Regulation and protection have been the major issues to prevent the consumers from enjoying good quality of service (QoS) at reasonable prices, for example, electricity and long distance call service. Deregulation in such industries started in early 1970s and have achieved significant results in, for example, telecommunication industry. The deregulation in telecommunication was mainly focused o...

The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent built up in the decades following World War II with a peak in investments around 1960-1980. This means that the flotilla of power transformers is now starting to reach projected lifetime of around 40 years. During the last couple of decades there has also been an ongoin...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

Recent technology improvements in small generators and energy storage devices have provided new opportunity for dispersed energy resources at the distribution level. At the same time, deregulation has encouraged a more decentralized approach to power delivery. This paper proposes some approaches to power system operations and control at the distribution level. A methodology for system security ...

Data Communications has always played an important role in the operation of the utility system from high-speed relay communications to the recent expansion in “intercontrol center” data sharing. The increasing incorporation of digital devices throughout the utility enterprise as well as the forces of deregulation are driving utility communications into new realms with new requirements and parad...

Power industry deregulation trend and proliferation of digital electronic devices are deeply affecting operations of power utility companies. Engineering departments, in particular, must deal with increasing complexity of existing applications as well as with emergence of new applications. Such an environment, creates many new challenges for protection system engineers. Use of new business mode...
