“…Le coût net actuel total ( TNPC), le coût total annualisé ( CTA) et le coût localisé de l'énergie ( LCOE ) sont les méthodes d'évaluation économique les plus courantes. TNPC est la somme du coût net actuel ( CNP ) de composants [25]. A l'aide du logiciel d'analyse technico-économique Homer®, il est possible de choisir la configuration la plus appropriée du système énergétique hybride qui est basé sur les différents coûts.…”

L'étude de faisabilité et la conception optimale d'un système énergétique hybride pour fournir de l'énergie électrique à un site éloigné de M'Sila est examinée dans ce papier. Le but de ce document est de concevoir et de simuler un mini-réseau hybride PV/batterie optimal qui fonctionne d'une manière fiable, afin d'assurer une alimentation électrique ininterrompue. En raison de la nature intermittente des ressources renouvelables, un générateur diesel y est ajouté. Afin de réaliser l'étude de faisabilité du système hybride, la conception optimale du système est basée sur un modèle de simulation développé par le logiciel Homer®. Le logiciel est utilisé pour l'évaluation technique, économique et environnementale. Le concept de la probabilité de perte d’énergie (LPSP) est supposé nul (DPSP = 0 % signifie que la charge est toujours satisfaite), avec un coût net actuel total (TNPC) et un coût énergétique (LCOE) minimal. Dans ce contexte, un profil de charge pratique du site est utilisé avec des données météorologiques réelles. Les résultats de l'optimisation catégorisée montrent que, dans le cas d’une consommation de 9.8 kWh/jour, le système hybride PV/DG/Batterie peut être considéré économique dans le cas où le prix du diesel ne fluctue pas. Le système optimal est composé d'un module PV de 3 kW, d'un générateur diesel de 1 kW, d'un convertisseur de 2 kW et de 4 batteries modèle Hoppecke. D'après les résultats obtenues, la configuration est économique avec un coût en capital de 5.656 $, un coût d'exploitation annuel de 431 $/an, un coût net actuel de 11.159 $/an et un coût unitaire d'énergie de 0.244 $/kWh avec une fraction d'énergie renouvelable de 86 % et une réduction plus de 90.79% dans les émissions.

The There are many factors influencing the performance of photovoltaic (PV) systems. Among these factors, temperature and solar radiation are two major parameters that have a large effect on the efficiency of PV systems. The cell temperature of PV panels is related to the ambient temperature while the solar radiation incident on the surface of the PV modules depends on the slope and azimuth of these modules. Furthermore, ground reflectance (albedo) affects the irradiance incident on the PV panel surface, which in turn affects the output of a PV system. Nevertheless, the effects of these factors on the economic performance of the solar PV systems are scarcely reported. This paper presents a complete design of a stand-alone PV/battery system to supply electric power for a mobile base station in Choman, Erbil, Iraq. The effects of different factors on the total electricity produced by PV arrays and its economic performance are simultaneously investigated. HOMER software has been used as a tool for the techno-economic and environmental analysis. As indicated from the simulation results, the PV array capacity and its economic performance are highly affected by the variation of the slope and azimuth. With a base case (albedo of 20% and average annual ambient temperature of 11°C), the best feasible system which is achieved by facing PV due to south with a tilt angle of 40° or 45°, is found to have net present cost (NPC) of 70595 $ and cost of energy (COE) of 0.54 $/kWh. Moreover, the results indicate that increasing the ground reflectance from 10% to 90% results in a 7.2% decrease in the PV array capacity and about 3% decrease in the NPC and COE. On the other hand, increasing the ambient temperature from 0°C to 40°C results in a 19.7% increase in the PV array capacity and an 8.2% increase in the NPC and COE. Furthermore, according to the ambient temperature of Choman, using PV modules with high sensitivity to temperature is found to be an attractive option. Provided simulation performance analysis proves that the studied parameters must be treated well to establish an enabling environment for solar energy development in Iraq.

“…Their results show that PV/Diesel/Wind system is more profitable economically and diminishes greenhouse gas emissions for protection of environment. An optimum off-grid PV/Diesel hybrid energy system for rural electrification in Iraq has been conducted by Ali Saleh and Sara [13] with HOMER software in order to implement techno-economic and environmental feasibility. Analysis study was presented to estimate the standalone electrification for comparison with grid expansion.…”

The Comoros is an archipelago in the Indian Ocean located in the Mozambique Channel between the African continent and Madagascar. Geographically Comoros is composed of four islands: Grande Comores, Anjouan, Mohéli and Mayotte (under French administration). Apart from Mayotte, the others three independent islands commonly known as the Union of the Comoros are suffering from energy stress since their independence year 1975 until nowadays. The energy supplied and distributed by the national electricity company, SONELEC produced by diesel engines, is not stable with so much load shedding all the time. This instability energy leads to a lack of a phone network in some telecommunications towers connected to grid. The majority of telecommunications towers are located in rural areas not connected to grid and running on diesel generators, which once again leads to a problem with the telecommunications network when diesel engines fail. The two competing companies which operate in the field of telecommunications in the Comoros, namely Comores Télécom, a national public company and Telma, the private one, are still unable to ensure the provision of the telecommunications network on a regular basis. This is why we propose in the present work, a sizing of hybrid system composed essentially of a diesel generator, a wind turbine and a photovoltaic solar system with storage in batteries for supplying telecommunications towers in order to permanently ensure the provision of the telecommunications network for the well-being of the population. Our future energy must be based on non-polluting energies with significant resources. Renewable energies are the best candidates but with intermittent production especially in rural areas not connected to the national electricity grid whose energy demand is more important to meet the needs of the population.
