    Abstract

    This paper proposes a decentralized coordinated voltage control scheme (DCVCS) for voltage-source-converter high voltage direct current (VSC-HVDC) connected wind farms based on the Model Predictive Control (MPC) which regulates the voltage profile across the wind farm network within the feasible range by optimally coordinating the VSC and wind turbines (WTs). Firstly, the centralized voltage control problem based on the MPC is formulated to minimize voltage deviations and reactive power output fluctuations of WTs. Secondly, the decentralized solution methodology based on Alternating Direction Method of Multipliers (ADMM) with fast convergency is used to solve the MPC problem in a decentralized manner without losing the optimality of the primal problem. A wind farm with 64 WTs was used to validate the effectiveness and optimality of the proposed DCVCS.
