Abstract

The invention discloses a network power efficiency evaluation model optimization method based on a numerical inverse problem. The method comprises the following steps: extracting indexes related to the power grid efficiency, establishing an index system for evaluating the efficiency, and setting the weight of each index; establishing fuzzy mapping from the evaluation index system to the power grid efficiency, correcting the index weight by using an S-type function, and substituting the index value and the corrected weight into a fuzzy mapping function to obtain a quantitative evaluation model of the power grid efficiency; under the condition that the index value is known, building an inverse problem model for optimizing the index weight by the grid power efficiency in the evaluation model through a least square method; applying regularization to the inverse problem model to suppress numerical ill-conditioned performance, namely, a regular penalty function item is added to the inverse problem mathematical model; and solving the inverse problem model to which regularization is applied by adopting a Newton-Ravphen iterative algorithm to obtain an optimal weight. According to the invention, the grid power efficiency evaluation model is optimized through the existing simulation and experimental data, and the accuracy of the evaluation result is improved.
