Extending IEC 61968 to Support Wide Area Demand Response Program

Demand response provides many benefits in financial and operational aspects for the power user, load management unit and the grid operator. In this paper, we have extended the traditional specification in distribution system automation IEC 61968 to support further demand response service. There are some basic modules and packets have been defined to update traditional metering device, and also the newly added controlled object have been involved. At last, we have take time of use price to illustrate the performance of a wide area demand system by integrating a new controlling algorithm and the results show that it can significantly improve the performance of electricity devices in a home area network.
