As concentrated dish (CSP) using Stirling engines (SEs) become more dominant as a renewable and usage power source. Importance of model and simulating these systems is growing to study its performance under different operating states. In this study, for contributing (CSP) energy harvesting studies, we implemented a Stirling engine simulation block connected with an electrical generator which controlled by a PID controller under MATLAB/SIMULINK. It models and study the thermomechanical performance of SE and electric generator. The model’s domain extends from the solar energy (constant temperature in our model) to thermal, mechanical, and output electrical energy, helping to study system relations through subsystems. It is a non-linear model, that utilized to study transient and dynamic phenomena, and a complete system operation process can be simulated, from start-up to full power state. The detailed model and simulation results are discussed in this paper. It can be said that there are no helpful components for SE modeling studies, and the present literature studies are developed for special systems not for general purposes.
