This paper presents comparative performance between Maximum Power Point Tracking-Fuzzy Mamdani (MPPT-FM) and MPPT-Fuzzy Sugeno (FS) methods as controller on Photovoltaic (PV) output power using Dynamic Voltage Restorer-Battery Energy Storage-PV (DVR-BES-PV) system connected to three phase three wire (3P3W) distribution network. The combination of DVR-BES-PV system using two methods is used in order to mitigate voltage sag/swell and harmonics on load bus. The PV is used as an alternative DC voltage source to charge BES when its capacity decreases and provides active power needed to compensate for sag/swell. In nine sag/swell disturbances scenario, MPPT-FM is able to give better performance in percentage of sag/swell on load voltage than MPPT-FS. In 90% voltage sag, MPPT-FM is able to result percentage of voltage sag on load bus of 5.759% smaller than MPPT-FS of 5.770%. Then, in 190% voltage swell, MPPT-FM is able to result percentage of voltage swell on load bus of 0.892% smaller than MPPT-FS of 1.064%. Both methods are also able to result percentage of sag/swell on load voltage under IEEE 1159. In voltage sag, MPPT-FM is able to result an average Total Harmonics Distortion (THD) of load voltage higher than MPPT-FS. Otherwise in voltage swell, MPPT-FM is able to result an average THD of load voltage smaller than MPPT-FS. In 90% voltage sag, MPPT-FM is able to result average THD of load voltage of 10.32% higher than MPPT-FS of 10.14%. Otherwise, in 190% voltage swell, MPPT-FM is able to result average THD on load bus of 1.594% smaller than MPPT-FS of 2.087%. The average THD of load voltage using MPPT-FM/MPPT-FS in nine voltage swell disturbances scenario on source bus, is smaller than voltage sag and it has met limit of IEEE 519. This research is simulated using Matlab/Simulink environment.
