As Plug-in Hybrid Vehicles (PHEVs) take a greater share in the personal automobile market, their penetration levels may bring potential challenges to electric utility especially at the distribution level. This paper examines the impact of charging PHEVs on a distribution transformer under different charging scenarios. The simulation results indicate that at the PHEV penetration level of interest,...
The power system especially at the distribution level is prone to failures and disturbances due to weather related issues and human errors. Having distributed generation (DG) as a backup source ensures the reliability of electric power supply. Therefore, distributed generation is expected to play a key role in the residential, commercial and industrial sectors of the power system. In this paper, the...
Data mining refers to extracting or ldquominingrdquo knowledge from large amounts of data. Thus, it plays an important role in extracting spatial patterns and features. It is an essential process where intelligent methods are applied in order to extract data patterns. In this paper, we have proposed a technique with which it is possible to detect whether a given data set is erroneous. Furthermore,...
In this paper, we propose a unifying framework for efficient generation of combinatorial objects by giving recursive definition of an abstract combinatorial class. The definition can be instantiated to an array of specific combinatorial classes by specifying the framework parameters appropriately. Our framework defines a rooted spanning tree over a representative graph of that abstract combinatorial...
