Implementation of Fuzzy-PID Based MPPT for Stand Alone 1.75 kWP PV System

摘要

Maximum Power Point Tracking (MPPT) is used to find and maintain the maximum power output from photovoltaic array due to weather changing. MPPT works by observe the power located at peak or not, by add disturbance signal. In this paper, We design fuzzy-PID MPPT charge controller for 1.75 KWP photovoltaic system with stand alone configuration. The array consists of 6 modules @280kWP in series configuration. Output power is compared with existing MPPT charge controller. Result shows that the proposed design increases PDC 14% compare to existing MPPT charge controller.
