Abstract :

A new isolated wind hydro hybrid generation system, employing a DFIG driven by a variable speed wind turbine and a SCIG driven by a constant power hydro turbine are feeding three phase four wire local loads. The system mainly uses a rectifier and a PWM controlled IGBT based VSC with a BESS at their DC link. The main objective of the rectifier is to convert the AC power generated by the wind system to DC and the control algorithm for the VSC is to control the magnitude and the frequency of the system load voltage. This system has the capability of bidirectional active and reactive power flow, by which it controls the magnitude and the frequency of the load voltage. Here pitch angle control is used to achieve MPT. Wind turbine, hydro turbine, MPT controller, and a voltage and frequency controller are modeled and simulated in MATLAB and different aspects of the proposed system are studied for various types of loads, and under varying wind speed conditions. The performance of the proposed system is presented to demonstrate its capability of MPT, voltage and frequency control, harmonic elimination, and load balancing using MATLAB Simulink.
