基于两阶段交叉控制的电动汽车集群功率调节方法及系统
摘要：
本发明涉及一种基于两阶段交叉控制的电动汽车集群功率调节方法及系统，包括以下步骤：1)建立电动汽车集群有功无功混合控制的并网模型，确定对电动汽车集群进行有功无功优化控制的目标函数及其约束条件；2)建立对电动汽车集群进行有功优化的目标函数及其约束条件；3)将电动汽车集群的充电时段划分为若干功率控制时段；4)对有功功率控制的目标函数进行求解，得到有功功率优化结果；5)建立对电动汽车集群并网无功优化的目标函数及其约束条件；6)对无功优化的目标函数进行求解，得到无功功率优化结果；7)重复步骤4)～6)，在各功率控制时段内对电动汽车集群进行有功优化和无功优化。本发明可广泛应用于电动汽车集群功率调节。
摘要（英）：

The present invention relates to a method and device for electric car cluster power regulation based on two-stage cross control. The method comprises the following steps: 1) establishing a grid-connected model of electric car cluster active and reactive mixed control, and determining an objective function for performing active and reactive optimization control of an electric car cluster and constraint conditions thereof; 2) establishing an objective function for performing active optimization of the electric car cluster and constraint conditions thereof; 3) dividing the charging duration of the electric car cluster into a plurality of power control durations; 4) performing solution of the objective function for active power control, and obtaining an active power optimization result; 5) establishing an objective function for performing grid-connected reactive optimization of the electric car cluster and constraint conditions thereof; 6) performing solution of the objective function for reactive optimization, and obtaining a reactive power optimization result; and 7) repeating the step 4), the step 5) and the step 6, and performing active optimization and reactive optimization for the electric car cluster in each power control duration. The method and device for electric car cluster power regulation based on the two-stage cross control can be widely applied to the power regulation of the electric car cluster.
