Rwanda is an East African Community (EAC) nation with rapid and remarkable past development in different sectors and still with the ambitious targets and plans to be achieved in the coming years ahead. The government plans universal electricity access by 2024 with 52% grid connection and 48% off-grid connections. In the transport sector, the concept of electric vehicles has been initiated and started in order to contribute to the UN Paris agreement and decrease the reliance of the transport sector on gaseous fuels which are one source of air pollutants leading to climate change, premature deaths, and morbidity associated with poor air quality. With higher electricity demand than the generation of the Rwandan power grid, different energy strategies are being developed with the overall objective to achieve the targeted universal energy access. In order to overcome the aforementioned issue, this paper proposes an integration of solar PV microgrids for the satisfaction of electric vehicle (EV) technology in Rwanda. Using HOMER Grid software, a managed EV charging station is simulated to a grid connected solar PV microgrid with storage in order to assess the economic impact. The results show that the proposed technology can lower the levelized cost (LCOE) of electricity by 139.7%. This study can contribute to further research developments in either different perspectives related to the integration of distributed energy resources (DERs) with electric vehicles or studies related to affordable and environment-energy systems.

微电网和电动汽车技术在国家电网中的整合是卢旺达可持续发展的关键推动因素

卢旺达是一个东非共同体（EAC）国家，过去在不同领域取得了快速而显着的发展，并且在未来几年仍具有雄心勃勃的目标和计划。政府计划到 2024 年普及电力接入，52% 的电网连接和 48% 的离网连接。在运输部门，电动汽车的概念已经启动并启动，以促进联合国巴黎协定并减少运输部门对气体燃料的依赖，气体燃料是导致气候变化、过早死亡、以及与空气质量差相关的发病率。由于电力需求高于卢旺达电网的发电量，因此正在制定不同的能源战略，其总体目标是实现有针对性的普遍能源接入。为了克服上述问题，本文提出了太阳能光伏微电网的集成，以满足卢旺达电动汽车 (EV) 技术的需求。使用 HOMER Grid 软件，将托管电动汽车充电站模拟到具有存储的并网太阳能光伏微电网，以评估经济影响。结果表明，所提出的技术可以将电力的平准化成本 (LCOE) 降低 139.7%。这项研究可以促进与分布式能源 (DER) 与电动汽车集成相关的不同视角的进一步研究发展，或者与可负担得起的环境能源系统相关的研究。使用 HOMER Grid 软件，将托管电动汽车充电站模拟到具有存储的并网太阳能光伏微电网，以评估经济影响。结果表明，所提出的技术可以将电力的平准化成本 (LCOE) 降低 139.7%。这项研究可以促进与分布式能源 (DER) 与电动汽车集成相关的不同视角的进一步研究发展，或者与可负担得起的环境能源系统相关的研究。使用 HOMER Grid 软件，将托管电动汽车充电站模拟到具有存储的并网太阳能光伏微电网，以评估经济影响。结果表明，所提出的技术可以将电力的平准化成本 (LCOE) 降低 139.7%。这项研究可以促进与分布式能源 (DER) 与电动汽车集成相关的不同视角的进一步研究发展，或者与可负担得起的环境能源系统相关的研究。
