考虑EV充放电意愿的园区综合能源系统双层优化调度

随着电动汽车的普及度越来越高，工业园区的电动汽车用户日益增多，其充放电行为对园区综合能源系统规划和运行带来极大挑战。本文提出了考虑电动汽车充放电意愿的园区综合能源系统双层优化调度。首先基于动态实时电价、电池荷电量、电池损耗补偿、额外参与激励等因素建立充放电意愿模型，在此基础上得到改进的电动汽车充放电模型；然后，以园区综合能源系统总成本最小和电动汽车充电费用最小为目标建立双层优化调度模型，通过KKT条件将内层模型转化为外层模型的约束条件，从而快速稳定的实现单层模型的求解；最后，进行仿真求解，设置3种不同场景，对比了所提模型与一般充放电意愿模型，验证了文中所提引入EV充放电意愿模型的园区综合能源系统双层优化调度的有效性和可行性，具有一定的经济效益。

Two-layer optimal scheduling of park integrated energy system considering the Charging and Discharging Willingness of Electric Vehicles

With the increasing popularity of electric vehicles, the number of electric vehicle users in industrial parks is in-creasing, and their charging and discharging behaviors pose great challenges to the planning and operation of the park''s comprehensive energy system. This paper proposes a two-tier optimal scheduling of the park''s comprehensive energy system considering the charging and discharging willingness of electric vehicles. Firstly, a charging and discharging willingness model is established based on factors such as dynamic real-time electricity price, battery charge capacity, battery loss compensation, and additional participation incentives, and an improved electric vehicle charging and discharging model is obtained on this basis; A two-layer optimal scheduling model is established with the goal of minimizing the charging cost of the car, and the inner model is transformed into the constraints of the outer model through the KKT condition, so as to quickly and stably solve the single-layer mod-el; finally, the simulation solution is performed, and three different In this scenario, the proposed model is com-pared with the general charging and discharging willingness model, and the effectiveness and feasibility of the two-tier optimal scheduling of the park''s comprehensive energy system introduced in the EV charging and dis-charging willingness model proposed in this paper is verified, which has certain economic benefits.
