摘要: |
针对大量多维异构的电网数据引起的存储压力、计算延迟和云边通信问题,提出了一种基于Edgex Foundry的配电网无功电压云边协同控制方法。首先,感知配电网10 kV侧的电网数据,构建了“边云”、“边边”协同控制模块与配电网无功电压信息交互模型,基于多种通信协议建立云边数据传输通道。然后,部署了面向配电网无功电压的云边协同控制模型,构建了基于Edgex Foundry的配电网无功电压“云-边-端”集中-分布式协同控制架构,实现云边协同架构与十五区图控制策略交互融合。最后,基于仿真验证了云边协同控制方法可以降低计算时延,缓解云端计算和存储压力,实现在云边协同控制中母线与支线整体联控、异常支线局部单调两种调控模式的深度融合,为实现配电网无功电压云边协同控制提供了技术支撑。 |

Abstract: |
There are problems of storage pressure, calculation delay and cloud side communication caused by a large number of multi-dimensional heterogeneous power grid data. Therefore a cloud edge collaborative control method of reactive power and voltage in a distribution network based on Edgex Foundry is proposed. First, this paper obtains the power grid data on the 10 kV side of the distribution network, builds a collaborative control module for “edge cloud” and “edge” and a reactive power and voltage information interaction model of the distribution network. It establishes a cloud edge data transmission channel based on multi protocols. Second, the cloud edge collaborative control model oriented to distribution network reactive power and voltage is deployed. The "cloud edge end" centralized distributed collaborative control architecture for distribution network reactive power and voltage based on Edgex Foundry is constructed. This implements interactive integration of cloud edge collaborative architecture and a fifteen zone map control strategy. Finally, based on simulation verification, the proposed control method can reduce computational latency, alleviate cloud computing and storage pressure, and achieve deep integration of two control modes in cloud edge collaborative control: the connection of the bus and branch line and the local monotony of the abnormal branch line. This provides technical support for realizing the cloud edge collaborative control of reactive power and voltage in distribution networks. |
