Política Ótima de Comercialização de um Microgrid de Energia Solar conectado ao Grid e a Veículos Elétricos Híbridos

We propose an optimal buying and selling policy between the microgrid and the utility grid in this paper. Through the use of stored energy in hybrid electric vehicles (PHEVs) as system states, an inventory model of stochastic dynamic programming is proposed in the formulation. The load of these vehicles is managed in a way that minimizes the buying costs of the microgrid as well as the opportunity cost of excess inventory. A numerical example illustrate the applicability of the model in a scenario when vehicles disconnect from the microgrid in the morning and connect in the late afternoon. We also consider a microgrid with solar generation peaks at noon. Finally, limitations and possibilities of future work are also discussed.
