Electricity Demand as Frequency Controlled Reserve (DFR

Speaker: Assistant Professor Zhao Xu, Centre for Electric Technology, Technical University of Denmark

When: 2008-05-15 17:00:00

Venue: 78-621

Host: Prof Tapan Saha

Abstract:

Using demand as frequency controlled reserve (DFR) is an emerging
technology that can enhance the security in power system
operation. The basic premise of the DFR technology is that
conventional reserve in power systems can be slow and costly, while
many electricity demands can be shortly interrupted in response to
frequency variations without causing discomforts or harms to the
customers and themselves.

Many advantages can be achieved by using DFR such as low cost, fast
responding speed, well distributed at feeder levels, and pollution
free etc. Most importantly the DFR will facilitate increased
penetration of wind power into power system foreseen by utilities
and governments, e.g. the new Danish Energy Policy has suggested 50%
wind penetration in Denmark by 2025.

On the other hand, many questions with the technology exist, yet to
be answered. In this presentation, a comprehensive introduction of
the technology will be given. Issues such as system frequency
quality analysis, DFR control logic design and the impacts on the
grid will be covered. In addition, the future development of the
technology will also be discussed.
