The Power Of Data: How Software Is Helping Keep Iceland’s Lights On
By Julie Khoo – There are many reasons to visit Iceland. This former Viking stronghold is now the most peaceful country and home to the happiest and most literate people in the world — one in 10 Icelanders on average reportedly has published a book.

A nation of glaciers, volcanoes and waterfalls, Iceland is also, at least metaphorically, one of the greenest places, generating all of its electricity from renewable sources such as hydropower and geothermal energy.

The grid receives electricity from generators that move at a constant frequency, just like the merry-go-round. When a power-hungry load suddenly disconnects from a high-inertia grid with lots of generators, the grid frequency will barely change.

But when a generator or load goes offline in a low-inertia grid like the one in Iceland, Landsnet has to act quickly to return the frequency to its normal level.

This can be a real headache. If the frequency drops or climbs too quickly, it can knock down parts of the grid and cause power failures. It can even cause a geothermal power station to automatically disconnect from the grid to protect the equipment from large stresses. Dramatic changes in frequency can also create “electrical islands” as different areas on the grid react to the changes. This can lead to blackouts. more> https://goo.gl/LyyN60

This Deconstructed Locomotive Will Power Nigeria’s Economy

GE – Nigeria has fast become Africa’s largest economy, but its infrastructure is still lagging.

The electrical grid is so unpredictable that many businesses use natural gas to produce their own power. That’s why GE engineers recently converted a powerful diesel engine from a locomotive into an efficient stationary power plant that can produce enough electricity to supply a factory, or 6,600 Nigerian homes.

The project was also an exercise in FastWorks, a set of tools and principles currently transforming GE culture into a leaner and faster company working close to customers. more> http://tinyurl.com/l9zvfj9
