A comprehensive evaluation system and evaluation method for the adaptability of low-voltage AC-DC hybrid distribution network

As energy transformation and the promotion of new power systems gain momentum, the low-voltage AC/DC mixed distribution network has emerged as the preeminent wiring form for distribution networks.To harness the advantages of low-voltage AC/DC mixed distribution systems in providing reliable power supply, it is imperative to develop an assessment method that adapts to different environments. This paper delves into the comparison between low-voltage AC/DC mixed distribution networks and traditional distribution networks. It identifies representative indicators from economy, power supply stability, and power quality to establish an evaluation system for low-voltage AC/DC mixed connection systems. Subsequently, the entropy weight method is applied to calculate the objective weight and Hierarchical analysis method is used to calculate comprehensive weight. By employing the comprehensive fuzzy evaluation method, membership level indices are established. The indices are graded in examples, and combined with the previously calculated comprehensive weight, the fuzzy comprehensive rating score of the scheme is derived. This enables the identification of the optimal adaptive solution.
