This paper presents an implementation of real-time energy management systems (EMS) to maximize the efficiency of the electricity distribution in an isolated hybrid microgrid system (HMGS) containing photovoltaic modules, wind turbine, battery energy storage system, and diesel generator (DG) which is used as a backup source. These systems are making progress worldwide thanks to their respect for the environment. However, hybridization of several sources requires power flow control (PFC). For this reason, in this work, a proper energy management system is developed using LabVIEW software and embedded in a suitable platform for the real- time management of the hybrid energy system. The developed EMS is tested and validated through a small-scale application which accurately represents the case study of an isolated mosque located in a remote area of Morocco. The aim of this paper is to (i) propose a novel modelling method and real-time monitoring interface under the LabVIEW software based on the real data obtained by an optimal sizing previously made using Homer-pro software and (ii) implement the power control system on a low-consumption embedded platform that is the Raspberry-pi3. 1. Introduction Access to energy is now considered as a central issue in the fight against poverty and economic development. The pro- portion of the world’s population with access to electricity has gradually increased in recent years. However, despite these improvements, 1.1 billion people are still deprived of this essential service, with the majority of these people located in Africa. Among those who have gained access to electricity in the world since 2010, only 20% live in rural areas [1]. In Morocco, almost 1.3 million rural people are deprived of electricity; i.e., 88902 households do not have access to electricity [2]. Most of these rural homes are located in isolated or hard-to-access locations and do not allow connection to an electrical grid since the investment cost is very large and online losses become significant. It is then necessary to be able to install the infrastructures for electrification in sparsely populated areas and away from the main grid. In recent years, rural electrification has been achieved with DG or with stand-alone renewable energy sources, including photovoltaics and wind power, which have been considered promising to meet the growing demand for energy and play a very important role in the clean energy production. However, renewable energy depends to a large extent on wind speed or solar radiation. In order to provide a continuous supply by taking advantage of the complemen- tary nature of the two sources of energy, one solution is to hybridize the types of sources in the form of the microgrid. HMS were considered attractive and preferred alterna- tives; indeed, the development of microgrid in rural areas makes it possible to electrify villages located far from the dis- tribution grid with renewable energy sources (RES) in a more sustainable way. Another major factor in the development of microgrid systems is the sharp drop in the cost of renewable energies, which makes these energies competitive with traditional fossil fuels. Similarly, energy storage solutions are currently undergoing significant development due to Hindawi International Journal of Photoenergy Volume 2019, Article ID 8974370, 16 pages https://doi.org/10.1155/2019/8974370
