Operation and control of grid integrated hybrid wind-fuel cell system with STATCOM

This paper presents control and operation strategy of a grid connected hybrid wind-fuel cell and STATCOM based energy sources. A dynamic model for the hybrid system is developed using Matlab/Simpower. The hybrid system consists of a doubly fed induction generator (DFIG), direct drive permanent magnet synchronous generator (PMSG), directly connected self-excited induction generator (SCIG) and a solid oxide fuel cell (SOFC). Controllers for the energy sources are implemented. A static synchronous compensator (STATCOM) is used to enhance the system performance during grid disturbances and faults. Extensive simulations have been performed and results show that the hybrid system can operate properly during normal and abnormal conditions. The STATCOM improves the transient voltage stability and therefore helps the wind turbine generators and fuel cell system to remain in service during grid faults.
