—This paper presents a new approach to power system automation, based on distributed intelligence rather than traditional centralized control. The paper investigates the interplay between two international standards, IEC 61850 and IEC 61499, and proposes a way of combining of the application functions of IEC 61850-compliant devices with IEC 61499-compliant(More)
This paper proposes solutions for distributed protection applications, to improve current and design of future protection schemes. This solution utilises advantages of fast and reliable peer-to-peer communication of IEC 61850 and interoperability and configurability of IEC 61499. The integration of the two standards improves protection schemes by decreasing(More)
This paper proposes standards' based software and communication platform for implementation of distributed grid intelligence in FREEDM system. This enables system level design for distributed application and consistent mapping to the interfacing hardware. The system becomes scalable, re-configurable and easily maintainable. Applying IEC 61499 standard for(More)

The present study determines the optimum value of series compensation to improve the transient stability of a multi-machine power system using both dynamic fuzzy Q-learning(DFQL) controller and particle swarm optimization(PSO) based bang-bang controller. The DFQL based controller are suitable for continuous control and the bang-bang controller for discrete(More)
The restructuring of the electricity sector into competitive entities introduces new paradigms to the planners and the operators of the system. One such issue that needs to be evaluated is the decomposition of voltage security margin usage over individual energy transactions. Such a procedure would form the technical basis towards setting up voltage(More)
