The Next Generation of Electrical Workers: Microgrid Robots

microgrid robotsMicrogrids can provide power in remote, rugged. and even dangerous places. Problem is, you’ve got to put people in risky situations to build the microgrids – unless you send robots out to do the job.

Researchers at Michigan Technological University are hard at work creating these microgrid robots, a creation that could have a far reaching impact on how we restore power after disasters.

A team led by Nina Mahmoudian,  assistant professor, has put together a proof of concept for  robots that can traverse war zones or storm-ravaged terrain to build a mobile microgrid.

Robots now assist recovery efforts in other capacities following natural disasters. So it occurred to Mahmoudian: why not take robot capability one step further and have them restore power?

Called autonomous power distribution, the process uses a robot team that travels – even underwater – avoiding obstacles and debris that might make the going tough, if not impossible, for a human.

A video demonstration created by the lab shows in simple terms how it would work.  A lab-scaled robot powered by a battery travels to its designated location, finds a load source, and connects to it. A second robot then connects a power wire to the first through an electromagnetic connector. It pulls the wire to a power source, while keeping the connection secured to the first robot. A flag waves once the connection has been made. The robots avoid obstacles in their path with the use of  infrared sensors.

As a next step, the lab hopes to secure funding to establish a robot microgrid in real size and make it replicable with any number of robots. All aspects of it would be mobile, and it could establish itself in one location, then extend to another.

For example, during a natural disaster, the robots might build a microgrid at a hard-to-reach communications tower to restore cell phone service.

“There are some places that are so devastated, you cannot reach them. If we deploy robots, and they don’t need human intervention, and can establish this on their own, for the rescuers who are focusing their efforts on finding people,  it will be a big advantage,” Mahmoudian said.

Mahmoudian foresees mobile microgrids being used not only in disaster relief, but also for military purposes. Soldiers could travel to an operation with a lighter load if they send robots out in advance to put in place needed electrical sources.

“This can be used for establishing a power grid for soldiers before they arrive,” she said. “This will really increase the pace of the operation and make it more secure.”

Mahmoudian also believes robots eventually may assist with line repair during snowstorms  – “if we can get the technology to where they have arms and they can reach and recognize the failure.”

Science is at a point where it can build robots capable of many microgrid building tasks; the hard part is integrating the various pieces into a robot microgrid. It’s an “interdisciplinary” problem, Mahmoudian said.  The researchers  “can solve problems of mobility, reach, or power electronics on their own. But bringing mobility, power electronics and the underlying controls into one system presents the biggest challenge.”

The proof of concept was funded through the university’s Center for Agile and Interconnected Microgrids. As a next step, the research team hopes to establish a microgrid in real size and is seeking grant money for the basic research.

    They have been building cars etc etc etc, why not microgrids?


    If micro-grid technology is capable to reduce mining operations, it will be treated as friendly to ecology and viceversa.
