STEADY-STATE POWER FLOW CALCULATION IN A HYBRID HVAC/VSC-HVDC GRID

Abstract

Voltage source converter high voltage direct current (VSC-HVDC) transmission technology is increasing its share in AC transmission due to important advantages such as independent P and Q control and lower harmonics. Nowadays, this technology is used to connect far-away remote offshore wind-power plants to mainland networks. VSC-HVDC is the main actor in developing the future multi-terminal DC grids and supergrids. This paper proposes a sequential algorithm to calculate the steady state power flow in a specific hybrid HVAC/VSC-HVDC grid which is a solution that is going to be seen in the early stages of the planned supergid.
