New Structure of Solar Battery Optimizer in Maximum Power Mode

This paper proposes a six-step optimizer for maximum power point tracking (MPPT) in photovoltaic (PV) systems, designed to enhance energy efficiency under varying operating conditions. It presents a detailed block diagram of the algorithm and a simulation model developed in the OrCAD PSpice environment. The study introduces an original equivalent circuit model of a solar battery, enabling accurate approximation of its static current-voltage (I-V) characteristics. Stability requirements for the optimization loop are defined, and a hardware implementation of the optimizer is proposed. The simulation results validate the effectiveness and precision of the optimizer, demonstrating its adaptability and potential for integration into modern microprocessor systems for real-world applications.
