4. Conclusion

A simple, compact and cheap power converter system has been designed to deliver power from wind farms either to an isolated load or to the grid application. Its modeling analysis and design procedure have been presented. The SPV panel was used for the main source of rotor injunction and it reduced the power drawn by the rotor from the grid. For future use, the excess power from the SPV panel can be stored in the battery. The harmonics of stator voltage can also be reduced using an NPC inverter. The DFIG controller inverter and boost regulator have been designed An Integrated Hybrid Renewable Energy System Based on Doubly Fed Induction Generator… DOI: http://dx.doi.org/10.5772/intechopen.81083

for low settling time with a very low overshoot and a good dynamic response. The complete system is simulated using Typhoon HIL® software. As stated earlier, both of the two energy sources were exactly modeled in Typhoon HIL® to forecast their real characteristics. Future work includes a low cost true MPPT controller and optimization of the integration of this MPPT into a standard PV panel.
