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...

With the maturing of the Utility Communication Architecture (UCA), utilities are beginning to implement substation protection and control systems that are based on this technology. This paper describes such an implementation for the control of the Bateias 525kV substation on the COPEL power system in Brazil. In particular, the paper will describe the customer’s requirements and expectations wit...

A complete reconstruction program was started at the electrical substation of the Paks Nuclear Power Plant to assist the Hungarian high voltage network to join the European network. At the operator level a new, PC-based SCADA (Supervisory Control and Data Acquisition) system was introduced. An AI-based, intelligent advisory system was developed and embedded into the SCADA system. The first part...

System reliability indices deal with the adequacy of overall system supply and indicates behaviour response. The index express interruption statistics in terms customers which can be an individual, firm, or organization that purchases electric services at one location under rate classification, contract schedule. include: Average Interruption Frequency Index (SAIFI), Duration (SAIDI), Customer ...

The aim of this study was to assess the validity and reliability of a Turkish version of the rapid eye movement sleep behavior disorder questionnaire (the RBDSQ-T) for identifying patients with rapid eye movement sleep behavior disorder (RBD) and to ensure that this tool can be applied in Turkish language. Three groups were enrolled to validate the RBDSQ-T: 78 healthy controls, 17 patients prev...

This paper presents an overview of the evolution in structural and geotechnical design practice over the past half a decade or so in relation to how uncertainties are dealt with. For the general reader who is encountering reliability-based design (RBD) for the first time, this would provide a valuable historical perspective of our present status and important outstanding issues that remain to b...

binary decision diagram (bdd) is a data structure proved to be compact in representation and efficient in manipulation of boolean formulas. using binary decision diagram in network reliability analysis has already been investigated by some researchers. in this paper we show how an exact algorithm for network reliability can be improved and implemented efficiently by using cudd - colorado univer...

in this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. the objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. the combination of firefly algorithm, parti...
