BAT Algorithm: A Novel Approach for MPPT Control Design of PV Generator Supplied SRM

Abstract

Maximum Power Point Tracking (MPPT) is used in Photovoltaic (PV) systems to maximize its output power, irrespective of the atmospheric conditions and electrical load characteristics. This paper suggests a new MPPT control design to PV system supplied Switched Reluctance Motor (SRM) based on PI controller. The developed PI controller 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 design task of MPPT is formulated as an optimization problem which is solved by BAT search algorithm to seek for optimal parameters of PI controller. Simulation results have shown the validity of the suggested technique in delivering MPPT to SRM under atmospheric conditions. Moreover, the performance of the developed BAT algorithm is compared with Particle Swarm Optimization (PSO) for different disturbances to confirm its robustness.
