Abstract: The present invention relates to an optimal load curtailment calculating method based on Lagrange multiplier and an application thereof in power system reliability assessment, wherein the calculating method comprises the following steps: inputting all system states to be analyzed for reliability assessment and establishing corresponding optimal load curtailment models; classifying the optimal load curtailment models according to Lagrange multiplier to obtain several sets; and solving the optimal load curtailment models in each set by using Lagrange multipliers to obtain an optimal load curtailment corresponding to the system state. The core of the present invention is to establish Lagrange-multiplier-based linear functions between the optimal load curtailment and the system states, and the iterative optimization processes of the traditional optimal load curtailment calculating method are substituted with the simple matrix multiplications.
