Research on the Calculation Method of Regional Grid Construction Efficiency and Power Demand under the Background of High Power Grid Complexity

Abstract

With the gradual development of power grid, the characteristics of power grid, such as regionalization, multi-dimensional and network complexity, have become more and more obvious. At the same time, the new round of power system reform has higher requirements for the development of power grid in all aspects. One of the key points of the reform is to achieve accurate investment in power grid, improve the efficiency of power grid construction and meet the demand of power grid construction. In this paper, the classic Analytic Hierarchy Process (AHP) is used, combined with the development situation of the power grid under the new requirements, the index system and model for the calculation of the construction efficiency and demand of the local and municipal power grid under the background of the highly complex development of the power grid are put forward. The model takes the time line of the power grid construction as the axis, through the pre-evaluation and post-evaluation of the power grid construction, the calculation of the construction situation of the regional power grid is completed. The efficiency and demand of power grid construction in different cities are analyzed. The example shows that the model can effectively identify the construction attributes of each region, reflect the construction requirements of the provincial power company system through different judgment matrix, and verify the final calculation results, optimize the construction and demand of the power grid system. The model effectively improves the operation efficiency of the power grid system, and realizes the ultimate goal of energy conservation and emission reduction.
