A novel sequential power-flow model for hybrid AC-DC systems

This paper represents the study of integrated AC-DC Newton Raphson power flow modelling of Multi-terminal HVDC (M-HVDC) systems. Some electrical parameters are specified to control the HVDC system in Power Flow Modelling. A set of specified parameters is known as the control strategy. The number of control strategies increases with the increase in the number of DC terminals. It is observed that the power flow convergence is affected by the control strategy. In this paper, sequential method is used for integrated AC-MTDC power flow analysis. Numerous case studies are conducted with the IEEE-30 bus test system in MATLAB software.
