Abstract

Power quality means to maintain or compensate
the nominal size and frequency of the near sinusoidal nominal voltage and
current of the power system. As an undesirable condition in the power quality,
the energy loss leads to a decrease in the efficiency of the system and the
failure in sustainability in energy. In most cases, the control of the power
quality means that the voltage is controlled, ie, the frequency balance. This
is because in most cases the tension can be more easily controlled from the
current. More specifically, power quality can be explained by some parameters
such as continuity of service, change of voltage magnitude in transient
voltages and currents, and harmonic content. To define the importance of power
quality problems, we can say that poor power quality leads to unnecessary power
and economic waste. This also directly affects the risk of reliability in
energy. In addition, it creates a financial burden for suppliers and consumers.
Unstable voltage and frequency often create problems with the power flow in the
transmission line. Several methods are used to solve basic power quality
problems. In this study, energy quality solution methods, especially reserve
requirements, have been examined and solution suggestions are presented.
