针对自动发电控制(automatic generation control,AGC过程中难以把握潮流状态的问题,在安全经济调度确定的AGC机组的基点、参与因子,以及超短期负荷预报提供节点分配因子和功率因数变化规律的基础上,结合动态潮流电热耦合潮流等概念,利用实时区域控制偏差(area controerror,ACE)信号,建立了伴随AGC机组控制过程的潮流模型和算法。实际算例对所提模型和算法进行了验证,结果表明,在跟踪AGC控制过程中计算潮流非常重要,这对于跟踪输电线路温度变化,监视系统安全性能等都是有益的。
Aiming at the problem that automatic generation control (AGC process is difficult to grasp the trend of power flow conditions), based on the base point of the AGC unit, participation factor and short-term load forecasting provide node distribution factor and power factor , Combined with the concept of dynamic tidal current and thermo-coupled current flow, a real-time regional control error (ACE) signal is used to establish the power flow model and algorithm with the control process of AGC unit.Experimental results show that the proposed model and algorithm are validated. It shows that it is very important to calculate the power flow during the tracking of AGC control. This is beneficial for tracking the temperature change of transmission line and monitoring the safety performance of the system.
