IEC 61850-based communication and aggregation solution for demand-response application

This paper presents an IEC 61850 standard-based communication and aggregation solution for Demand-Response application, which allows end devices automatically detected, configured and integrated to the overlying Demand-Response system, thereby greatly increasing the integration efficiency, and making large scale of deployment feasible. This communication solution is dedicated to one community-wide Demand-Response application designed for a residential area near an industrial installation in Sweden. The community-wide Demand-Response application will be briefly explained in the paper, however, the main focus of this paper is the communication solution and IT system implementation for this application. The communication solution is realized by the unconventional use of IEC 61850 standard, and implemented in a hierarchical structure consisting of SCADA, communication gateway and low cost micro processor-based spatial heating controllers.
