IEEE Power Electronics Magazine - December 2016 - 12
For example, the emergence of power
electronic-based transmission and
distribution technology as a driving
force for grid modernization is coinciding with fundamental changes that
are taking place in the ac power grid.
Whereas the old conventional grid
was scalable and the stability easily
manageable, modernized power systems are now plagued by sub-, super-,
and interharmonic resonances that are
caused by the introduction of renewables and power electronics components. We are now in a phase in which
we often solve the problems caused
by power electronics by adding more
power electronics. Therefore, it is
necessary to go back to the drawing
board to figure out how to build
power systems that are softly coupled
to the sources of inertia, i.e., synchronous machine rotors and large batteries, and where either harmonics are
eliminated or employed constructively
instead of acting as sources of pollution and causing instability.
the lighting Up a Billion
smiles competition
The goal for the new initiative project
is to reach the global tipping point for
small renewable energy systems, and
we foresee that a new disruptive
power system technology will emerge
due to tremendous advances and cost
reduction in photovoltaic, battery, and
communication technologies. A wireless power web that operates on wireless energy from the sun and uses
wireless communication to the cloud
can become the entry-level power system, benefiting communities in emerging economies that face extreme energy poverty. It can provide a low-cost
alternative to the traditional wired
power grid in low population density
areas around the world, and it is an
environmentally friendly alternative
that does not require a large capital
investment. Connecting energy devices with copper cables remains possible, but it becomes an optional feature
because the management and control
of the energy devices are done
through the cloud.
The Lighting Up a Billion Smiles
competition targets the development
of appropriate wireless power web
technologies for an estimated 3 billion people across the globe in regions
such as Africa and India, where there
is no access (off grid) or extremely
limited access (poor grid) to electricity. Rather than be prescriptive about
a solution, PELS feels it is critical to
harness the creativity, talent, and passion of the global community and to
have them be collaboratively involved
in finding one or multiple solutions
that can achieve the transformative
impact desired. A global competition
in combination with mash-up events
help provide a common context and
framework as well as the basis for
broad collaboration.
International technology
road Map for wide-Bandgap
Power semiconductors
In the "President's Message" column in
the June 2016 issue of this magazine, I
reported the formation of the International Technology Road Map for WideBandgap Power Semiconductors
(ITRW). We hit the nail on the head
with the timing. The founding meeting was in December 2015, shortly
after it was decided to discontinue the
