However, in case of energy crisis the most important
are people's houses and industry. It has been proved for
many years that people's prosperity and life quality are
closely connected with power systems' development and
electrification's level [12]. Hence, in sphere of author's
consideration the most important power consumers are
human beings and their houses. The question is how to
feed houses with electricity - small town, village,
commune or small island - using only primary energy
carriers available on the spot. Hence, an idea of microgrid
was developed - small power system, automatic,
autonomous and balanced.
Besides the expecting energy crisis, motivation to
research is also necessity of reelectrification of some areas
and increasing RES utilization in power production.
For the sake of disadvantages of RES such as uncontrolled
and unforeseeable power production profile, their
independent utilization as primary power source in the
power system is impossible without a significant drop of
power quality and reliability. For Poles it means, in
practice, Christmas spent by candles light. Hence, power
production hybridization can be the best or the only way
to solve the problem.
