Low Frequency EMC and
Power Quality
Development of standards towards convergence

FIGHTING CLIMATE
CHANGE MEANS MORE
ELECTRONICS In addition to power electronics, there
is also an increased use of electronics
for supervision and control.
Electrification clearly facilitates our
progress toward a resource-efficient
and climate-friendly energy system.
The share of electricity in total energy
demand is projected to increase
drastically in all the decarbonasation
scenarios of the recent European
Union (EU) Energy Road Map 2050 1
(Figure 1). Smart Grid is More than
Networks Wind and solar power are examples of
expanding technologies for renewable
power. Germany now has 25 gigawatts
of installed solar power 2 . Electric
vehicles, light emitting diode lamps
and heat pumps are energy efficient
electrical technologies of importance
when fighting climate change. In
virtually all such technologies, electrical
energy is passing power electronics.

The smart grid is a very topical
issue. The term is widely used by
many, especially politicians. Now
the International Electrotechnical
Commission (IEC) has defined the
concept of smart grid 3 . The definition
states that the smart grid is an electrical
energy system that uses information
technology. The smart grid is thus not
only related to electrical networks,
but to entire the power system. With
smart grid technologies as well as
power technologies for renewables and
improved energy efficiency, there is an
increased use of electronics. We see
growth in the use of power electronics,
as well as electronics for information
technologies. www.incompliancemag.com
