Model Predictive Control Based Coordinated Voltage Control for Offshore Radial DC-connected Wind Farms

In this study, a coordinated voltage control strategy based on model predictive (MPC) is proposed for offshore radial DC-connected wind farms. Two modes are designed in strategy. the economic operation mode, farm controller generates optimal active power references as well bus of medium-voltage collector turbine (DCWT) systems and high-voltage DC/DC converters, where goal to minimize losses inside ensure that voltages within feasible range, all while tracking references. main objective deviations from rated voltage. With MPC, constraints can be explicitly represented optimization problem considering dynamic response DCWT system. addition, sensitivity coefficient calculation method farms developed improve computational efficiency. Finally, with 20 turbines used demonstrate performance
