“China's energy transformation is facing new challenges, and the energy consumption characteristics of the entire "source grid load" chain are not yet clear. Therefore, research on energy loss analysis and prediction of the new power system's AC-DC conversion process has been carried out, providing theoretical support for the transformation of the power system to improve quality and efficiency. A scenario analysis system for the development of AC-DC hybrid power systems has been established, exploring the topic of energy loss prediction throughout the entire chain, and providing solutions for reducing power system energy consumption and improving operational efficiency.”
