The large-scale grid connection of renewable energy is accompanied by problems such as insufficient voltage support capability and weakened disturbance resilience. For multiterminal DC sending system, commutation failure faults may lead to overvoltage issues, threatening the safety and reliability of power grids. To better assess transient overvoltage levels, this paper proposes a feature extracti...Show More
The power router (PR) has been widely used to improve the utilization of renewable energy sources (RES). The intermittent and random nature of RES inevitably increases the fault probability of PR. However, none of the existing methods can realize the fault diagnosis of PR. To address this issue, a novel fault diagnosis method based on transfer learning and gated recurrent unit fully convolutional ...Show More
The safe and stable operation of power system faces serious challenges such as the variability of operation mode and the lack of disturbance attenuation ability. To achieve the accurate voltage stability evaluation and provide reliable reference for emergency control, this paper proposes a transient voltage stability margin evaluation method based on deep residual network (ResNet) and gated recurr...Show More
