Software architecture for delivering power system applications using Software-as-a-Service model

Abstract

In a deregulated system designed to support open access, decision making has to be transparent and it requires participation of many players whose behavior is governed by diverse interests from profitable trade all the way to security in system operation. In particular, we foresee that decision support tools should be so deployed that they can be accessed anywhere and at any time. This led us to work on introducing Software-as-a-Service model for power system computation - using the internet to provide access anywhere and at any time. We consider different challenges in terms of usability, scalability and security when it comes to delivering required functionality over the web using Software-as-a-Service model. The proposed software architecture called Web Delivery of Network Applications (webDNA), addresses various issues involved in delivering these applications over the web.
