This paper presents the integration of controller hardware with virtual laboratory settings for real-time simulation of battery energy storage systems (BESS). In this innovative approach, the inclusion of controller hardware facilitates real-time interaction with virtualized BESS models, enabling diverse testing scenarios and optimizing system performance. The paper highlights the significance of this integrated framework not only for testing BESS under varying conditions but also for its educational implications. The virtual laboratory emerges as a powerful tool for teaching and training, offering an immersive platform for students and professionals to engage in hands-on learning experiences. Through interactive simulations, users can design, test, and optimize controller strategies for BESS, fostering a dynamic educational environment. This work represents a pivotal advancement at the intersection of simulation technologies and practical applications, contributing significantly to BESS research, education, and industrial training. The proposed framework’s versatility and effectiveness mark a transformative step forward in the integration of hardware-enhanced simulations for comprehensive testing, teaching, and training in the realm of BESS.
