To a baseline diesel-generator-only system. The CUBE was tested to demonstrate fuel savings as well as power quality relative Up to provide a flexible platform that can be modified to meet specific needs. Protection necessary to integrate various power sources and was built from the ground The CUBE provides the power conversion, distribution, and The cornerstone of the hybrid power system is the Consolidated Utilityīase Energy (CUBE) system. Army Rapid Equippingįorce and the Expeditionary Energy and Sustainment Systems to provide power to forward NREL developed a PV-battery-diesel hybrid power system for the U.S. Hybrid microgrid testing, including the distribution integration of wind turbines, PV, dynamometers, loads, and energy storage Programmable DC power supplies to emulate photovoltaic (PV) arrays and battery banks Programmable AC power supplies (grid simulators) to emulate the grid-tie as well as Power hardware-in-the-loop testing of microgrid hardware Microgrid system modeling and simulation on timescales of electromagnetic transientsĭevelopment of power electronic converters and control algorithms for microgrid integrationĬontroller hardware-in-the-loop testing, where the physical controller interacts with a model of the microgrid and associated Interruptions or, for remote areas, where there is no connection to the larger grid. InĪddition, advanced microgrids allow local assets to work together to save costs, extendĭuration of energy supplies, and produce revenue via market participation. Renewables, and storage-to keep the local grid running even when the larger grid experiences Improve customer reliability and resilience to grid disturbances.Īdvanced microgrids enable local power generation assets-including traditional generators, It can connect andĭisconnect from the grid to operate in grid-connected or island mode. A microgrid is a group of interconnected loads and distributed energy resources thatĪcts as a single controllable entity with respect to the grid.
