这封信报告了GridShares的设计和试点安装，该设备旨在缓解孤立的村庄规模的小型电网因高峰用电而造成的停电。一个由作者和合作伙伴组织组成的团队在不丹的Rukubji村设计、建造和实地测试了GridShares。GridShare采用了一种创新的方法，通过使用低成本的设备来减少停电，该设备将电网的状态传达给用户，并在严重停电发生之前调节使用情况。这种需求侧解决方案鼓励用户在一天中更均匀地分配大型电器的使用，使电力有限的系统能够为这些社区提供可靠的长期可再生电力。2011年夏天，每个家庭和企业都安装了GridShares，连接到Rukubji微型水电微型电网，该电网为大约90个家庭提供40千瓦额定容量的微型水电系统。该装置伴随着广泛的教育计划。安装GridShares后，主要因在准备膳食时使用电煮食器具而导致的严重电力不足的发生率及平均时间减少超过92%。此外，大多数接受调查的居民表示，现在他们更确定他们的大米会煮得很好，他们会建议在面临类似问题的其他村庄安装GridShares。
This letter reports on the design and pilot installation of GridShares, devices intended to alleviate brownouts caused by peak power use on isolated, village-scale mini-grids. A team consisting of the authors and partner organizations designed, built and field-tested GridShares in the village of Rukubji, Bhutan. The GridShare takes an innovative approach to reducing brownouts by using a low cost device that communicates the state of the grid to its users and regulates usage before severe brownouts occur. This demand-side solution encourages users to distribute the use of large appliances more evenly throughout the day, allowing power-limited systems to provide reliable, long-term renewable electricity to these communities. In the summer of 2011, GridShares were installed in every household and business connected to the Rukubji micro-hydro mini-grid, which serves approximately 90 households with a 40 kW nominal capacity micro-hydro system. The installation was accompanied by an extensive education program. Following the installation of the GridShares, the occurrence and average length of severe brownouts, which had been caused primarily by the use of electric cooking appliances during meal preparation, decreased by over 92%. Additionally, the majority of residents surveyed stated that now they are more certain that their rice will cook well and that they would recommend installing GridShares in other villages facing similar problems.
