Abstract—The power systems industry has unprecedented changes in its structure every day. In the open market environment, entities like generation, transmission and distribution make new issues in power system operations and planning are inevitable. One of the major consequences of this environment is the greater emphasis on stable operation of power systems. This paper aims at the development of Service Oriented Architecture (SOA) based model for representing large interconnected power systems and its operations. An attempt has been made to test the proposed model for transient ‘stability analysis. The proposed SOA model includes Pre-Fault, During-Fault, Post-Fault and Swing Curve services which are accessible to the power system clients when the system is subjected to large disturbances. The stability services are configured and deployed in the service provider and then published in a registry for enabling universal visibility and access to the power system clients. A generalized XML based model for data representation has been proposed for exchanging data in order to handle interaction legacy power system applications in a service oriented environment. An effective SOAP based communication model is proposed to bind the power system stability services. The proposed model portraits the stability services in service oriented environment that provides a flexible, scalable and reliable infrastructure for representing and analysis of power system operations.
