Performance Analysis of Demand Response System on top of UMTS Network
Carleton University, Ontario, Canada. October 2008.

Demand Response mechanisms help power grid operators to dynamically manage demand from customers and maintain a stable power supply level. With the development of 3G technologies, many services can co-exist simultaneously. A common 3G technology is UMTS, currently being deployed in a number of countries. It is used as the platform for our task.

We explore the impact of DR Service on other services within the UMTS framework: Compared to TCP, UDP as a transport protocol is a better choice for DR Service; Different physical environments for DR application are evaluated; The impact that DR Service has on RRC Service can be limited to minimum if the frequency of DR Service is controlled.

XML-based DR application introduces redundant data, larger DR messages have a more significant impact on RRC Service. XML compression technologies can reduce the size of DR messages to 20%-50% of the original documents.
