Abstract

With the rapid development and wide application of new energy, new materials and power electronic technology, as well as the rapid development of the national economy and the continuous progress of production technology, users have higher and higher requirements for the quality of services provided by the power industry. Therefore, in order to improve the energy efficiency level of the distribution network, it is necessary to carry out quantitative evaluation and analysis of the investment benefits of the power grid in the stage of power grid planning and construction. In this paper, a method for evaluating the grid structure of DC distribution network based on AHP is proposed, and combined with different application scenarios of DC distribution network, the advantages of ring topology and radial topology of DC distribution system under different conditions are verified. The evaluation method proposed in this paper can quantitatively evaluate the system investment benefit in multi-level and multi-dimensional, and has good practicability.
