Mitigation of Power Quality Issues in Hybrid Wind/Diesel System using UPQC

The domestic consumers in the remote areas not served by the main electrical grid network, diesel generators are the usual choice for power supply. As a result, plenty of servicing and maintenance needed onto these diesel generators. Thus, we proposed an idea of introducing wind turbine working together with the diesel generators to form a hybrid power system but after connecting wind system with the diesel there are certain power quality issues are created to reduce that issues author proposed a system by introducing UPQC in hybrid system. In such system The DG converters (with storage) and the shunt part of the UPQC Active Power Filter (APFsh) is placed at the Point of Common Coupling (PCC). The series part of the UPQC (APFse) is connected before the PCC and in series with the grid. The dc link can also be integrated with the storage system. An intelligent islanding detection and reconnection technique (IR) are introduced in the UPQC as a secondary control. Hence, it is termed as UPQCµG −IR.
