由于风能、太阳能等间歇性发电资源的整合，供电量将出现前所未有的波动。电力零售商可以根据供给侧的波动来调整电力需求，从而在一定程度上解决需求与供应的匹配问题。必要的技术基础设施，如用于这种所谓的需求响应（DR）的高级计量基础设施已经取得了进展。然而，人们对其经济层面知之甚少，迫切需要进一步努力切实量化其财政影响。为了实现这一目标，我们导出了一个优化问题，该问题最小化了电力零售商的采购成本，以控制需求响应的使用。利用历史数据进行评价，成本波动率降低7.74%；峰值成本下降14.35%；零售商的支出可以显著降低3.52%。(C) 2013 Elsevier Ltd.版权所有。
Due to the integration of intermittent resources of power generation such as wind and solar, the amount of supplied electricity will exhibit unprecedented fluctuations. Electricity retailers can partially meet the challenge of matching demand and volatile supply by shifting power demand according to the fluctuating supply side. The necessary technology infrastructure such as Advanced Metering Infrastructures for this so-called Demand Response (DR) has advanced. However, little is known about the economic dimension and further effort is strongly needed to realistically quantify the financial impact. To succeed in this goal, we derive an optimization problem that minimizes procurement costs of an electricity retailer in order to control Demand Response usage. The evaluation with historic data shows that cost volatility can be reduced by 7.74%; peak costs drop by 14.35%; and expenditures of retailers can be significantly decreased by 3.52%.
