Energy management and control method for a three port non-isolated DC-DC converter for PV applications

Résumé

This paper introduces a novel control law and energy management algorithm tailored for a boost-derived three port converter (TPC) employed in a standalone PV system. This converter can be used to interconnect a PV array, a battery and a resistive load through its three ports. Thanks to the devised energy management strategy, the converter exhibits three distinct operating modes, enabling it to efficiently utilize PVgenerated power and battery storage based on real-time demand. Additionally, the control scheme ensures maximum power point tracking (MPPT) at the PV side and maintains the output voltage at the desired level for the load. Furthermore, proactive monitoring of the battery's state of charge (SOC) safeguards against overcharging by automatically transitioning the converter to operate as a simple boost converter when necessary. Simulation results validate the effectiveness and robustness of the proposed energy management and control methodology, emphasizing its potential for enhancing the performance and reliability of standalone PV systems.
