能源服务对人类福祉和发展至关重要，没有可靠的能源，就很难摆脱维持生计的生活方式和贫困。在这里，我们报告了在肯尼亚和乌干达进行的四种相同能力的农村微型格栅干预措施，它们具有不同的社会经济特征和人口统计特征。所介绍的研究成果简要讨论了干预措施的准备阶段，包括为管理迷你格栅项目的社区合作社的技术设计、部署阶段和建立提供信息的社区调查。这里的主要重点是吸取的教训，包括系统设计和各种负载条件下的微型格栅性能。结果表明，社区对电力的吸收明显且不断增加，强度随所用电价的不同而不同。在四个微型电网中，日电力增长率的差异被认为是8倍。乌干达的微型电网以接近公用电网电价的价格运行，并在两年内达到了28千瓦时/天的设计上限。相比之下，肯尼亚的微型电网收取了更高的成本回收关税，这限制了需求，系统的运行低于设计限制。这些发现不仅对系统设计有影响，而且对系统的稳定性和寿命也有影响。这里采取的办法是，由以社区为中心的合作社运营交付的微型格栅，目前已嵌入两国农村电气化主管部门/机构，并计划在2019/2020年开展更多类似项目。与其他方法相比，本文还讨论了这种微格子概念的应用、分支和复制。
Energy services are crucial to human wellbeing and development, and without reliable energy, it is difficult to escape subsistence lifestyles and poverty. Here, we report on four identical capacity rural minigrid interventions undertaken in Kenya and Uganda with differing socioeconomic characteristics and demographics. The research outcomes presented briefly discuss the preparation stages of the interventions including community surveys that informed the technical design, deployment phases, and setup of the community cooperatives to manage the minigrid projects. The main focus here is on lessons learned, including system design and minigrid performance under various load profiles. The results show a clear and increasing uptake of power by the communities with intensities varying depending on the electricity tariff used. Across the four minigrids, daily electricity growth rates are seen to vary by a factor of 8. The Ugandan minigrids operated at close to utility grid tariff and reached the 28-kWh/day design limit within two years. By contrast, the Kenyan minigrids charged a higher cost recovery tariff, which capped the demand and systems operate below the design limit. These findings have implications not only to system design but also to system stability and longevity. The approach taken here, of community centered cooperatives running the delivered minigrids, is now embedded within the rural electrification authorities/agencies in both countries, with additional similar projects being planned in 2019/2020. The application, ramifications, and replication of such a minigrid concept as compared to other approaches are also discussed in this paper.
