Abstract

The distribution network has become more flexible due to the integration of such power electronic devices as intelligent soft switches and DC/DC converters. Flexible interconnection is gradually emerging as a key technological approach for upgrading the distribution network framework and enhancing its flexibility regulation capability. Multi-port flexible interconnection devices can achieve such functions as energy conversion and power regulation，thereby promoting the utilization and consumption of renewable energy. As for the multi-port flexible interconnect device topology proposed in this paper，the hardware-in the-loop testing research in the pre-demonstration stage is performed. First，the topology structure and each port configuration of the multi-port flexible interconnection device are introduced，and the secondary equipment architecture and hierarchical coordinated control system of the control and protection system of the multi-port flexible interconnection device are designed. Then，the control strategy of the flexible interconnection device is designed based on the grid forming control technology and，on this basis，the hardware-in-the-loop testing scheme design，including RTLAB joint debugging architecture，valve based control equipment design，is performed. Finally，the hardware-in-the-loop testing research is carried out for such typical operating conditions as charging，unlocking，step testing，islanding/grid-connection switching as well as fault-ride-through. The test waveforms confirm the reliability and accuracy of the constructed platform，providing a basis and technical support for the factory integration test and on-site commissioning of the demonstration project.
