Concentrating solar power (CSP) technologies emerged as efficient and reliable sources of renewable energy. The solar powered Dish-Stirling systems are form of CSP technology and recorded the highest solar-to-electric energy conversion efficiency. The intermittent nature of the solar irradiance creates variations in the generator rotor frequency which may cause the system to operate in undesired regions of operations (motor mode or pull-out torque). Also the unique operational characteristics of Stirling engine require an external torque and rotational motion source for the starting sequences. The power electronics and mass quantity changes within the Stirling engine are used for speed and frequency control. However various technical hurdles are associated with these two methods along with considerable reduction in system efficiency. For the start-up requirements, the induction generator installed in the Dish-Stirling system is suggested, in different works, to operate as a motor until the system reach the operating rated speed. For a large number of units of Dish-Stirling system this would create a tremendous load that indeed makes this solution infeasible. The literature has not yet provided cost-effective solutions for both issues. The continuously variable transmission (CVT) is a gear train technology that has been reported in applications for wind turbines. Due to the similar design operating characteristics between the wind turbine systems and Dish-Stirling systems, the CVT technology is adapted to be embedded in the Dish-Stirling system for frequency control during different solar irradiance levels (e.g. cloud transient) and to provide a rotational motion and torque during the start-up stage. The use of the CVT for the Dish-Stirling system application is originated in this work. Models of the thermal and gas dynamics components, mechanical components, electrical and control components are provided. The Matlab/Simulink is the software environment chosen to simulate the system dynamically and in steady state operation. Results of different variables including generator frequency, currents (in RMS values), torques generated by the prime mover, and torque of the generator are presented. The results suggest that the inclusion of the CVT transmission into the Dish-Stirling system improves the system power production performance.
