PV SYSTEM INCREMENTAL CONDUCTANCE MPPT METHOD APPLIED FLYBACK CONVERTER UNDER VARIABLE TEMPERATURE AND IRRADIANCE
Abstract
This paper proposes to Photovoltaic (PV) system with Incremental
Conductance (IC) MPPT (Maximum Power Point Tracking) method applied
to Flyback converter under variable temperature (25ᵒC-50ᵒC) and
irradiance (600W/m2-1000W/m2). The power and voltage of PV panels are
nonlinear, they depend on environmental conditions such as temperature
and irradiance, changing environment conditions lead to change the power
of PV panels, and also change the MPP (Maximum Power Point) of PV
panels. There is unique MPP of PV panels at different environment
conditions. To operate PV panels at MPP there are many MPPT methods in
literature, these methods are differ in same ways like; accuracy, speed,
cheapness, easy to implement..etc. In this study IC MPPT method is used
because of easy to implement and its good result under variable weather
conditions. PV systems are consist of PV panels and DC-DC converters, as a
DC-DC converter Flyback converter is used to regulate voltage of PV panel.
The maximum power point of PV panel, used in this study, is 75W and the
accuracy of MPPT method > 98%, efficiency of system > 94%. The system
constructed and analyzed in MATLAB/Simulink and This paper is supported
