摘要 考虑到超短期负荷预测偏差的情况下,以购电费用变化量最小为目标函数重新调整发电计划,从而导致电网可用输电能力(ATC)发生变化.为快速而准确测得ATC的值,提出利用连续潮流或最优潮流方法得到ATC的基值;利用有功灵敏度快速而实时得到ATC的变化值,从而获得发电机计划调整后的ATC值,为市场条件下电能传输容量提供参考依据. Because of super short - term load forecast＇ error, ATC is changing with the adjustment of the generation scheduling by the object function that purchasing charge is least. In order to obtain the accurate value of ATC, this paper utilizes continuation power flow or optimal power flow to calculate the basic value of ATC and utilizes active power sensitivity to get the value of ATC. Thus the real value of ATC which supplies the reference to ATC is known.
