Kodiak Island: 98% #renewable Energy

Views: 231
Kodiak Island,
. . . 2nd largest island in the US, has a population of
. . . 15,000 scattered among 7 communities.
It gets its electricity from:
. . . . . . wind turbines, and
. . . . . . hydroelectric facilities,
. . . both of which typically fluctuate in their output.
To balance the system,
. . . it relies on a microgrid engineered, and installed by
. . . ABB, the giant Swedish/Swiss energy, and technology company.

“Remote locations like islands,
. . . may be rich in renewable energy sources,
but, the intermittent nature,
. . . makes their integration into the power grid a challenge.
ABB’s innovative microgrid solution,
. . . includes grid stabilization technology,
. . . that enables high penetration of:
. . . . . . renewable power generation, and
. . . . . . distributed control systems, that provide
. . . intelligent power management, and
. . . efficient hybrid power plant operation.”

The advantage of the PowerStore flywheel units,
. . . is that they can switch from:
. . . . . . full power charge, to
. . . . . . full power discharge, in less than
. . . 5 milliseconds.
Besides providing voltage, and frequency support, for the new crane,
. . . the PowerStore units will extend the life of the
. . . two 1.5 MW battery systems, and
. . . help to manage the intermittencies from the island’s
. . . 9 MW wind farm.
Battery performance tends to degrade after
. . . hundreds or thousands of charge/discharge events.
But, Flywheels do not.

Puerto Rico,
. . . might benefit greatly from such microgrid systems.
