Développement d’un système à base d’électrolyseur et pile à combustible pour l’amélioration de l’offre de l’énergie électrique et fluides en milieu hospitalier.

Abstract

The aim of this work is to develop a hybrid micro-energy system for improving the quality of electrical and fluid energy (case applicable to the supply of a hospital in Cameroon). Equipment malfunctions or failures in a hospital environment are usually caused by instability of the power supply. Also, oxygen deficiency or instability for resuscitation units does not allow health care personnel to work better. This finding was reinforced by the COVID 19 pandemic, which spread the absolute deficit of devices and resources for managing patients in respiratory distress. After a definition of hybrid micro-grid systems according to the literature review and the development carried out in the first two chapters, the architecture chosen is a hybrid micro-grid PV- PAC-Stand-alone electrolyzer that can be connected or not to the existing power grid. After presenting the development methods of the system, we opted for a technological modelling associated with the different mathematical equations followed by a representation in MATLAB/SIMULINK; and on the other hand, an economic modelling which consisted in individually sizing its various elements.
