发电重新调度是提高静态和动态安全性的一种经济有效的方法。本文提出了一种改进的发电机组重新调度公式，并提出了一种迭代求解方法。所提出的方法可用于辅助操作员消除潜在的稳态不安全、动态不安全或它们的组合。稳态安全是由众所周知的(n-1)准则建立的，该准则处理输电线路的热极限。动态安全的定义是，在电力系统每条输电线路两端可能发生的任何意外情况下，维持系统的暂态稳定。该方法的一个吸引人的特点是，它是可靠的、现实的和易于理解的，因为该方法通过积分过程来检查动态安全性。最后给出了一个36机200节点实际电力系统的仿真结果。
Generation rescheduling is a cost-effective way to enhance steady-state and dynamic security. The paper presents an improved formulation for generation rescheduling and develops an iterative solution procedure. The proposed method can be used to assist operators to eliminate potential steady-state insecurity, dynamic insecurity, or their combination. Steady-state security is established by the well known (n – 1) criterion which deals with thermal limits of transmission lines. Dynamic security is defined in such a fashion that transient stability of the system is maintained under any of the contingencies which may occur at each end of every transmission line of a power system. An attractive feature of the proposed method is that it is reliable, realistic and easy to understand since dynamic security is checked in the method by an integration procedure. Simulation results of a 36-machine 200-node practical power system are demonstrated.
