A software architecture for power market supporting system and reengineering of legacy EMS

In this paper, a heterogeneous software architectural style is designed for the Web-based software system to support an electronic commerce solution for deregulated power markets, which is flexible for various power market structures and extendible for the fast-changing industry environment. A wrapping technique is designed to transfer the legacy energy-management system (EMS) modules into reusable components for the power market supporting software system.
