Determination of Optimal Opening Scheme for Electromagnetic Loop Networks Based on Fuzzy Analytic Hierarchy Process

Abstract EN

Studying optimization and decision for opening electromagnetic loop networks plays an important role in planning and operation of power grids.

First, the basic principle of fuzzy analytic hierarchy process (FAHP) is introduced, and then an improved FAHP-based scheme evaluation method is proposed for decoupling electromagnetic loop networks based on a set of indicators reflecting the performance of the candidate schemes.

The proposed method combines the advantages of analytic hierarchy process (AHP) and fuzzy comprehensive evaluation.

On the one hand, AHP effectively combines qualitative and quantitative analysis to ensure the rationality of the evaluation model; on the other hand, the judgment matrix and qualitative indicators are expressed with trapezoidal fuzzy numbers to make decision-making more realistic.

The effectiveness of the proposed method is validated by the application results on the real power system of Liaoning province of China.
