摘　　要：随着用户数量的增加,电力负荷需求也随之增加,造成了系统较大的峰谷差。而不同的发电机组,功率、容量、发电成本均不同,因此有必要对不同时间段机组负荷进行分配。使得机组在满足当前负荷需求的基础上,能够以相对较经济的方案运行。本文利用优先顺序法以及等微增率法,分别针对系统在12h和24h的负荷需求,对IEEE-RTS系统机组负荷分配进行了研究。分别得出了两个时间点最低总发电成本的运行机组类型、数量以及总的发电成本。With the increase of the number of users, the power load demand also increases, resulting in a large peak-valley difference in the system. However, different generating units have different power, capacity and generating cost, so it is necessary to distribute unit load in different time periods. On the basis of meeting the current load demand, the unit can operate in a relatively economical scheme. In this paper, the priority order method and the equal micro increment method are used to study the unit load distribution of IEEE-RTS system for the load requirements of the system at 12h and 24h respectively. The types, quantities and total generation costs of the lowest total generation costs at two time points are obtained respectively.
