针对交直流混联电网线路过负荷影响因素较多导致线路运行特征难捕捉、难以实现精准控制的问题,提出基于云边协同的过负荷协调控制方法.建立过负荷状态数学模型,采用解耦算法求解不同程度过负荷情况下电力参数增量值并进行特征提取,将其作为云边协同算法的云计算参照值,获得同时符合功率最佳、能耗最小以及避免切负荷要求的协调控制参数,实现协调控制.实验结果表明:云边协同方法在盲区约束下可以准确检测盲区以外的所有节点,未出现漏检现象;光伏、风电出力的节点功率变化明显高于正常节点,节点过负荷控制效果较好.
Coordinated control method based on cloud-edge coordination for AC/DC hybrid power grid line overload
Aiming at the problem that many factors affect the formation of AC/DC hybrid power grid line overload,which makes it difficult to capture the line operation characteristics and achieve accurate control,a coordinated overload control method based on cloud-edge collaboration was proposed.The mathematical model of overload state was established,and the decoupling algorithm was used to solve the incremental values of power parameters under different degrees of overload and conduct feature extraction further.By employing it as the cloud computing reference value of cloud-edge collaborative algorithm,the coordinated control parameters that simultaneously meet the requirements of optimal power,minimum energy consumption and load shedding were obtained to achieve coordinated control.The experimental data prove that the cloud-edge collaborative method can accurately detect all nodes out of the blind area under the constraint of blind area,without missing detection.The changes in node power of photovoltaic and wind power output are significantly higher than those of normal nodes,showing the better overload control effect over all three types of nodes.
