Comprehensive Evaluation on Economic Performance of Flexible Substation Power Distribution Technology based on BP Neural Network

Abstract

With improvement of energy utilization level, the effective way of power distribution becomes a key research focus. The traditional rigid power transformation is featured in low transformation efficiency and serious power loss, while the power distribution technology based on flexible substation could exactly solve this problem. This paper, aiming at technical performance, economic benefits, environment impact, policy factors, selects system suitability, transmission efficiency, operational reliability, system transient characteristics, costs, investment efficiency, natural environment impact, social environment impact, and policy influence as evaluation indexes, designs five technical and economic evaluation grade and establishes fuzzy comprehensive evaluation system in combination with analytic hierarchy process (AHP), fuzzy mathematics and BP neural network to analyze the technical economic performance of AC/DC power transformation technology based on flexible substation, and provide references to subsequent project with example verification.
