Research Progresses and Prospects on Application of Edge Computing in Power System Supply-demand Interaction

供需互动通过电力系统需求侧与供应侧的信息交互可构建灵活的能源调控体系,是实现电力系统高效经济运行的可靠保障,是新型电力系统的重要特征。随着电力物联网的不断发展,电力系统供需终端所产生的数据量急速上升,传统的云计算架构难以适应海量数据处理需求的增长。作为一种新兴的计算范式,边缘计算通过边缘侧具备一定计算能力的设备在数据源附近就近处理部分数据,具有低时延、高效率和分布式的特点。通过将边缘计算应用到电力系统供需互动领域,可以有效提高供需互动的效率,提升数据的安全性,增强互动的灵活性。文中首先总结了边缘计算在电力系统中的发展现状,然后阐述了边缘计算应用于供需互动领域的关键技术,最后对边缘计算与供需互动在未来进一步的研究前景进行了展望。

Supply-demand interaction can build a flexible energy regulation and control system through the information interaction between the demand and supply sides of the power system,which is a reliable guarantee for efficient and economical operation,an important feature of the new power system.With the continuous development of the power Internet of Things,the amount of data generated by power systems'supply and demand terminals is rising rapidly,and the traditional cloud computing architecture can hardly adapt to the growth of massive data processing demand.As an emerging computing paradigm,edge computing processes part of the data near the data source through devices with specific computing capabilities at the edge,which has the characteristics of low latency,high efficiency,and distribution.Applying edge computing to the field of power system supply-demand interaction can effectively improve the efficiency of interaction,enhance the security of data,and strengthen the flexibility of interaction.The paper first summarizes the development of edge computing in the power system,then describes the key technologies of edge computing applied to the field of supply-demand interaction,and finally provides an outlook on the future research prospects of edge computing and supply-demand interaction.
