  • Perturb and Observe (P&O) and Incremental Conductance (INC) are the most commonly used algorithms in MPPT systems because they are simple and inexpensive. But these two algorithms are not effective when solar radiation increases or decreases rapidly and suddenly so there is a deviation of the maximum power produced. Therefore both of these algorithms are modified to improve their performance. In this study a comparison of the algorithms of P&O and INC that have been modified are Modified Perturb and Observe (Mod P&O) and Modified Incremental Conductance (Mod INC) in tracking the maximum power produced by photovoltaic. The converter used in testing this algorithm is the SEPIC converter. In the MPPT system with the Modified Perturb and Observe algorithm the average power efficiency generated reached 76,5%, whereas in the Modified Incremental Conductance algorithm the average power efficiency produced was higher reaching 79,9%.
