“…The result was that PV/DG/BESS is more economical than WT/DG/BESS, to minimize the LCOE of an autonomous system, the Power Pinch Analysis (PPA) is applied in [6]. Two loops of optimization are implemented with, Economic Model Predictive Control, and Genetic Algorithm Optimization (GAO) to find out the optimum numbers of components [7]. Different loads are implemented on PV/BESS by using GAO to find out the optimal sizing of the system [8].…”

Ensuring low-cost and highly reliable electricity generation while meeting the demand load poses a significant challenge. Power plants operate continuously to produce power, with the Programmable Logic Controller (PLC) control system playing a crucial role in managing all the equipment. Power deficiencies in the PLC rooms can lead to equipment disturbances and potential damage to the plant. To address this problem and utilize the abundant solar energy in Libya, this study introduces the optimal sizing of an autonomous hybrid storage system using an optimization method. The Net Present Costs (NPC), Loss Power Supply Probability (LPSP), and Levelized Cost of Energy (LCOE) are employed to extract a suitable function database. The proposed system generates 7 kW of power to meet demand and is implemented in MATLAB. The Grey Wolf Optimization (GWO) method is applied to determine the optimal number of PV panels and BESS capacity for the autonomous hybrid system. The optimal solution obtained through GWO is determined to be 40 PV panels and a 60Ah BESS capacity.

ChronicObstructive Pulmonary Disease (COPD) is a primary cause of death in global, particularly in lowresource settings with insufficient medical facilities arising because of high costs of medical apparatus, diagnosis and treatment. The Long Term Oxygen Therapy (LTOT) is used to treat COPD patients as it has been shown to improve patient survival and better life expectancy; however, it is also an expensive treatment, making it difficult to use in poor-resource settings. This review discusses various LTOT devices and evaluates their suitable applicability in resource poor settings. The devices are compared based on their cost (both capital and operational) and performance. The article also discusses the observation of oxygen supply during treatment and the use of delivery systems.

“…HOMER (Hybrid Optimization for Multiple Energy Resources) is a piece of software invented by the National Renewable Energy Laboratory (NREL) for the simulation, optimisation, and sensitivity analysis of renewable energy systems [34]. HOMER software is designed to provide an optimised system configuration by evaluating the available technology options based on their energy resource potential in the target location [35]. The HOMER methodology employed in this case study is presented in Figure 4 [36].…”

This paper takes a cursory look at the problem of inadequate power supply in the rural healthcare centres of a developing country, specifically Nigeria, and proffers strategies to address this issue through the design of hybrid renewable energy systems combined with the existing unreliable grid in order to meet the healthcare load demand, thus ensuring higher reliability of available energy sources. The simulations, analysis and results presented in this paper are based on meteorological data and the load profiles of six selected locations in Nigeria, using which hybrid grid-connected systems integrating diesel, solar and wind energy sources are designed with configurations to give optimum output. The optimised design configurations in the considered case study, Ejioku, Okuru-Ama, Damare-Polo, Agbalaenyi, Kadassaka and Doso, produce very low energy costs of of 0.0791 $/kWh, 0.115 $/kWh, 0.0874 $/kWh, 0.0754 $/kWh, 0.0667 $/kWh and 0.0588 $/kWh, respectively, leveraging solar and wind energy sources which make higher percentage contributions at all sites. The load-following-dispatch strategy is adopted at all sites, ensuring that at every point in time, there is sufficient power to meet the needs of the healthcare centres. Further works on this topic could consider other strategies to optimise general energy usage on the demand side.
