Hybrid DC transmission systems are prone to DC current oscillations as the parameters of constant DC current controller increase, an oscillation suppression strategy based on virtual resistance is proposed. This strategy generates an additional vol

The grid-forming (GFM) control technology is instrumental in enabling converters to provide frequency and voltage support response akin to synchronous generators, thus bolstering the stability of the new power system. Nonetheless, a notable c

The flexible DC transmission system is connected to the island grid, so the control mode needs to be changed according to the AC topology. In the process of grid-connected and island operation conversion, there are phenomena such as excessive dis

Direct-hanged energy storage of voltage source converters (VSCs) on the DC side can be applied to active or reactive power grids. It has the advantages of peak shaving and valley filling, reducing wind and photovoltaic power curtailment. Given

Distribution of landslide is controlled by various causative factors that have different impacts on the occurrence of landslide in different regions. Using one single model to build the hazard assessment is not enough to fully reflect the spatial dif

TPMS is consistently described in the functional representation (F-rep) format, while modern CAD/CAM/CAE tools are built upon the boundary representation (B-rep) format. To solve this issue, translating TPMS to STEP is needed, called TPMS2STEP. This
