“…One of the peculiar characteristics of dispersed generation system is the capability to detach from the grid and endure to provide local loads during grid interruptions. Exchanging from a grid-tied mode to a stand-alone mode is known as islanding mode [12]. The algorithm matches the magnitude and phase of the inverter voltage and the grid voltage at the time of disconnecting or reconnecting to the grid to minimize any sudden voltage change across the load.…”

This paper presents flexible control strategy of a squirrel cage induction generator (SCIG) featuring transition between stand-alone and grid-connected systems. The consistent load voltage supply in both the modes is ensured with smooth transition of the controls of standalone and grid connected modes. In the proposed technique, dc bus voltage controller of the stand-alone system is maintaining the input power same as the demand by controlling the speed. On the other hand, the same dc bus voltage controller of the grid-connected system maintains the output power at same level as input power. The transient performances of different variables of the system, during this flexible control are found to be satisfactory and THD remains within 3% throughout the study. The flexible control for both the modes is presented for the first time in available literature. The model is helpful for interfacing into wind-energy system.
