak-valley power package is introduced. A main feature of the package is that the electricity price it offered decreases with the shrink of peak-valley power' proportion, so users will actively participate in peak-valley regulation. In order to quantify the adverse effects of peak-shaving responses, an evaluation model to classify power users' peak-shaving responses was designed. On the basis of this, a utility evaluation method considering the variation of electricity price and adverse effects of peak-load responses is proposed. Finally, based on the data of two power users, a case study is made and the evaluation results show that users tend to declare a lower peak-valley power ratio without considering the adverse effects of peak response. However, when the price is reduced to an extent, the power restriction caused by the ratio coefficient of peak-valley electricity will greatly affect the normal use demand of power users, leading to the decline of comprehensive utility. The results show that when purchasing peak-valley electricity package, power users must take into account the changes of electricity purchase cost and electricity consumption habits caused by the adjustment of peak-valley electricity ratio, accurately evaluate the adverse effects brought by the response of peak-valley electricity ratio, and reasonably determine the peak-valley electricity ratio index.

Key words: peak-valley power electricity package, peak regulation response, comprehensive utility, peak-valley power ratio, power user, electricity consumption behavior, energy storage
