Microgrid modular design for tribal healthcare facilities: Kayenta health center used as guidance for concept model for Navajo Nation

This paper describes the wintertime experimental process and detailed information related to a 100KW PV system case study at the Kayenta Health Center, which is located in the Navajo Nation. Information about the PV system performance, the load demand of the power system at the facility, and additional field observations during wintertime supplements previous experimental data obtained during the summertime. Seasonal experimental data validated with theoretical data available for the zone, the facility, the systems and the equipment is used to develop a concept model for the actual implementation. Targeted information about harmonics provides insight about specific features of the model. Modeling and simulation tools will support the acquisition and design processes as well as the implementation of the microgrid in a tribal health care facility on the IHS New Construction Priority List. The concept model is adjusted such that the actual implementation of the microgrid will enhance the power quality, result in the design of optimum power system, produce energy savings and reduce environmental pollution.
