The United Nations Foundation has published a seminal report on microgrids, Microgrids for Rural Electrification: A critical review of best practices based on seven case studies. They focus on small remote microgrids for energy access. This is one of the four major microgrid markets as defined in HOMER Energy CEO, Dr. Peter Lilienthal’s article, “How to Classify Microgrids: Setting the Stage for a Distributed Generation Energy Future“, which the UNF document cites several times.
