POWER QUALITY MEASUREMENTS PERFORMED ON
WIND FARMS IN TURKISH POWER SYSTEM
ABSTRACT
The wind farm integration may cause power quality concerns in power systems.
Integration of large scale wind farms into power systems presents some challenges
that must be addressed such as system operation and control, system stability, and
the power quality. Therefore, determining how much the power quality would be
affected by fluctuant power production and by the connection of the wind turbines
to the power system is the most important issue. Turkey has the highest share in
technical wind energy potential in Europe. However the installed wind power ca-
pacity is only 0.20 % of total economical wind potential. According to Energy
Market Regulatory Authority (EPDK) reports, new wind power plant license appli-
cations are reached to 78 GW by the end of the November 2007 [2]. Up to now,
only 2 GW of the total license applications was permitted by Energy Market Regu-
latory Authority. In this paper, the effect of wind farm is investigated by means of
power quality in the transmission network. The power quality measurement results
show important indications about the real effects of the integrated renewable gen-
erations on the power system.
