Ali AU - Mohanad H. Mahmood PY - 2020 VL - 38 IS - 4 part (A) Engineering SP - 478 EP - 490 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - This paper presents a modified maximum power point tracking algorithm(Modified MPPT) for PV systems based on incremental conductance (IC)algorithm. This method verified with the dynamic irradiance and suddenchange of irradiance, the comparisons with conventional methods, forexample, the perturbation and observation (P&O) and Modifiedperturbation and observation (Modified P&O) were performed. Aphotovoltaic (PV) panel was simulated and tested usingMATLAB/Simulink based on PV panel at Power Electronics Laboratory.The results show that this method capable to find the maximum powerpoint (MPP) under dynamic behavior faster than ( P&O) and ModifiedP&O). Reduced oscillation of MPP indicates enhanced efficiency,providing maximum power transfer to load.
