A　comprehensive　benefit　evaluation　index　system　of　a　smart　substation　construction　project　is　constructed　from　four　dimensions　of　intelligent,　economic,　green　and　safety　benefits.　The　attribute　values　of　the　evaluation　indicators　are　the　hybrid　information　containing　linguistic　variables,　exact　numbers　and　normal　distribution　interval　numbers.　A　hybrid　multi-criteria　decision　making　model　for　hybrid　information　is　constructed　based　on　intuitionistic　fuzzy　sets　and　a　combined　weighting　method.　First,　different　transformation　rules　are　used　to　uniformly　convert　the　hybrid　information　into　the　form　of　intuitionistic　fuzzy　numbers.　Then　the　GEM-IFE　combination　weighting　method　based　on　a　cooperative　game　model　is　used　to　determine　the　comprehensive　weight　of　indicators,　and　an　improved　TOPSIS　evaluation　model　is　established　based　on　intuitionistic　fuzzy　sets.　Finally,　10　smart　substation　construction　projects　are　taken　as　cases　for　analysis,　and　this　model　is　compared　with　the　traditional　TOPSIS　method　and　single　weighting　method.　The　results　show　that　the　hybrid　multi-criteria　decision-making　model　has　good　robustness.　©　2023　Power　System　Protection　and　Control　Press.　All　rights　reserved.
