| 摘 要： | 提出了一种动态安全调度新算法。基于最大相容集的概念，从暂态稳定控制的工程背景出发，将可行域为空的动态安全调度优化问题扩展为在其最大相容集簇上的寻优问题。并将其转换成一个混合整数规划模型，解决了动态安全约束过强导致优化问题不可行及预防控制的经济代价过高等困难。试验算例证实了模型和方法的有效性，根据动态安全调度特点探讨了今后的研究方向。

| Abstract: | This paper presents a dynamic security dispatching method. Based on the concept of maxim um com patible set, infeasible optimization problem s are extended to the optimization problem s on its maxim um com patible set fam ily.A linear mixed integer programming model is proposed to tackle the extended optim ization problem . The extension is applied to dynam ic security dispatching problem s,and overcomes the two m ain difficulties in dynamic security dispatching research: optimization problem infeasibility due to strong dynam ic security constrains and im practical result for high costof rescheduling of generation. Test exam ple proves that the m ethod can handle problem of multi- fault scenarios effectively. L astly,the further researching directions are discussed. |
