基于灵敏度和潮流熵的线路过负荷控制策略
Control strategy for line overload based on sensitivity and power flow entropy
摘要
Abstract
To solve the problem of line overload which may cause cascading trip-outs of transmission lines when the power system is servicing, an emergency control model is established based on sensitivity analysis and power flow entropy. Indicator of power adjustment is proposed using fuzzy multi-attribute decision making method which can combine qualitative analysis with quantitative analysis of decision-making expert on basis of overall consideration of sensitivity, power flow entropy and the bus power level. Bus set of power adjustment and power balance can be formed with indicator of the bus power adjustment and the bus type, and an optimization model for line overload emergency control is proposed, which takes into account the local grid overload problems and the global operation level of power system. The model can efficiently adjust line overload emergency control by multiple rounds. The validity and efficiency of this method have also been verified by simulation results of IEEE 39-bus standard system and Hebei South network system.关键词
