Abstract

In power system, spinning reserve is one of the important indicators of power system security. Regarding spinning reserve as an important factor, spinning reserve cost has been appropriated highly. This paper proposes a method for decreasing spinning reserve cost using demand respond (DR) program. The effect of DR is focused on the aspect of decrease effect of spinning reserve cost. In order to present the effect of DR, demand-price elasticity matrix is used in this paper. DR program is modeled N-period time-of-use (TOU) program, which is one of the most important economic methods in Demand-side Management (DSM). The changed load is considered two sides of DR effects, which are load curtailment and load shift. Using the changed load after DR, spinning reserve cost is recalculated. Case study is conducted on the RBTS IEEE with six buses. For the TOU program, it is assumed that parameters of time period partition consist of three time periods. Spinning reserve cost is calculated from local marginal price (LMP) and capacity price (CP) of 24 hours a day.
考虑需求响应效应的纺纱储备成本评价
在电力系统中,旋转备用是电力系统安全的重要指标之一。纺纱储备作为纺纱储备的重要因素,纺纱储备成本占有很高的比重。提出了一种利用需求响应程序降低纺纱备用成本的方法。DR的作用主要集中在降低纺纱储备成本方面。为了体现DR的影响,本文采用了需求价格弹性矩阵。电力需求侧管理(DSM)中最重要的经济方法之一是对n期分时电价(TOU)方案进行建模。变化的负荷被认为是DR效应的两个方面,即负荷削减和负荷转移。利用DR后负荷的变化,重新计算纺丝备用成本。以具有6个总线的RBTS IEEE为例进行了案例研究。对于分时电价方案,假设时间段划分参数由三个时间段组成。根据当地24小时的边际价格(LMP)和产能价格(CP)计算纺纱储备成本。
