Intelligent Energy Management Dedicated to Vehicle-To-Home Applications: A Realistic Autonomous Hybrid Power System Using a PEMFC

Vehicle-to-Home (V2H) has been identified as an interesting area of research because of its public services, which have incorporated new technologies and new devices for a better quality of life. The main goal of developing a smart home is to produce more efficient energy and achieve an optimal economy. To do this, hybrid electric autonomous systems which provide a required load demand are considered as an option to achieve effective energy production without interruption. In this context, a specific V2H simulation system integrating PEMFC technology (energy exchange membrane fuel cells), solar power and a Supercapacitor is described and developed. To balance between energy demand and supply, a unidirectional energy flow transfer is performed between the PEMFC hybrid electric vehicle and the home by providing the appropriate H2 amount. Indeed, the electric vehicle intervenes occasionally through its fuel reserve to boost the energy recovery process when the PEMFC and Supercapacitor operation come across a problem. Therefore, an intelligent energy management approach (IEM) devoted for the V2H system is studied and evaluated. The proposed IEM serves for limiting energy consumption through the smart control of household electrical systems exploitation and equipment state in order to sustain the requirements. The obtained results are discussed and tested using the MATLAB / Simulink software. Indeed, given the Tunisian meteorological database and home consumption reports (on/off appliances) extracted for 4 consecutive days, the proposed V2H technology provides an energy recovery rate of 17% and improves the system efficiency to 31%.
