Probabilistic constrained load flow based on sensitivity analysis

This paper presents a method for network constrained setting of power system control variables based on probabilistic load flow analysis. The method determines operating constraint violations for a whole planning period together with the probability of each violation. An iterative algorithm is subsequently employed providing adjustments of the control variables based on sensitivity analysis of the constrained variables with respect to the control variables. The method is applied to the IEEE 14 busbar system and to a realistic model of the Hellenic interconnected power system indicating its suitability for short-term operational planning applications.<
