Feasibility Analysis of a Mobile Microgrid Design to Support DoD Energy Resilience Goals
Abstract
This research investigates the feasibility of using mobile microgrids to increase energy resilience on Department of Defense installations. The primary question examined is whether a standardized mobile microgrid, constrained within an ISO TriCon container, can provide the necessary power for small critical sites with an average 10 kW load with similar resilience to a customized single load microgrid or emergency backup generator. Key assumptions for this research are that power outages may be accompanied by a fuel-constrained environment (e.g., natural disaster that restricts fuel transport), that an existing installation microgrid is in place, and that the risk of outages does not warrant the development of redundant customized single load microgrids for each critical load. Feasibility was examined by constructing an architectural design that attempts to find a satisfactory combination of commercial off-the-shelf components for battery energy storage, photovoltaic power, and generator power within the constraints of an 8 ft x 6.5 ft x 8 ft shipping container. That design was modeled and simulated over a two-week period using Global Horizontal Index solar irradiation data, and a randomized average 10 kW load. Results of the model were used to analyze the feasibility of the system to meet the load while reducing dependency on fuel resources. Trade-offs between a customized single load microgrid and standardized mobile microgrid are discussed.
