In the last years the integration of DG in the distribution
network has significantly increased. With this increase in
the injection of energy from decentralized generators the
grid faces new challenges. Energy surplus coming from RES
may produce a reverse power flow in the network altering
the way conventional power systems operate. Due to this
the presence of overvoltages and voltage unbalances will be
more commonly seen in the grid. Classical compensation
methods are typically used in the transmission level. However,
this methods assume that the network has a high X/R
ratio and SCR. In order to compensate for this problems
in the distribution network a new approach has to be made
considering the characteristic of the distribution network
such as the low X/R ratio.
In this thesis different methods for voltage unbalance compensation
using the grid connected converter of a DER are
analyzed. The operation of the methods is verified using
Power Factory 15.
