Generalized power transmission control of VSC-based multi-terminal HVDC systems for offshore wind farms integration

摘要

In this paper, a generalized power transmission control method is developed for voltage source converter (VSC)-based multi-terminal HVDC systems. The droop characteristics of the multi-terminal HVDC system are used to determine the power supplied by each sending end. Three different modes of operation are employed to control the power distribution among the receiving ends. The generalized control schemes are applied to a seven-terminal VSC-based HVDC system and simulated using Matlab/Simulink platform to validate the proposed concept.
