基于靈敏度和潮流熵的線路過負(fù)荷控制策略
[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.
