摘要
基于最大可调裕度和暂态安全代价的概念 ,给出了考虑暂态稳定性的负荷经济分配模型及其算法。该方法用高阶泰勒级数快速仿真故障轨迹 ,在求得暂态能量的同时计算暂态稳定裕度对控制变量的灵敏度 ,并用于负荷分配。试验算例证实了该方法的有效性。由于暂态稳定问题的非线性 ,如何处理多故障场景和合理分摊暂态安全费用有待进一步研究。
Based on the conceptions of maximum regulation margin and transient stability cost, this paper gives the mathematical model and solving method for the economic load dispatching, which takes the transient stability into account. In this method, higher Taylor series extending method is employed to simulate fault trajectories, and the sensitivities of transient stability margin to the control parameters are calculated for load dispatching when the transient energy has been obtained. A test example proves the effectiveness of this method. However, due to the non-linearity of the transient stability problems, how to handle the multi-fault scenarios and how to apportion the transient stability cost reasonably need further investigations.
