摘要

需求响应一般分为基于电价与激励两种模式，采取需求响应的目的是降低峰时段负荷，减少运行风险。研究的重点是构建包含负荷控制的分时电价负荷模型，分析同时采用负荷控制激励模式与分时电价两种需求响应措施后负荷变化对电网可靠性的影响，从不同角度分析两种模式下配电网运行情况，并提出一种新的通过负荷曲线聚类来计算配电网在动态负荷下的可靠性方法。通过引入改进的k-means聚类算法对不同需求响应模式下的负荷曲线聚类，得到负荷概率模型，结合蒙特卡洛模拟方法来计算不同负荷水平下最终的配电网可靠性指标，分析了在需求响应不同模式下的负荷变化对配电网可靠性影响。算例结果表明，需求响应措施能提高系统可靠性，且包含负荷控制激励的分时电价比单一措施下的可靠性更高。

Abstract

The demand response(DR)

which is adopted to decrease peak load and operational risk

is generally divided into electricity price based DR and incentive based DR. The focus of this research is to construct a time-of-use load model that contains load control and analyies the impact of load changes on power system reliability by using two kinds of DR measures

that is incentive mode of load control and time-of-use electricity price

power grid reliability

which analyzes the two operation modes of the distribution networks from different perspectives. Furthermore

a new method of calculating the reliability of distribution network under dynamic load by load curves clustering is proposed. By introducing the improved k-means clustering algorithm

the load probability model on different DR load curve is obtained. The reliability indices of distribution network under different load levels are calculated by Monte Carlo method

and the influence of DR on the reliability of distribution network is analyzed. The results of the example show that the demand response measures can improve the system reliability

and the time-of-use electricity price including the load control is more reliable than the single measure.
