LAN based data communication in modern energy management systems (EMS)
Werner Dieterle, Hans-Dieter Kochs, E. Dittmar · IEEE Transactions on Power Systems · 1996
The use of energy management systems (EMS) demands high reliability, real-time behaviour and more and more economical systems. The last demand requires use of inexpensive standard components, whenever possible. The following article discusses realization of EMS, especially system communication, with respect to these constraints. Problems due to conventional use of standardized communication protocols in distributed supervisory systems in general and highly-reliable systems in particular are shown. Multicast communication concepts are presented as solutions, using standardized protocols in a problem specific way. The concepts presented fulfill the necessity of using standard components as well as the specific demands towards EMS.
