Abstract
This paper gives emulation studies on the communication traffic characteristics of the future Smart Grid's Fast Automated Demand Response (FastADR) Aggregation for widely-distributed office buildings' facility loads. A real-time realistic emulation experiment system was developed consisting of 80 devices in which actual FastADR aggregation communication software was installed. The Internet traffic conditions were emulated by burst IP packet losses and round trip time delays. Our experimental studies showed more
severe variation of aggregation data transmission time than expected before. In an example case of power curtailment, i.e., negawatt of 5 MW from 50 buildings, more than 60 seconds will be needed to complete a sequential aggregation web services with each building's gateway.
