边缘智能技术在智能配电网中的应用探讨

Discussion About Application of Edge Intelligence Technology in Intelligent Distribution Networks

智能电网技术的快速发展,引入了大量的智能化设备,致使传统的云端集中式管理遇到了挑战。主动配电网用电侧具备更灵活的调节能力和负荷特性动态变化。为了更好地适应和满足多样的负荷侧主动响应,智能配电网必须提供一种可快速迭代的在线自动调度系统架构。提出一种将边缘计算技术结合人工智能的应用思路,以配电网需求响应协调控制架构为例,讨论了具体实现方式,提出“云边端”协同控制模式,在边缘节点进行负荷聚类、负荷预测以及负荷控制。最后,结合开发的试验样机做了典型应用说明。结果表明,提出的在线协调控制系统能够满足负荷侧主动调节的优化调度。

Rapid development of smart grid technology has introduced a large number of intelligent devices,and traditional centralized cloud management has encountered challenges.The user-side of the active distribution network has gained even more flexible regulation capability and load characteristics change dynamically.In order to adapt to and satisfy various active responses on the load side,the intelligent distribution network has to provide a fast iterative architecture for an automatic online dispatching system.It was proposed in this paper that the edge computing technology be combined with artificial intelligence,and a specific implementation method was discussed by taking coordination control architecture for distribution network demand response as example.Furthermore,a"cloud edge"coordinated control mode was proposed,whereby load clustering,load forecast and load control were completed at edge nodes.Finally,a typical application description was given with respect to a developed test prototype.It could be seen that the proposed online coordinated control system could satisfy optimal dispatching of active regulation at the load side.
