Scalable and enhanced remote services for power system reliability estimation

Abstract

The principal objective of the research is to develop scalable and enhanced distributed services for power system reliability estimation. An innovative and comprehensive strategy has been implemented for power system reliability data representation, which is capable of accessing power system data from any data source and converting them to a common format using pre-defined XML document template. An XML annotation scheme is adopted for power system reliability data generation service. A Web enabled automation model has been formulated to upload reliability estimation services. A Service Oriented Architectural model using layered composition has been developed and implemented for generation system reliability analysis. Performance analysis has been carried out to compare the Round Trip Time, Throughput and the usage of resources with respect to different distributed models developed for power system reliability estimation and the results are reported. A secure and scalable Web application framework has been developed using SOAP communication for continuous monitoring of power distribution systems and maintenance of outage history information which is required for planning while further expansion. This model enhances the security of operational data of different power sectors in the deregulated environment and protects the history of outage information as the clients are not aware of the location of the operational database. The SOAP communication model uses sharable bean components and Web services to update the power system operators automatically with outage or restoration information due to data changes with respect to the operational status of the power systems. The service that resides in the database server is informed about the new information by triggering a function. The reporting facility is extended to various devices to enhance the reliable communication to avoid abnormalities. newline
