Abstract :
Photovoltaic (PV) system is one of the energy generation systems and produces direct current. The PV output is depending on solar irradiation and temperature. The arrangement of PV cells in series or in parallel, known as PV array. Maximum Power Point Tracking (MPPT) techniques like Incremental Conductance (Inc Cond) with fixed step size is used to extract maximum power from a PV system. Inc Cond control algorithm is compared with a MPPT PI controller. DC DC Boost converter steps up and regulates the PV output voltage to get a usable form of DC voltage. PV cell single diode model with a series and parallel resistances and a DC DC boost converter are developed and implemented, MPPT control algorithms are developed, compared and simulated in MATLAB/SIMULINK. Results are presented and discussed.
