Abstract

This paper discusses a multi-terminal VSC HVDC system proposed for integration of deep sea wind farms and offshore thermal and nuclear platforms in to the grid onshore. An equivalent circuit of the VSC in synchronous d-q reference frame has been established and decoupled control of active and reactive power was developed. A three terminal VSC-HVDC was modeled and simulated in MATLAB/SIMULINK software. Voltage margin method has been used for reliable operation of the HVDC system without the need of communication. Simulation results show that the proposed multi-terminal VSC-HVDC was able to maintain constant DC voltage operation during load switching, step changes in power demand and was able to secure power to passive loads during loss of a DC voltage regulating VSC-HVDC terminal without the use of communication between terminals.

Keywords: HVDC, multiterminal HVDC (MHVDC), offshore wind power, voltage control, and wind power generation
