Maximum Power Point Tracking of Dish Stirling System in Partially Shadow Condition Using Fuzzy Logic Controller Based on PSO Algorithm

This paper presents a novel approach based on fuzzy logic controller to track optimum operational point of dish-stirling system in uniform irradiance condition. The proposed method considers all details of system including thermo mechanical and electrical aspects of dish stirling system where previous studies use a simple model to assess this issue. Multi parallel dish stirling systems have more extremum operation points in partially condition system. Hence, this study utilize fuzzy logic controller to find global maximum power point tracking of system when all aspects of system are taken in to account. Finally In order to validate the proposed method, a comprehensive case study has been conducted on dish stirling systems. Simulation results show the accuracy of the proposed method in different conditions in comparison with previous methods.
