Applying event-based framework to support power system integration

Abstract

This paper describes a real life integration scenario of two power control systems. For that purpose we designed event-based framework and use it to create soft-real time gateway application service that facilitate integration of two complex, event-driven, distributed systems. The event-based framework uses publish-subscribe event delivery and supports asynchronous messaging, including asynchronous transactions. Extensible event-driven applications can be based on that framework. Event listeners and event type subscriptions could be added or removed at runtime. The framework simplifies application design and implementation because it solves concurrency related issues and access to shared resources by design-application developer does not need to deal with multithreading at all and still can implement flexible, multithreaded, thread-safe, event-driven applications. © 2012 Springer Science+Business Media B.V.
