MPPT Control Design of PV Generator Supplied DC Motor-Pump System Based on ABC Algorithm
Authors: , ,
Abstract: A new Maximum Power Point Tracking ( MPPT) system has been proposed for PV-DC motor pump system by designing two PI controllers. The first one is used to reach MPPT by monitoring the voltage and current of the PV array and adjusting the duty cycle of the DC/ DC converter. The second PI controller is designed for speed control of DC series motor by setting the voltage fed to the DC series motor through another DC/DC converter. The proposed design problem of MPPT and speed controller is formulated as an optimization problem which is solved by Artificial Bee Colony (ABC) to search for optimal parameters of PI controllers. Simulation results have shown the validity of the proposed technique in delivering MPPT to DC series motor pump system under atmospheric conditions and tracking the reference speed of DC series motor. Moreover, the performance of the proposed ABC algorithm is compared with Genetic Algorithm (GA) for different disturbances to prove its robustness.
