Abstract

This paper examines the practical application of the Unscented Transform (UT) method in carrying out load flow studies in distributions systems with embedded generation and unbalanced loading. A hybrid ladder network based backward/forward sweep technique was employed in solving the distribution system load flow. The performance of the load flow technique plus the UT method is demonstrated using a real 44-Bus unbalanced distribution system with a proposed wind farm which is located in Samsun, Northern Turkey. Results obtained were compared with those from the Monte Carlo Simulation method while the effect of the wind farm on the existing network was also evaluated.
