Abstract
This work is motivated by the current situation in the world in particular the spread of COVID-19. Building quarantine centers is one of the most important means used in combating the Corona epidemic, but connecting these centers to the electricity distribution network at the appropriate time is not always possible. This paper proposed a Hybrid off-grid Energy System (HES) to effectively energies the quarantine centers economically and environmentally. To achieve this aim, the load profile of the quarantine center is estimated, the system components are modeled and the system design is optimized. In addition, the developed approach was tested using a real case study considering realistic input data. HOMER-pro program is used to simulate and optimize the system design. The results revealed the potential of the HES to provide environment-friendly, cost-effective, and affordable electricity for the studied quarantine center, as compared to only diesel generators system. For the considered case study, it is found that the PV-Wind-Diesel hybrid power system is able to cover the connected load with the lowest cost in comparison to other possible HES structures. It also environmentally friendly as it has the least harmful emissions. Finally, it is proved that the developed approach gives a reasonable solution to the decision-makers to find a fast, economic and reliable solution to energies the quarantine centers.
Highlights
Friendly sources of energy become a necessity to replace traditional fossil fuel in various applications [1, 2]
Using HOMER, results suggested that the optimal configuration based on the lowest net present cost (NPC) cost of energy (COE) is PV-wind hybrid system with battery storage
Different Hybrid off-grid Energy System (HES) models consists of combined sources of energy such as wind, photovoltaic (PV), and diesel generator are proposed for a village in the north-eastern part of Saudi Arabia [11]
Summary
Friendly sources of energy become a necessity to replace traditional fossil fuel in various applications [1, 2]. Example of HES is an energy system that produces energy from solar system, storage battery and electrical generator[7]. Babatunde et al gave an analysis of an off-grid PV-wind-battery-gasoline generator-HES for a single residential apartment owned by a low-income earner in particular technical, economic and environmental considerations [7]. The results assured that HES is promising technology with high efficiency, environmentally friendly and affordable for low-income household, as compared to using only gasoline generators[7]. Different HES models consists of combined sources of energy such as wind, photovoltaic (PV), and diesel generator are proposed for a village in the north-eastern part of Saudi Arabia [11]. HES is cost effective compared to diesel fueled generators which makes them very attractive to low-income countries to adopt them [7].
