“…where i indicates the type of PEVs, j is number of PEVs, L j is the trip path for jth PEV, and L max i is the rated length path that each type of PEVs can trip [29]. In this paper, the selected values for parameters 1 , ˛2 and ˛3 are 0.85, 0.8, and 0.75, ˇ1, ˇ2 and ˇ3 are 0.15, 0.2 and 0.25; and L 1 , L 2 and L 3 are 40, 50, 60 miles, respectively.…”
