Abstract

Abstract:

This paper focuses on the construction of an experimental platform for edge computing, and first builds the three-layer experimental platform architecture. Then, the functions of each physical part of the experimental platform and the communication environment are designed. Subsequently, targeting the core technical problems of software and hardware of edge computing, a specific and feasible simulation solution is proposed around the operation and control needs of distribution networks. Finally, taking edge-side local voltage control as an example, the operation scenarios are constructed based on various aspects of the experimental platform to illustrate the functional feasibility and reliability of the platform.

Key words: digital distribution network, digitalization, edge computing, experimental platform
