Solution for Connecting Regenerative Electric Drive Systems to the Grid

Abstract:

In this paper the topology of the grid-connected regenerative electric drive systems (REDS) and the performances of the integral state feedback current controller of the front-end three-phase power inverter are presented. The proposed control was successfully implemented by the author on a quasi direct AC-AC converter with Proportional-Integral current controllers and the simulation test has been performed for the modified integral state feedback current controllers based on the Matlab/Simulink software. The comparative results between the actual current controller topology and that of the conventional PI current controllers of the AC-AC power converter are reported. Moreover, the solution presented in this paper adds supplementary benefits to power system besides the conventional state feedback control: the designed input filter assures zero steady state error and an adequate component is added for the dynamic rejection of the load disturbance. Because it uses the integral component, the control structure has robust capabilities to disturbance actions.
