A Control Architecture and Application Example of Low- and Medium-Voltage Distribution Network Adapted to Distributed Resource Access

Under the goal of carbon peaking and carbon neutrality, distributed resources are connected to the distribution network on a large scale, and the source, network, load and management of the distribution system have changed significantly, facing a series of new problems, which are highlighted in the digital control system, among which the existing distribution automation technology can no longer meet the growing demand for digital control of the distribution network. In this paper, we propose a control architecture for low- and medium-voltage distribution networks for different application scenarios such as centralized regulation and control of distributed resources and microgrid group cooperation, and verify it by application examples.
