“…The Double fed induction generator (DFIG) fed to stand-alone load [7] or grid [8] is also available with this converter. The DFIG is the suitable option for sites even with lower wind speed [9]. By integrating battery energy storage system (BESS) in DFIG, power supply remains invariant w.r.t.…”

This paper addresses the supply of power to the stand-alone load at constant voltage and constant frequency (CVCF), from a variable source distributed generation system. The inherent problem of having a fixed output from a variable input is prominent in all of the distributed generation systems, run by uncertain renewable sources like wind. This paper proposes a topology to maintain output load voltages and frequency during changes in both input torque and load perturbation. The control is designed for both the generator side and load side converters, connected as a back-to-back converter with one dc link capacitor. The voltage across dc link capacitor is maintained at a desired level by power flow control through the generator side voltage source converter (VSC). The proposed three-stage controller technique for the generator side converter is analysed and tested in all operating conditions. The outer most dc link voltage error is passing through the controller is generating the speed reference of the speed controller. Then the inner loop current controller follows the speed controller. The load side VSC is controlled to produce a constant voltage at the output of the load side filter. The stand-alone system has successfully been tested in the simulation environment. It is found to be capable of maintaining input power level to the demand, even with 50% increment in load and 50% increment in input torque. These dynamic responses of the variables are found to be satisfactory throughout the operation.

Control of a stand‐alone squirrel cage induction generator‐based distributed generation system with variable linear, nonlinear, and unbalanced loads is developed in this paper. The combined control developed in the work is using both the load and machine side converter to meet the required objectives. The control structure is intended to get rid of the harmonic component for the duration of nonlinear loading, and to confiscate the negative (backward) sequence component during unbalance loading. The magnitude and frequency of output voltage are maintained during these conditions, as well as with step increment in linear load. A back‐to‐back converter is used to implement the combined control in this work. The control algorithm of generator side converter is to match the input power level with the demand. The major operations performed with the control covers (a) 100% increment of linear load, (b) 47.2% unbalanced load, and (c) complete shift to nonlinear load.
