Development of Controller Hardware-in-the-Loop Platform-based Battery Management System for Hybrid PV/Battery System

This paper presents a battery management system (BMS) for a hybrid power system that integrates the lithium-ion battery and the stand-alone photovoltaics (PV) with the purpose of ensuring system safety, meeting the load power demand, and stabilizing the DC bus voltage. In order to implement the proposed system, a hardware-in-the-loop (HIL) platform of Typhoon HIL404 device is employed for designing the hybrid system and testing the BMS control algorithm by using a TMS320F28069 microcontroller. Finally, real-time simulations using Typhoon-HIL software are conducted to validate the system performance and effectiveness of the proposed control strategy. The obtained results illustrate that the proposed hybrid system and control strategy achieve the system effectiveness, energy balancing of the battery system, and the stable DC bus voltage under different working conditions.
