this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...

Recently, Brushless Cascaded Doubly Fed Induction Generator (BCDFIG) has been considered as an attractive choice for grid-connected applications due to its high controllability and reliability. In this paper, a Finite Control Set Model Predictive Control (FCS-MPC) method with active and reactive power control capability in grid-connected mode is proposed for controlling the BCDFIG in a way that...
