Abstract
　As distributed generation systems (DGS) continue to play
an important role and have increasing trend on an electric power
system, the impacts of DGS on power system have become a
very important issue. In this thesis, an objective function and the
concept of system electric loss are first proposed to determine
the optimal placement of DGS in a connected power system.
The relationship between feeder length and allowable
penetration levels of DGS based on harmonic limit
considerations are then calculated. The amplification effect of
current harmonic distortion caused by underground cable of a
DGS is also presented and two practical wind power systems in
Taiwan are utilized to verify the effect. Simulated results show
that the length of underground cable have obvious effect on the
amplification of total harmonic distortion of current generated
by DGS.
