Research on charging and discharging control strategy of electric vehicles and its economic benefit in microgrid

As the concept of the microgrid and the hierarchical partition dispatch is proposed, and electric vehicles as new elements will be included in the microgrid and its economic dispatch control, the load model and economic benefit of electric vehicles have become a hot research topic. Firstly, considering the characteristics of electric vehicles, two kinds of charging and discharging strategies were formulated, and corresponding load model of two strategies were established. After that, an microgrid economic dispatch model with electric vehicles and new energy is established, and the priority method is used to solve it. Finally, a case is carried out to study the economic dispatch problem of a renewable microgrid with electric vehicles. The study shows that the priority method can effectively solve the economic dispatch problem of the microgrid, and it can improve the economic benefit of the microgrid to apply orderly charging and discharging control.
