This paper addresses the problem of optimally placing charging stations in urban areas.
Two optimization criteria are used: maximizing the number of reachable households and
minimizing overall e-transportation energy cost. The decision making models used for both
cases are mixed integer programming with linear and nonlinear energy-aware constraints.
A multi-objective optimization model that handles both criteria (number of reachable
households and transportation energy) simultaneously is also presented. A number of simulation
results are provided for two different cities in order to illustrate the proposed
methods. Among other insights, these results show that the multi-objective optimization
provides improved placement results.
