Abstract

Abstract : With the development of high‐voltage direct current (HVDC) projects, hybrid AC/DC power grid will be the main characteristic of China's power grid. As a result, improving the accuracy of power flow result has the important significance of the planning, operation and dispatching of the power grid. This study introduces an improved load flow calculation method, based on reactive power compensation and control strategy of the HVDC converter configuration. The proposed method deals with the effect of reactive power exchange between AC and DC grids, as well as actual situation. In the end, Jiangsu power grid is used to verify to the correctness of the method and the simulation results show the effectiveness in different operation modes of HVDC.
