RT21 | [Chinese] Analysis on modeling technology based on HYPERSIM of Zhangbei Flexible DC Grid

Flexible DC transmission technology has been widely used in large-scale grid-connected renewable energy consumption, regional grid asynchronous interconnection and long-distance high-capacity transmission and other fields. In order to meet the new challenges brought about by the new power system, it is urgent to develop the electromagnetic transient real-time simulation modeling technology of large-scale new energy, flexible DC and AC power grid. This presentation will introduce the example of Zhang Bei Flexible DC project, so as to discuss in detail the current problems existing in the modeling of the flexible AC-DC mixed grid, and the solution based on HYPERSIM.
