Design of a Renewable hybrid photovoltaic-Electrolyze-PEM/Fuel Cell System using Hydrogen Gas

Abstract

Home Automation (or Smart Home) is a residential platform that connects different network devices to meet needs using Internet, computer, communication and control technologies. Equipped with different sensors; home automation devices have become a potential area that attracts worldwide attention and interest in the development of Internet objects. It plays an important role in adding semiconductors to sensor data to better understand environments around it. Researchers are trying to build semantic models to meet their own needs, resulting in limited reuse opportunities between various platforms and home applications. To do this, paper aims to provide a new ontology that follows publicly recognized standards for semantizing sensor data in home automation, including modeling sensors, context and semantic activity. In this vein, we proposed a precise simulation model combining solar energy with an energy recovery (fuel cell). A long-term energy storage component includes a water electrolyzer that is considered as a primary storage component and an Ultra-Capacitor storage component used as a short-term energy storage component. A precise scheme approach for energy management unit is developed and discussed according to excess and deficit modes in order to achieve the correct system operation. The design being proposed is simulated using Matlab / Simulink environment to demonstrate the reliability and effectiveness of the control strategy being applied. Indeed, the proposed strategy aims to control system operation by referring to an experimental data profile extracted in a typical weekly working period mode from the Tunisian meteorological database with expected conditions
