本文介绍的结果涵盖了电器的效率,以支持减少电力需求的小型电网和可拆卸的太阳能家庭系统。此外,该研究还比较了不同规模的DC与AC小型电网的功效。在一般情况下,结果表明,直流微型电网可以在一个较小的地理足迹,提供有效的电器集成在系统实施的网站竞争。在更高的电气化“层次”,我们还介绍了肯尼亚和乌干达的五个e4D太阳能光伏(PV)微型电网项目的成果和经验。这项工作包括分析社区参与,电力负荷特性,和系统运行的小型电网在农村设置。结果表明,能源消耗的显着不同的网站之间,与社会经济因素,而所有那些村庄的交易中心经历了不同程度的业务增长。这项研究的总体结果清楚地表明,微型电网干预措施不仅通过加强教育和卫生服务来振兴农村社区,而且还与现有企业的增长和新企业的创建有关。因此,建议在必要时修订农村电气化政策,优先促进和吸引对分散的小型电网的投资。
This paper presents results covering the efficiency of appliances to support reduce power needs in both mini grids and upgradeable solar home systems. In addition the research has compared the efficacy of DC vs AC mini grids at different scales. In general, the results indicated that DC mini grids could compete well at sites with a smaller geographical footprint, providing efficient appliances are integrated at system implementation. At the higher'tiers' of electrification, we also present results and experiences from the five e4D solar photovoltaics (PV) mini-grid projects in Kenya and Uganda. The work includes analysis of community engagement, electrical load characterisation, and system operation of the mini grids in rural settings. The results indicate that energy consumption varies significantly between the sites, associated with socio-economic factors, whilst all the villages' trading centres have experienced varying levels of business growth. Overall outcomes from this research provide clear indications that mini-grid interventions not only invigorate rural communities by enhancing education and health provisions, but are also associated with growth in existing businesses and the creation of new businesses. Therefore, it is recommended that where needed, rural electrification policies be amended to give priority to facilitate and attract investment in decentralized mini grids.
