“…It can be used for some types of renewable energy sources, such as PV, wind turbines, and micro-hydro combined with diesel generators (DG) both on DC and AC connections. Several studies applied this type of inverter in the configuration of microgrids in remote areas due to its reliability (Mudaheranwa et al, 2023;See et al, 2022;Upadhyay & Sharma, 2016;Yaouba et al, 2022). The specific type used in this study was the Leonics Apollo MTP-413F with a capacity of 25 kW which was selected based on the DC to AC power capacity ratio (Díaz-Bello et al, 2023).…”

Microgrid systems are part of the most reliable energy supply technologies for rural communities that do not have access to electricity but the system is generally dominated by diesel generators (DG). The implementation of de-dieselization programs to ensure efficient diesel operations requires addressing several scenarios such as the replacement of diesel completely with 100% renewable energy sources at a significant cost. The design and selection of appropriate configuration, as well as operating patterns, need to be considered in adopting economical and reliable microgrid systems. Therefore, this study aimed to design an optimal configuration and operational pattern for microgrid systems for the frontier, outermost, and least developed (3T) regions using Baron Techno Park (BTP) in Indonesia as a case study. The optimization was conducted through HOMER software combined with benefit-cost analysis and the focus was on daily load variations, selection of control algorithms, reconfiguration of the power supply system, and setting of the diesel generator operating hours. The results showed that the optimum configuration was achieved using loads of resort, 24 kWp of PV, 288 kWh of BESS, load-following (LF) as dispatch controller, and 25 kVa of DG. Moreover, the proposed microgrid system produced 12% excess energy, 36% renewable fraction (RF), 13.25 tons reduction in CO2 emissions per year, $0.28 LCOE per kWh, $250,478 NPC, and a benefit-cost ratio (BCR) of 0.89. It also had a potential energy efficiency savings of 55.56% and a cost efficiency of 20.95% compared to existing system configurations. In conclusion, the study showed that the addition of DG to microgrid systems in 3T areas was more optimal than using only PV and batteries. An effective operating schedule for the DG was also necessary to improve RF and reduce expenses. Furthermore, other energy storage devices considered less expensive than batteries could be introduced to improve the economics of microgrid systems in the 3T region.

“…The most prevalent theme, that of "hybrid energy", focuses largely on the feasibility and performance of systems that combine renewable energy, fossil fuel-based energy, and/or storage (Nigussie et al, 2017;Rehman et al, 2020;Thirunavukkarasu and Sawle, 2021). The theme on "minigrid", for example, discusses the role of microgrids and minigrids in providing electricity in remote, low-density areas in an adjustable and expandable manner (Moner-Girona et al, 2018;Adefarati and Bansal, 2019;Mudaheranwa et al, 2023). With a more specific focus on system design, the theme on "system optimization" explores the balance among parameters such as the net present cost, the cost of electricity, the share of renewable energy, and the reliability of supply within a (hybrid) microgrid or minigrid system, and the role of an energy management strategy therein (Das et al, 2021;Mustafa Kamal et al, 2022;Sharma et al, 2023).…”

IntroductionThe target of universal access to affordable, reliable, and modern energy services—key for individual, social, and economic well-being—is unlikely to be achieved by 2030 based on the current trend. Public policy will likely need to play a key role in accelerating progress in this regard. Although perspectives from the field of policy studies can support this effort, to what extent they have been employed in the literature on energy access remains unclear.MethodsThis study analyzed nearly 7,500 publications on energy access through a combination of bibliometric review and computational text analysis of their titles and abstracts to examine whether and how they have engaged with public policy perspectives, specifically, policy process research, policy design studies, and the literature on policy evaluation.ResultsWe discovered 27 themes in the literature on energy access, but public policy was not among them. Subsequently, we identified 23 themes in a new analysis of the 1,751 publications in our original dataset, mentioning “policy” in their title or abstract. However, few of them engaged with public policy, and even those that did comprised a rather small share of the literature. Finally, we extracted phrases pertaining to public policy in this reduced dataset, but found limited mention of terms related to the policy process, policy design, or policy evaluation.DiscussionWhile to some extent this might reflect the multidisciplinary nature of the research on energy access, a manual review of the abstracts of select publications corroborated this finding. Also, it shed light on how the literature has engaged with public policy and helped identify opportunities for broadening and deepening policy relevant research on energy access. We conclude that, despite their relevance to energy access, public policy perspectives have infrequently and unevenly informed existing research on the topic, and call on scholars in both communities to address this gap in the future.
