Dynamic Simulation and Validation ofHybrid Energy Systems: A Case StudyApproach Using MATLAB/Simulink

Abstract

This thesis investigates the dynamic simulation of hybrid thermal energy systems that integrate both conventional and renewable sources. A representative industrial facility is used as a case study to demonstrate the modeling, calibration, and validation of such systems under seasonally varying operating conditions. The model is implemented in MATLAB/Simulink using the CARNOT Toolbox, incorporating key components such as heat pumps, pellet boilers, buffer storage tanks, and photovoltaic (PV) generation. The objective is to develop a physically meaningful and practically applicable simulation model that accurately reflects the system’s energy behavior. Real operational data are used for model validation, with results showing close agreement between simulated and measured energy use across heating and cooling periods. Seasonal test cases highlight the effectiveness of the system's automated control strategies and the interaction between thermal storage, HVAC loads, and renewable input. The validated model serves as a tool for further analysis and optimization, offering a scalable approach to assess similar hybrid energy systems in industrial settings. This contributes to the broader goal of enhancing energy efficiency and decarbonization in the context of integrated thermal-electric building systems.
