Decentralized and Communicating Management of a Hydrogen-Based Microgrid

L. Elmahni, L. Bouhouch and A. Ihlal

This document presents a hierarchical energy management strategy for a hydrogen/battery based micro grid (MG). The structure of this MG includes a photovoltaic (PV) generator, a battery storage system (BESS) and a hydrogen subsystem consisting of a proton exchange membrane fuel cell (PEMFC), an electrolyser (ELZ) and a hydrogen tank (H2TANK). The operating strategy adopted in this micro grid is based on maximizing the PV utilization rate, minimizing the annual overall cost and improving reliability according to the Loss of Power Supply Probability (LPSP) concept and the economic model developed using the Life Cycle Cost (LCC) concept.) The hierarchical control based on the Raspberry Nano computer is divided into two layers: the lower layer, also called the physical layer (Hardware), which is composed of various micro sources and DC-DC converters and the upper layer, which is the global control layer and is based on local Wi-Fi communication, using a module, for example Node MCU type ESP8266.
