Performance monitoring of energy flow in the Power Transmission and Distribution System using Grid Computing.(Report)

INTRODUCTION

The Growth of the Internet, along with the availability of powerful computers and high-speed Networks as low-cost commodity components, is changing the way scientists and engineers do computing, and are also changing how society in general manages information. Grid Computing has been identified as an important new technology by a remarkable breadth of scientific and engineering fields as well as many commercial and industrial enterprises. Grid Computing is a form of distributed computing that involves coordination and sharing of computing application, data storage or network resources across dynamic and geographically dispersed organizations. In short, it involves virtualizing computing resources. (2) The Grid is defined as

1. The flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions and resources (4),(5),(6)]

2. A type of Parallel and distributed system that enables the sharing, selection and aggregation of geographically distributed autonomous resources dynamically at runtime depending on their availability, capability, performance, cost and users quality of service requirements(1)

While the notion of grid computing is simple enough, the practical realization of grids poses a number of challenges. The key issues that need to be dealt with are security, heterogeneity, reliability, application composition, scheduling, and resource management (1). The Microsoft .NET Framework provides a powerful toolset for all of these, in particular support of remote execution, multithreading, security, asynchronous programming, managed execution and cross-language development, making it an ideal platform for grid computing middleware. Alchemi (3) is a windowsbased desktop grid computing framework implemented on Microsoft .NET platform and developed at the University of Melbourne. Alchemi is implemented on top of the Microsoft .NET framework and provides the runtime machinery of constructing and managing desktop grids. It also provides and object oriented programming model along with web service interfaces that enable its services to be accessed from any programming environment that supports SOAP-XML abstraction.

While transmitting and distributing power to meet the consumers demand, Power losses occur in the EHV, HV and LV lines and also in the transformers. This technical loss in the power system is an inherent characteristic and it cannot be totally eliminated but can be reduced to an optimum level which will increase the revenue when monitoring and controlling of lines are done as and then by using the …
