Lead-Acid Charge Controller For Stand Alone PV System

Abstract

In this paper, in an autonomous PV system, battery charging control is performed using DC to DC Buck converter. The battery charging procedure is managed by the DC to DC Buck Converter. In order to guarantee that the battery is charged steadily and effectively, MPPT techniques are employed. lead-acid battery is employed as the energy storage unit due to its cost-effectiveness. To make sure the system operates effectively, it must function at the maximum power point (MPP). Therefore, battery charging control is designed to track the MPP and maintain optimal performance of the PV system. Incremental Conductance (IC) methods. The proposed of this methods are applied to an autonomous PV system modeled in the MATLAB-Simulink program using identical sampling times at different step sizes. MATLAB-Simulink, a popular program in electrical engineering and system modeling, is used to model the system in order to confirm that it operates accurately and effectively. In this simulation, several step sizes are compared using the same sampling times. The compared of simulation results based on control performance criteria represented by settling time and steady state error. One of the most effective methods for monitoring the Maximum Power Point (MPP) in standalone PV systems is the Incremental Conductance (IC) approach. The PV system's performance can be maximized through system simulation, guaranteeing exact control over battery charging. The PV system's battery life and energy efficiency can be increased by achieving system stability and precisely tracking the MPP.
