Microgrids: Efficient, Secure, Resilient
February 9, 2012
A number of institutions across the country, including many military bases, are looking at insuring reliable, resilient and efficient electricity production in the age of peak oil and terrorism. Above, a Sandia Lab video describes the concept.
This technology is being pioneered, like transistors, computers, microchips, jet engines, global positioning, the internet, and now renewable energy, by the military, as a template for future wide civilian deployment.
Below, The University of California at San Diego demonstrates a working example.
Rocky Mountain Institute:
Rocky Mountain Institute visited the University of California, San Diego to study and document the “microgrid” that controls and integrates electricity supply and demand on the campus. UCSD’s microgrid is one of the best examples of an electricity network that provides local control yet is interconnected with the larger electricity grid.
At UCSD, the microgrid provides the ability to manage 42 megawatts of generating capacity, including a central cogeneration plant, an array of solar photovoltaic installations and a fuel cell that operates on natural gas reclaimed from a landfill site. The central microgrid control allows operators to manage the diverse portfolio of energy generation and storage resources on the campus to minimize costs. In addition, the campus can “island” from the larger grid to maintain power supply in an emergency, as in the case of the power blackout that struck parts of Southern California, Arizona and Mexico in September 2011.
The microgrid at UCSD provides a living laboratory to experiment with integration and management of local resources and to optimize the use of these resources in interaction with market signals from the larger grid.
