能量与信息融合的电力物联网技术

电力物联网是建立以新能源为主体的新型电力系统的关键技术之一。电力线载波物联网(PLC-IoT)作为能量与信息融合的物联网技术的成功实例，不仅能够利用现有电力线资源进行数据传输，还能提高电网深度感知的能力，适合作为电力物联网网络层的通信方式之一，并促进电网与通信网的深度融合。首先介绍了电力物联网的发展概况，分析了能量与信息融合的物联网技术的可行性和关键问题，并结合PLC-IoT的关键技术和应用优势，探讨了PLC-IoT在电力行业的应用场景和发展方向。最后提出了建设更普遍的多能流多信道泛在能源物联网的愿景。

Power internet of things technology with energy and information fusion

The power internet of things is one of the key technologies to establish a new-type of power system with new energy as the main power source. As a successful case of internet of things technology with energy and information fusion, PLC-IoT can use existing power line resources for data transmission and improve the deep perception of power grids. It is suitable for use as the communication method at the power internet of things network layer and can promote deep integration of the power grid and communication network. This paper first introduces the current development of the power internet of things, analyzes the feasibility and key issues of the internet of things technology with energy and information fusion, and discusses the application scenarios and development directions of PLC-IoT in the power industry by analysis of its key technologies and application advantages. Finally, a vision of establishing a universal multi-energy flow and multi-channel ubiquitous energy internet of things is proposed.
