“…The latter is sized to provide sufficient power to support the main electric demand of the system. Small lithium-ion batteries have been placed inside the homeboxes, to provide energy during short-term power outages and faults in the microgrid [12].…”

“…6a. Each connection between the hub and the homebox requires two wires rated at +60 V and -60 V with respect to ground at the hub [12]. Regrouping these two wires in one single-core cable is the first approach in reducing the cost and improving the reliability of the connections.…”

“…Regrouping these two wires in one single-core cable is the first approach in reducing the cost and improving the reliability of the connections. The cross-section of each wire is 1.5 mm 2 to support the 2A maximum current to each home [12], as all the homeboxes have the same installed power. Steel Wire Armour PVC is used to protect the cables from the impact of weather and increase the durability of the system in an underground design configuration.…”

“…Therefore, we propose in this paper a form of radial configuration called the star radial configuration. This is a hub-to-homebox [12] cabling design, that has the advantage of directly connecting active customers to the main source "hub" through the "homeboxes", as shown in Fig. 1.…”

The construction of low-cost nanogrids could help speed up the electrification rate in remote communities in sub-Saharan Africa. One of the challenges in nanogrid design for these communities is the uncertainty in future load demand profiles impacting the cabling topology. We propose two new wiring design approaches for radial direct current power distribution systems. The first one is a modified minimum spanning tree (MST) algorithm and the second one is an adaptive shuffled frog leaping algorithm (SFLA). Their objective is to identify the optimal cable path and the lowest cost wiring characteristics to electrify rural areas with poor infrastructural development. A comparative study of computation burdens has shown the applicability limits relative to the SFLA based approach and encouraged the implementation of the MST as it is faster and does not imply any limitation regarding the number of dwellings to electrify, while providing low-cost wiring design option. The latter is applied to a village located in Kenya and demonstrated more than 25% savings on the entire system cabling cost compared to a classical wiring design based on shortest-path calculation.

“…Most LMICs have uneven population distributions that centralise in urbanised areas (Rodríguez-Pose & Hardy, 2015). To build a cost-effective energy infrastructure accounting for these demographic distributions, Ministries of Energy commonly build central electrical grids that cover high-density areas, prompting remote health facilities and public services to build their own self-sufficient mini-grids, using more diverse sources of energy (Neal et al, 2020;Remson, 2015). Rural PHC electrification efforts can leverage and expand on these disconnected grids to power surrounding residential areas and public services -gaining grounds towards the SDG target 7.1.…”

Critical disparities threaten health care in developing countries and hinder progress towards global development commitments. Almost a billion people and thousands of public services are not yet connected to electricity -a majority in sub-Saharan Africa. In economically fragile settings, clinics and health services struggle to gain and maintain their access to the most basic energy infrastructure. Less than 30% of health facilities in LMICs report access to reliable energy sources, truncating health outcomes and endangering patients in critical conditions. While 'universal health coverage' and 'sustainable energy for all' are two distinct SDGs with their respective targets, this review challenges their disconnect and inspects their interdependence in LMICs. To evaluate the impact of electrification on healthcare facilities in LMICs, this systematic review analysed relevant publications up to March 2021, using MEDLINE, Embase, Scopus, CENTRAL, clinicaltrials.gov and CINAHL. Outcomes captured were in accordance with the WHO HHFA modules. A total of 5083 studies were identified, 12 fulfilled the inclusion criteria of this review -most were from Africa, with the exception of two studies from India and one from Fiji. Electrification was associated with improvements in the quality of antenatal care services, vaccination rates, emergency capabilities and primary health services; with many facilities reporting high-quality, reliable and continuous oxygen supplies, refrigeration and enhanced medical supply chains. Renewable energy sources were considered in six of the included studies, most highlighting their suitability for rural health facilities. Notably, solar-powered oxygen delivery systems reduced childhood mortality and length of hospital stay. Unavailable and unreliable electricity is a bottleneck to health service delivery in LMICs. Electrification was associated with increased service availability, readiness and quality of care -especially for women, children and those under critical care. This study indicates that stable and clean electrification allows new heights in achieving SDG 3 and SDG7 in LMICs.
