The invention relates to the field of micro-grid prediction control, and discloses a micro-grid prediction control method considering internal charging and discharging of cluster electric vehicles. The method comprises the following steps: S1, inputting wind energy and basic load data of a certain place and a certain typical day, and predicting the related characteristics of each electric vehicle to be connected to a micro-grid; S2, judging whether each electric vehicle connected to the micro-grid participates in regulation or not, if not, turning to step S3, and otherwise, turning to step S4; S3, independently calculating the charging power of the electric vehicle which does not participate in regulation and control; S4, adopting a double-layer model predictive control strategy for the electric vehicles participating in regulation and control, and firstly, carrying out upper-layer charging and discharging optimization on the cluster electric vehicles; S5, based on the step S4, carrying out charging and discharging power distribution on each electric vehicle at the lower layer; S6, judging whether rolling optimization is finished or not, if so, turning to step S7, and otherwise, turning to step S1; and S7, outputting the optimal charging and discharging strategy of the cluster electric vehicles. The charging urgency of each electric vehicle is considered, and the operation pressure of the power grid is relieved.

    本发明涉及微电网预测控制领域,公开一种考虑集群电动汽车内部充放电的微电网预测控制方法:S1、输入某地某一典型日的风能和基本负荷数据,并对各待接入微电网的电动汽车相关特性进行预测;S2、判断接入微电网的各电动汽车是否参与调控,如不参与调控,转至S3,否则转至S4;S3、对不参与调控的电动汽车单独计算其充电功率;S4、对于参与调控的电动汽车采用双层模型预测控制策略,首先对集群电动汽车进行上层充放电优化;S5、基于S4,在下层对各电动汽车进行充放电功率分配;S6、判断滚动优化是否结束,如已结束,转至步骤S7,否则转至S1;S7、输出集群电动汽车最优充放电策略。本发明考虑各电动汽车的充电紧迫性,缓解了电网运行压力。
