1. Wind Integration and DR PNDRP Dec. 5, 2008
Ken Corum

2. What’s the Problem with Wind?
Wind requires increased “ancillary services”
What are ancillary services?
Spinning reserve
Non-spinning reserve
Regulation
Load following
Black start
Voltage Control 2

3. What are “Regulation” and “Load Following?”3

4. 4

5. LF -
Reg - 5

6. Regulation Needed every hour of year Quick, automatic response
Must go both ways (“reg up” and “reg down”)
Wind doesn’t increase need for reg much 6

7. Load Following Scheduled w/in hour Reduces regulation requirements*
Must go up and down
Needed every day if not every hour
Wind increases requirements
*If reg is cheap and abundant enough, LF not needed 7

8. So What Kind of DR Might Work?
Available nearly all the time
Up and down
Possibilities
Water heating, w/ smart grid tech
Pumping
Some electrochemical processes
Ice storage for HVAC ? 8

9. Conclusions
Wind integration (i.e. ancillary services) offer a new way for DR to be useful
Not all (maybe not much) DR will qualify
Frequent dispatch
Up and down 9
