Highway Charging Station Operator Pricing Considering Distributed Renewable Generation Resources

As the electric vehicle charging demand for highway travel increases, the charging operation is gradually becoming a significant challenge for highway charging station operators. Distributed renewable power generators could satisfy the charging demand by providing clean energy for charging stations. In this paper, a charging price-setting scheme for highway charging station operators is formulated. We model this scenario as a mixed-integer quadratic programming problem, aiming to maximize profits while achieving spatial and temporal shifting of EVs charging loads to consume renewable energy (e.g., photovoltaic and wind power). The numerical case study shows that highway charging station operators adopting the proposed method can effectively promote renewable energy consumption and boost their profits.
