摘  要:为解决集中式优化控制无法应对大量电动汽车(EV)随机接入微电网引起的功率波动问题,提出了基于分布式模型预测控制(MPC)的微电网控制策略。首先,建立EV参与需求响应的可行时间模型来描述EV的充放电事件,评估各时戳下EV个体参与需求响应的可能性。其次,基于MPC得到每辆EV的最优出力计划,利用碳配额机制并结合实时电价,引导EV用户积极参与需求响应。最后,通过算例分析表明,所提出的微电网控制策略可有效应对EV随机性引起的微电网波动性问题,并能根据实时更新的状态信息调整充电/放电计划,保证微电网稳定经济运行。In order to solve the problem of power fluctuation caused by a large number of electrical vehicles(EVs)randomly connected to a microgrid,the paper proposes control strategy for the microgrid based on distributed model predictive control(MPC).Firstly,a feasible time model of EVs participating in demand response is established to describe EV charging and discharging events,and the possibility of EVs participating in the demand response at each timestamp is evaluated.Secondly,the optimal output plan of each EV is obtained based on MPC,and the carbon quota mechanism is combined with real-time electricity price to guide EV users to actively participate in the demand response.Finally,an example analysis shows that the proposed control strategy for the microgrid can effectively deal with the volatility of the microgrid caused by EV randomness,and can adjust the charge/discharge plan according to the real-time updated status information,ensuring the stable and economic operation of the microgrid.
