Abstract

Abstract: AC power distribution network is now the main form of the distribution network, which failed to cover three distribution form, AC, DC and AC-DC hybrid power distribution. The subjectivity of exiting distribution network assessment method is strong Thus, this paper proposes a set of assessment system to evaluate the comprehensive benefit of medium and low voltage distribution network, which includes five aspects:technology, power supply reliability, economy, sociality and environment protection, and each aspect is further subdivided into a number of specific indicators. Meanwhile, the comprehensive evaluation method based on fuzzy entropy weight is adopted to assess the comprehensive benefit of typical distribution mode of AC, DC and AC-DC hybrid power distribution network. The proposed method was verified by a few examples.

Key words: medium and low voltage distribution network, AC-DC hybrid power distribution mode, assessment index system, the evaluation method based on fuzzy entropy weight, comprehensive benefit
