研究了配电网需求侧管理(DSM)方案对网损和负荷裕度的影响。采用由恒阻抗负载、恒流负载、恒功率负载和感应电机负载组成的复合负载模型对电网中的负载进行建模。这使得在分布式发电的配电网中跨所有节点应用DSM程序后，能够更准确地分析潮流和网络可负载性极限的变化。已应用的DSM方案旨在通过调整网络中的灵活需求以适应不稳定的分布式发电，并将其对上游网络的依赖降至最低，从而尽可能保持网络的自给自足运行。分析表明，转移不同的负载分量(即恒阻抗负载或感应电机)，并在DSM动作后的不同时间重新连接它们(所谓的负载回馈)对网络性能有何影响。本文使用的网络是一种改进型IEEE 33节点配电网
This paper investigates the effect of demand side management (DSM) program in distribution network on network losses and loading margin. The composite load model comprising constant impedance, constant current, constant power and induction motor loads is used to model the loads in the network. This enables a more accurate analysis of the changes in load flow and network loadability limit after applying a DSM program across all the buses in a distribution network with distributed generation. The applied DSM programme aims at maintaining as close to self-sufficient operation of the network as possible, by adjusting flexible demand in the network to the volatile distributed generation, and minimizing its reliance on the upstream network. The analysis shows how shifting different load components (namely constant impedance load or induction motors), and reconnecting them at different times following a DSM action (the so called load payback) affect the network performance. The network used in this paper is a modified IEEE 33 bus distribution network
