摘    要:现有自动发电控制(AGC)容量确定方法只考虑了安全性,因而造成计算结果偏大,而已有的优先顺序法只考虑用一种指标进行AGC机组选择。文中利用统计分析方法,通过考察发电机组AGC执行历史数据来确定不同AGC容量需求对应的概率;并在AGC运行费用中计入了因调节容量不足所造成的惩罚费用,将AGC运行费用最低点的概率所对应的AGC容量作为系统所需AGC调节容量。同时,提出了可考虑多种指标的改进型优先顺序法,该方法可综合考虑性能和价格两方面的因素。通过对某省实际电网的算例分析,验证了所提出的方法的可行性和实用性。

关 键 词:电力市场  自动发电控制  容量确定  机组选择

Abstract:The result is tilted toward the big side because the previous method of AGC requirement determination only considers the security, and the present merit-order method considers only one kind of index to select generating units to perform AGC function. The proposed method in this paper, using statistical analytical method, determines the corresponding probability of different AGC capacity requirement through analyzing the historical performance data of AGC unit, takes into account penalizing charge as a result of regulating capacity lack and takes the AGC capacity corresponding to the probability of the lowest AGC function charge as the needed AGC regulating capacity. And an improved merit-order method, which can consider many indexes, is proposed. This method can consider the two aspects of the performance and the price. The example applied to a practical system indicates that the proposed method is feasible, valid and practical.
Keywords:electricity market  automatic generation control (AGC)  requirement determination  unit selection
