Integration of MPPT Controller and Battery Energy Storage System for Enhanced Performance of a PV System in PMDC Motor

The increased demand for renewable energy sources has generated significant interest in the integration of photovoltaic (PV) systems with energy storage solutions. This research article conducts a comprehensive examination of the incorporation of Maximum Power Point Tracking (MPPT) controllers into a PV system to optimize energy supply for a Permanent Magnet DC (PMDC) motor under diverse operating conditions. To address the non-linearity of the PV system and fluctuations in the DC connection caused by environmental conditions, a Battery Energy Storage System (BESS) is commonly employed in this design. Various MPPT strategies, including Perturb and Observe (PO) and Incremental Conductance (INC) are compared to achieve maximum power under varying irradiance. An analysis of a double loop PI controller is also conducted. Bidirectional DC-DC converters, operating in both buck and boost modes during battery charging and discharging, are employed to ensure a consistent and uninterrupted power supply across the DC connection, thereby regulating the PMDC motor continuously. The mathematical modeling of each configuration is analyzed and implemented using MATLAB/Simulink.
