Voltage Regulation Control with Adaptive Fuzzy Logic for a Stand-Alone Photovoltaic System
European Journal of Electrical Engineering
Electronic circuits suitable for converting, controlling and conditioning electrical energy in solar applications are required to ensure efficient use of the solar system. This paper proposes a stand-alone system consisting of a Maximum Power Point Tracking (MPPT) algorithm and a fuzzy logic based voltage controller for a photovoltaic application. The fuzzy logic-based intelligent algorithm MPPT controls the DC-DC boost converter to find the best Maximum Power Point (MPP) with speed and
... h speed and accuracy without steady state oscillations under variable methodological conditions (irradiance and temperature). The fuzzy logic-based voltage controller is designed using the T-Standards and the standardization process to improve transient control performance. Voltage Regulation Control with Adaptive Fuzzy Logic for a Stand-alone Photovoltaic System is designed and simulated in the MatLab/Simulink environment. The results show that the fuzzy controller effectively resolves system voltage instability by keeping the DC-DC buck converter voltage constant despite variable weather and load conditions.
