Abstract

In order to eliminate the impact of inter-regional differentiation of development demand on the objective evaluation of the development level of smart grid, this paper establishes the evaluation model of weight modification, transmission mechanism and combination of subjective and objective weights. Firstly, the Analytic Hierarchy Process method is used to calculate the weights of evaluation indices of effect layer and then the indices of development demand are used to modify the weights of them. The association analysis and the correlation coefficient are used to establish the weights conduction coefficient between the effect level and the base level. Then the subjective weights of the indices of the base layer are calculated. The objective weights of the indices of the base layer are obtained by using the entropy method. The subjective weights of the base layer and the objective weights obtained by the entropy method are averagely calculated, and the comprehensive weights of the evaluation indices of the base layer are obtained. Then each index is scored according to the weights and index values. Finally, the model is used to quantitatively inspect the level of development of smart grid in specific regions and make a horizontal comparison, which provides a useful reference for the development of smart grids. The relevant examples verify the correctness and validity of the model.

Summary

Introduction

Based on an integrated and high-speed bi-directional communication network, smart grid is designed to be reliable, safe, economical, efficient, and environment-friendly through advanced sensing and measurement technologies, equipment technologies, control methods, and decision support system technologies. Key features of it include self-healing, motivating and engaging users, defending against attacks, providing power quality that meets 21st century user needs, allowing access to a variety of power generation forms, activating power markets, and optimizing asset applications for efficient operation. In recent years, some areas have combined smart grids with intelligent transportation to build new smart cities [1]. As an important part of the energy internet, it has drawn wide attention from all of the world and has become a new trend in the development of the world’s power grid [2,3,4].
