Research on the Security Gateway Design in Local Area Access Network in Smart Grid

The implementation of the dual carbon goals and the construction of a new energy-based power system integrate energy and power systems with internet technology. The aim is to build an intelligent, clean, and low-carbon energy internet with electricity as the core. To achieve this goal, real-time measurement feedback and dynamic parameter adjustment are necessary. Digital sensing technology is applied to provide comprehensive information support and ensure the stable operation of the power grid. The design of the integrated communication gateway device aims to achieve the interconnection of the local power network with high security. This paper proposes a top-level design of the gateway for the smart grid's local access network, supporting integrated communication protocols such as Lora, Wapi, and HPLC. In addition, software design based on Docker technology is introduced to realize the power service application.
