AbstractThe increasing generation and flexible demand at a local level enable the development of a local market structure, in which its participants could trade with each other and/or with other market structures. Therefore, demands such as electric vehicle charging stations could take advantage of the flexibility in charging electric vehicles to participate in the market. In this sense, this paper intends to explore the optimal charging of electric vehicles to enable the participation of charging stations in the local energy market, considering that energy transactions in the market are constrained by the physical limits of the network. A mathematical model is proposed to represent the operation of prosumers and charging stations, as well as their commercial interaction in a local market structure. Charging stations' interests in the market are represented by an aggregator. The objective of the proposed model is to minimize energy purchase costs from the aggregator, with the coordination of charging as the control variable. The impact of this control was analyzed considering using the IEEE 33-node distribution system, and the results obtained show that this coordination enabled a better participation of the charging stations in the local market.
