| Abstract: |
| With the power generation of distributed renewable energy and the medium-and low-voltage DC networking technologies have been rapidly developed, the future distribution network will inevitably evolve into a complex hybrid AC&DC form, and its operation regulation technologies will face many new challenges. Based on the analysis of the development demand of operation regulation technologies for high proportion distributed renewable energy integrated hybrid AC&DC distribution network(HR-HDN),three scientific issues of operation regulation technologies for HR-HDN are extracted, which takes the cooperation of multiple types of controllable equipments, highly interactive and market-oriented demand of source-network-load-storage as the main line of research. In addition, the operation regulation technology framework of HR-HDN is proposed from four aspects of stability control, active fault prevention and recovery, auxiliary regulation of power market mechanism and “platform+data” digital integrated regulation. Finally, the future development of operation regulation key technologies for HR-HDN is prospected. |
