Özet

Photovoltaic PVA-solar powered electrical systems comprise different components and subsystems to be controlled separately. Since the generated solar power is dependant on uncontrollable environmental conditions, it requires extra caution to design robust tracking controllers that can handle unpredictable events to maintain dynamic source-load matching to ensure maximum power utilization at all times. In this paper, a photovoltaic (PV) solar array model is developed using Matlab/Simulink/Sim-Power GUI software environment and fully controlled using novel dynamic control strategies combining both classical PI controller and fuzzy logic controller (FLC) in a multi-loop error driven regulation. The novel multi-loop error driven FLC controller has a flexible design so that it can easily be modified and extended for controlling different dynamic systems such as Wind and Hybrid Schemes and proved very effective in stand alone Green Power utilization systems. The proposed Dual Multi Loop Control system is validated on a sample Study System Modelled using in Matlab/Simulink.
