摘 要:针对断面潮流控制模型复杂度高、非线性强导致的求解困难问题,提出了基于节点综合灵敏度的断面功率越限控制方法。首先建立关键断面功率越限控制模型,尽可能提升调整速度的同时减小调整代价及调整量;为快速求解该模型,考虑断面越限程度,对传统灵敏度进行改进,提出节点综合灵敏度的概念,量化表征控制节点有功功率对断面功率的影响程度;然后基于节点综合灵敏度对控制节点进行筛选和排序,并确定控制量的大小。最后,基于IEEE 39节点系统进行仿真验证,表明所提方法可以有效控制断面越限量,并使得系统调整量最小。In order to deal with the solution difficulty caused by the high complexity and strong non-linearity of the section power flow control model,this paper proposes a section power out-of-limit control based on the integrated sensitivity of the nodes.Firstly,the critical section power out-of-limit control model is established to improve the adjustment speed as much as possible while reducing the adjustment cost and amount;In order to solve the model more quickly,the traditional sensitivity is improved by considering the degree of the cross-section overloading.The concept of the node comprehensive sensitivity is proposed to quantify the influence of the active power of the control nodes on the cross-section power;Then,the control nodes are screened and sorted based on the comprehensive sensitivity of the nodes,determining the sizes of the control quantity.Finally,based on the IEEE 39 bus system,the simulation results show that the method is able to effectively control the cross-section overloading and minimize the system adjustment.
