One of the outcomes of the continuous research on the evolution of distributed computing is the Web services. The aim of this paper is to represent Power System data effectively in XML in order to improve the interoperability and to develop an enhanced distributed model for unique XMLised Power System Data generation for solving various Power System applications in heterogeneous environment. Power System industries are now increasingly becoming privatized and hence the system data is becoming increasingly distributed, with more constrained and complex operational and control requirements. Because of the complex physical connectivity of the power systems, all levels of industry like generation, transmission, distribution and market need proper operational and equipmental data. As expected, the data to be shared between different power system applications is huge and hence it is vital to have an efficient and reliable data generation model to reduce more human efforts and to have the data in a secure and compatible form. The developed JAX-RPC-based model has the capability to generate the data dynamically in XML, fetching the power system data from various sources such as database, text file, etc. The standards such as XML and SOAP enable software design based on loose coupling which reduces restriction and eliminates similarity requirement between coordinating applications.
