Analysis of the Influence of HVDC Transmission on Power Grid Loss

Line loss is one of the important technical and economic indexes of power system. In order to effectively overcome the line loss of power system, a novel hybrid integration method of power flow and sensitivity analysis is designed. Taking Qingyu project as an example, this paper analyzes the influence of DC system control parameters on the operation characteristics and line loss of AC / DC hybrid transmission system, and the research results verify the effectiveness of the new method.
