摘要
Establishing data center application scenarios based on flexible DC distribution system(FDCDS) and quantitatively evaluating the FDCDS of data center from multiple aspects are of great theoretical and practical significance to improvements in the reliability and economic efficiency of data center power supply. Therefore, this paper proposes a multi-objective comprehensive evaluation method of FDCDS for data center application scenario. Firstly, a comprehensive evaluation index system of FDCDS of data center is established from the perspectives of power supply reliability demand, investment and construction operation cost, data center scene demands, and energy saving demands. Secondly, to ensure that the determined index weight can reflect the expert experience and the objective difference of index itself, a method combining the order relation method and maximizing deviation method is used to determine the index weight, and then a multi-objective comprehensive evaluation method based on like-Gaussian distribution fuzzy membership function is proposed. Finally, the effectiveness of the proposed evaluation index and method is verified by the multi-objective comprehensive evaluation of different distribution system examples. ? 2022 Science Press.
