发布时间：2019-07-29 18:10
【摘要】：针对电网运行中线路过负荷可能引发的连锁过载跳闸问题,提出一种基于灵敏度分析和潮流熵的紧急控制模型。基于模糊多属性决策法综合灵敏度、潮流熵和节点自身功率水平提出节点功率调整指标,能够将决策专家的定性分析与定量分析相结合。根据节点功率调整指标以及节点类型形成功率调整节点集和功率平衡节点集,并提出了兼顾电网的局部过负荷问题和全局运行水平的线路过负荷紧急控制优化模型,通过多轮次系统功率调整可高效完成线路过负荷紧急控制。对IEEE39节点系统标准算例和河北南网系统的仿真结果证明了模型的正确性和有效性。
[Abstract]:In order to solve the problem of chain overload tripping caused by line overload in power grid operation, an emergency control model based on sensitivity analysis and power flow entropy is proposed. Based on the fuzzy multi-attribute decision method, a node power adjustment index is proposed based on the comprehensive sensitivity, power flow entropy and the power level of the node itself, which can combine the qualitative analysis and quantitative analysis of decision experts. According to the node power adjustment index and the node type, the power adjustment node set and the power balance node set are formed, and an optimization model of line overload emergency control is proposed, which takes into account the local overload problem and the global operation level of the power grid. The line overload emergency control can be completed efficiently through multi-cycle system power adjustment. The correctness and effectiveness of the model are proved by the standard example of IEEE39 node system and the simulation results of Hebei South Network system.
