摘要
针对大量电动汽车(electric vehicle,EV)接入微电网带来的稳定性及经济性问题,同时为充分发挥EV的移动储能特性,提出一种在动态电价机制下考虑EV动力电池移动储能特性的微电网调度模型。首先,建立含EV动力电池、风电、光伏、柴油发电机组的微电网数学模型;其次,在综合考虑分布式电源发电成本、EV用户成本、电池损失成本、环境成本的基础上,计及与主网电能交易、新能源补贴等多项收益,制定考虑新能源出力的EV动态电价机制;最后,以微电网运行成本、EV用户成本、环境成本最低为目标函数,建立计及EV移动储能动态电价机制的微电网调度模型。为验证所提方法的有效性,通过YALMIP和GUROBI建立并求解所提最优调度模型。仿真结果表明,相比传统控制方法,微电网总运行成本降低了16.96%。
According to the stability and economy of the microgrid caused by large-scale of electric vehicles(EVs),and in order to give full play to the mobile energy storage characteristics of EVs,it proposes a microgrid scheduling model considering the energy storage characteristics of EV power batteries mobile under the dynamic electricity price mechanism.Firstly,the mathematical model of the microgrid including EV power battery,wind power,photovoltaic,and diesel generator sets are established.Secondly,on the basis of comprehensive consideration of distributed power generation costs,EV user costs,battery loss costs,environmental costs,and multiple benefits such as electric energy trading income,new energy tariff subsidies,etc.,and a dynamic electricity price mechanism for EVs considering the output of new energy is established.Finally,an objective function with the lowest operating cost of the microgrid,the cost of EV users and the environmental cost is established,and a microgrid dispatching model based on the dynamic electricity price mechanism of EV mobile energy storage is proposed.In order to verify the effectiveness of the proposed method,the proposed optimal scheduling model is established and solved by YALMIP and GUROBI.The simulation results show that compared with the traditional control method,the method proposed can reduce the total operating cost of the microgrid by 16.96%.
