意义 这项研究提供了撒哈拉以南非洲 (SSA) 社区电压质量的详细地图，并将电力系统数据与家庭调查和访谈联系起来，以全面了解不可靠电网下的生活。 SSA“人人享有现代能源”背景下的可靠性传统上关注的是停电而不是电压质量，关注的是企业而不是家庭。我们的研究通过提供坦桑尼亚安古贾的能源获取说明性案例研究，扩展了 SSA 的能源获取学术和可靠性问题。随着电力供应在财政拮据的社区中不断扩大，形成了容量有限的连接，我们的安古贾研究为 SSA 社区提供了至关重要的视角，以了解电力供应意味着什么。 “人人享有现代能源”是一项国际支持的旨在为人们提供电力服务的倡议，预计将有助于减少贫困引起的脆弱性。它已成为实现可持续发展目标的主要战略，特别是在撒哈拉以南非洲地区。然而，当电力由容量有限的电网向资源有限的人口供电时，服务质量可能会在空间和时间上发生变化。本研究以坦桑尼亚安古贾的案例研究为基础，探讨了电力服务的质量。通过 1) 开放式访谈、2) 详细的电力系统监测和 3) 家庭调查，我们展示了电压质量如何显着变化，即使在高度本地化的环境中也是如此。波动最好的情况是导致灯光昏暗，最坏的情况是停电和电器损坏，从而使许多安古贾居民无法享受到现代能源带来的预期好处。通过将对物理系统的广泛了解与访谈和调查相结合，这项工作提出了一个在经济和物理上受到限制的系统中电压质量的独特映射，并强调了低质量服务对贫困用户造成的后果。
Significance This research provides a detailed mapping of voltage quality in a sub-Saharan African (SSA) community and connects power systems data to household surveys and interviews for a comprehensive understanding of life under an unreliable grid. Reliability within the context of “modern energy for all” in SSA has traditionally focused on power outages rather than voltage quality and on businesses rather than households. Our research expands on energy access scholarship and reliability concerns in SSA by offering an illustrative case study of access in Unguja, Tanzania. As electricity access expands in financially constrained communities, creating capacity-constrained connections, our Unguja study offers a crucial look at what that access means for SSA communities. “Modern energy for all,” an internationally supported initiative to connect populations to electricity services, is expected to help reduce poverty-induced vulnerabilities. It has become a primary strategy for meeting sustainable development goals, especially in sub-Saharan Africa. However, when electricity is supplied by a capacity-constrained grid to a resource-constrained population, the service quality can vary both spatially and temporally. This research explores the quality of electricity services based on a case study of Unguja, Tanzania. Using 1) open-ended interviews, 2) detailed electricity-systems monitoring, and 3) household surveys, we show how voltage quality varies significantly, even within highly localized settings. Fluctuations result in dim lights at best and power outages and broken appliances at worst, denying many Unguja residents the expected benefits of access to modern energy. By combining an extensive understanding of the physical system together with interviews and surveys, this work presents a unique mapping of voltage quality in a system that is financially and physically constrained and highlights the consequences of poor-quality service for poor users.
