Operations analysis of wind penetration into distribution systems using PDLF

Wind Turbine (WT) generation sources have assumed an important role in the generation supply mix in many countries and its importance is continuously increasing. However, since wind generation is dependent on wind speed at a given instant, it is difficult to predict the operational aspects of systems with WTs in advance. This intermittent nature of wind generation makes its operation and planning a complex problem and there is a need for the associated mathematical models to consider this uncertainty appropriately. This paper presents a comprehensive analysis of the effects of wind generation in distribution systems using a Probabilistic Distribution Load Flow (PDLF). The analysis provides an insight into the effects on system losses, voltage regulation and substation power import due to wind generation at different locations.
