Techno-Economic and Environmental Analysis of Stand-Alone Hybrid Energy Systems in Remote Areas: Case Study of the African Unity Road's Petrol Station and Tecom Towers in Southern Algeria
Main Article Content
Abstract
This study assesses the techno-economic and environmental performance of a standalone PV/DG/BESS system for powering gas stations and telecom towers in the Arak, Mouly Lahcen, and Qaim Inguzzem regions—specifically, the African Unity Road. HOMER software is performed a comparative techno-economic and environmental performance analysis based on the net present cost (NPC), cost of energy (COE), loss of power supply probability (LPSP), energy autonomy (EA), excess energy (EE), renewable fraction (RF), and greenhouse gas emissions (CO2). The simulation results show that that the PV/DG/BESS system installed in Arak has the lowest NPC of $6124087 and COE of $0.395/kWh, with the LPSP of 67.88%, EA of 44.68%, EE of 526,134 kWh/year, RF of 44.7%, and the CO2 of 360.260 tons/yr. Conversely, the PV/DG/BESS system implanted in Mouly Lahcen is ranked the first techno-environmental system with the LPSP of 71.82%, EA of 45.12%, %, EE of 560,764 kWh/year, RF of 45.12%, and the CO2 of 357.376 tons/yr. This system is ranked second economically, with the NPC of $6139977 and COE of $0.396/kWh. Finally, the PV/DG/BESS system deployed in Inguzzem is the worst system among all system, with the NPC of $6646385, COE of $0.429/kWh, LPSP of 28.88%, EA of 31.14%, EE of 182,918 kWh/year, RF of 31.2%, and CO2 emissions of 447.811 tons/yr.
