Comprehensive microgrid planning and design evaluation system based on OTFN-AHP

The invention discloses a comprehensive microgrid planning and design evaluation system based on an OTFN-AHP (optimized triangular fuzzy number analytic hierarchy process), and belongs to the technical field of electric information planning. An evaluation method comprises the steps that 1) a microgrid planning and design evaluation index system is determined; 2) computation models of microgrid evaluation indexes and reasonable and practical non-linear membership function models of the indexes are provided, so that quantized values of the indexes are obtained; 3) the traditional analytic hierarchy process and a fuzzy mathematic theory are combined and optimized to form the OTFN-AHP; 4) the fuzziness of an ordering vector is removed by utilizing a centroid method variable according to preference of a decision maker; 5) relative weights of the indexes are solved by nonlinear planning according to the ordering vector; and 6) an advantage and disadvantage degree of a microgrid is determined according to the quantized values and the weights of the indexes; and an evaluation report of the micogrid is output. The evaluation system can make scientific and objective evaluation on microgrid planning and design schemes in different structures, so that the evaluation system provides a reasonable reference for the decision maker, and has very high actual instruction significance.
