Application of binary connection number-projection grey target decision theory in power system emergency capability evaluation

An evaluation method based on the binary connection number-projection gray target decision theory was introduced, and it was applied to the evaluation of power grid emergency capacity, due to the diversification of indicator data types in the evaluation of power grid emergency capacity. Firstly, a basic indicator system for power grid emergency capability evaluation with multiple data types was established through research and analysis. Secondly, the established multi-type indicator data system was processed using binary connection number theory to realize the unity of data composition form in order to facilitate subsequent analysis and calculation. Then, the weights division model of the indicators based on the network hierarchy analysis method was used to determine the weights of the power grid emergency capacity indicators, taking into account the inherent relationship between power grid emergency capacity indicators. Finally, the projected gray target decision model was used to determine the level and ranking of emergency capabilities of the object to be evaluated. Analysis results of an example show that this method can realize the processing of mixed indicator data, and effectively complete the evaluation and sequencing of the emergency capabilities of the objects to be evaluated, which is operable and feasible.
