Abstract

The DG placement algorithms perform the optimal placement and sizing in distribution system. But it only considers the real and reactive power loss minimization. The analysis is static. The DGs are generally dynamic in nature as they are renewable resources. But the loads connected in the DGs are not only linear loads. Many loads at the feeder are non-linear. In this paper the unified power quality conditioner (UPQC) is interfaced with PV (Photo Voltaic) and wind generators. The current reference generation technique is used for series converter and shunt converter by using this hybrid combination. This takes care of all types of voltage sags and swells. The real and reactive power both is controlled from PV and wind to grid. The system is considered as a standard distribution feeder system. The 230V feeder system is considered here for testing these dynamics.
