1 Background
Energy systems around the world are going
through incredible transition, reflecting the
global shift from traditional fossil fuel-based energy
sources like coal, oil and natural gas renewable
and sustainable energy sources like wind, solar
and nuclear energy. the
energy system the future, power flow likely to
be bidirectional many parts the power system,
with generation coming from large number of
geographically distributed, smaller generation
units. many developed nations, most the
electricity system infrastructure was put place
during the 20th
century and now reaching the
end its design life. But the current rate of
overhaul, would take several hundred years to
fully replace [1]. Traditional power systems
were based unidirectional power flow and a
relatively small number large generators, while
this decentralization requires more flexible and
adaptive electricity grid infrastructure.
At the same time electricity systems wrestle
with the way electricity made and distributed,
the fundamental nature energy consumption
is changing: many energy loads that were
traditionally supplied fossil fuels are being
“electrified”, which will pose further challenges and
produce massive changes electricity generation,
transmission and distribution. Throughout the paper, the term “power
systems” refers electricity distribution systems. This transition largely driven
by factors such the need reduce greenhouse
gas (GHG) emissions, search for cheaper energy
sources and concerns about the unsustainability
of traditional energy supplies. One the most
obvious changes the shift from large, centralized
power plants more decentralized and distributed
renewable energy generators like solar generators
and wind turbines.
Electricity systems are one the largest
components transformation that impacts
every aspect the way electricity generated,
distributed, and consumed. This transition
is perhaps more accurately described a
transformation the way energy systems operate,
as around the world every aspect how energy
is produced, distributed, consumed, bought and
sold changing.

Medium voltage direct current (MVDC) grid
technology could assist with many these
challenges.
All the changes described above are happening on
top electricity systems that many countries
are quite old and/or already operating maximum
