COMPARISON OF MPPT ALGORITHMS FOR PV SYSTEM USING SINGLE DIODE AND THEVENIN EQUIVALENT MODELS

Maximum Power Point Tracking (MPPT) algorithms are significant in PV systems due to they reduce the PV panels number that necessary to reach the target output power, lowering the PV array expense. This research gives a simulated comparison of two essential MPPT techniques, incremental conductance (IC) and perturb and observe (P&O) utilizing single diode and Thevenin comparable models. The essential parameters involving voltage, current, and power output were traced for both methods using a DC-DC boost converter. The results of stimulation revealed that for the two tracking algorithms the single diode module gives higher output power in comparison with the Thevenin equivalent model but for the IC algorithm the Thevenin equivalent model gives less output signals ripple.
