| Abstract: | Steady-state mathematic model of VSC-HVDC for power flow calculation is established.Four variables about steady-state operation status of VSC are affirmed,and correction equations for solving ac-de system are also deduced.Alternate iteration algorithm which is applies to power flow calculation of ac-dc power system including VSC-HVDC is presented.By calculating power flow of modified EPRI-7 bus test system,the validity and efficiency of the model and algorithm for the power flow calculation are verified. |
