The Electric Grid
The Grid Control Center
Attributes of Wind Generation • Variability – plant output fluctuates • Uncertainty – output and timing are less predictable than ‘conventional’ generation • Remote locations from network “backbone” • Distributed control systems Electric utilities and control centers take all these factors into account when planning, designing, and operating interconnections with wind generation. 5
New England Wind Resources Significant wind potential with varying characteristics exists throughout New England 1 meter per second roughly 2. 2 mph Legend MWH Class 7 >8. 8 (m/s) Class 6 8 -8. 8 (m/s) Class 5 7. 5 -8 (m/s) Class 4 Source: Levitan Phase II Wind 7 -7. 5 (m/s) Class 3 40 Miles 6. 4 -7 (m/s) Study for ISO New England 230 k.
