Research on Prediction Technology of UHV Transmission Line in Global Energy Internet

In response to the global energy crisis, the State Grid Corporation of China has put forward the idea of global energy Internet, which focuses on using ultra-high voltage (UHV) transmission technology for power delivery across continents. Reasonable prediction of UHV transmission line can effectively assist global energy Internet scheme comparison and project decision in the early stage. Based on mathematical model, this paper selects 11 influencing factors to obtain mathematical equation of UHV transmission line. It indicates that the mathematical model obtains good results and the deviation rate between the predicted value and the actual value is less than 10%. The prediction technology of UHV transmission line in global energy Internet can meet the requirements of scheme comparison and project decision in the early stage.
