Target Architecture of Distribution Network Monitoring System towards Energy Revolution and Digitization

In order to adapt to the energy revolution and digitization, a new design for the distribution network monitoring system is proposed to achieve data lifecycle management. Firstly, the current practices and limitations of existing monitoring systems are presented. According to the development trend, the reconstruction strategy is presented involving three feedback local-computing loops and data interaction between distributed intelligent agents and cloud-based master station. To support the huge scale of sensed data integration and transmission, the reference framework of data interaction is established, and the main monitoring information is presented. Then some technical evolution trends towards the new architecture are described in the fields of unified model, new generation of intelligent terminal, network interconnection, edge-cloud computing and security system.
