发展中国家的微电网为光伏发电（PV）作为一种能源赋能技术提供了重要的应用机会。作者预计，在未来十年内，这一应用将达到10吉瓦。分享最佳做法将促进这一部门的发展。作者是成功在微电网中安装1/3兆瓦的团队的一部分，并介绍了经验教训和确定关键指标的有用方法。光伏发电是印度农村电气化的一部分，是当前全球光伏微电网的代表。该项目为印度维萨卡帕特南的57个村庄提供基本的照明和电力。该项目的目标是优化功率和成本。提出了各种度量标准：成本、时间、操作和维护以及性能。还讨论了成本控制、利益相关者考虑、安装后支持和用户付款收集的实施策略。在项目执行、当地人民的参与和应对的挑战方面提出了学习要点。更详细地检查了需求能力水平（可用小时数）方面，并执行建模以确定在给定成本约束的情况下提高水平的最佳方法。将实际数据与建模相结合是光伏和微电网优化的有效方法。这一案例研究从数量上支持了使用光伏对农村电气化的价值。在印度，联邦政府计划增加2000多个站点，除此之外，在全球微电网电气化背景下，光伏发电也有很大的机会。版权所有©2013 John Wiley & Sons， Ltd
Micro‐grids in developing countries present a significant application opportunity for photovoltaics (PV) as an energy‐enabling technology. The authors project 10 GW for this application in the next decade. The growth of this sector will be enhanced by shared learning of the best practices. The authors are part of a team that successfully installed 1/3 MW in micro‐grids and presented the lessons learned and a useful methodology for determining key metrics. The PV is part of the rural electrification in India and is representative of current global PV micro‐grids. This project provides basic lighting and electricity for 57 villages in Visakhapatnam in India. The project was carried out with a goal of optimizing power against cost. Various metrics are presented: costs, time, operations and maintenance, and performance. Also discussed are implementation strategies for cost containment, stakeholder considerations, and post‐install support and user payment collection. Learning points are presented on project execution, engagement of local people, and challenges addressed. The aspect of demand capacity level (hours of availability) is examined in more detail, with modeling being performed to identify an optimal approach to increasing the level given the cost constraints. The combination of real data and modeling is a useful approach for PV and micro‐grid optimization. This case study quantitatively supports the value of the use of PV for rural electrification. Beyond this example in India, where the federal government is planning an increase to more than 2000 sites, there is a significant opportunity for PV in the global micro‐grid electrification context.
