Plug-in hybrid electric vehicles (PHEVs) represent one option for the electrification of private mobility. In order to efficiently integrate PHEVs into power systems, existing organizational structures need to be considered. Based on procedures of power systems planning and operation, actors are identified whose operational activities will be affected by PHEV integration. Potential changes and ...

Background: The increasing penetration of a massive number of plug-in electric vehicles (PEVs) and distributed generators (DGs) into current power distribution networks imposes obvious challenges on power distribution network operation. Methods: This paper presents an optimal temporal-spatial scheduling strategy of PEV charging demand in the presence of DGs. The solution is designed to ensure t...

Electric utilities are increasingly aware of the potential of IT and its impacts on their business operation. However, in order for a utility to be able to translate all these potentials into real benefits, an IT strategy is needed to manage the developments, acquisitions, and the utilization of IT systems within the organization. Today, quite a few electric utilities have prepared or are in th...

The electric power is one of the major operating expenses in data centers. Rising and varying energy costs induce the need of further solutions to use energy efficiently. The first steps to improve efficiency have already been accomplished by applying virtualization technologies. In this paper, we address the problem of energy efficiency in data centers. Efficient and scalable power usage for d...

the aim of this study was predict organizational citizenship behavior prevalence based on the staff perception of type of organizational structure in fars regional electric and power distribution companies (frepdc). statistical population consisted of the entire staff of fars regional electric and power distribution companies amongst 232 participants selected using random classification method....

This article presents a critical analysis of all the major pathways to produce hydrogen and to utilize it as an energy carrier to generate heat or electricity. The approach taken is to make a cradle to grave analysis including the production of hydrogen, the conversion of hydrogen to heat or electricity, and finally the utilization of that heat or electricity for a useful purpose. This methodol...

Facing the recent growing concern about the environment and electric power crisis triggered by the Great East Japan Earthquake, efficient use of energy has become an important issue. A smart grid that is a next-generation electric power network is expected to be one of the solutions and to form an enormous market. Aiming to enter this new smart grid market, Sumitomo Electric Industries, Ltd. es...

this paper is concerned with the estimation of total factor productivity (tfp) growth for the iranian electric utilities during the period 1980-1993 on the basis of panel data. a translog cost function is used which accommodates firm - specific variability through a one - way error component model. the results show that the iranian electricity supply industry experienced increasing returns to s...
