DC-link voltage

This paper presents a new control strategy to reduce the fluctuation of DC bus voltage for a backto-back PWM converter in a DFIG wind turbine systems. DC-link voltage Feed-forward compensation control strategy for DFIG’s RSC and GSC converter is proposed to limit the fluctuation range of the dclink voltage. The dynamic performances of the DFIG are compared with the traditional control method.

This paper proposes the Finite control set Model Predictive Control (FCS-MPC) with delay compensation for three-phase threelevel T-Type NPC inverter (T-Type NPC) of grid-connected photovoltaic systems (PV). The proposed FCS-MPC controls the objectives: current tracking control, DC-link capacitor voltage balance, the reduction of switching frequency to ensure issues of the power quality and improve the efficiency of grid-connected of PV system.
