摘要

This article presents an enhanced model of a two-terminal voltage source converter based high-voltage DC system suitable for optimal power flow analysis in electric power systems. Both the back-to-back and the point-to-point voltage source converter and high-voltage DC schemes are addressed. Unlike to other proposals, the new model considers the operational constraints associated with the MVA ratings of the converters. The proposed model is implemented in a Newton-based optimal power flow approach and tested on the Baja California North 160-bus realistic power system. Simulation results show that a practically feasible optimal power flow solution can be obtained by considering the MVA converters' limits.
