An operator expects the system load to be constant for the next few hours at 360 MW. a) How many identical 60 MW thermal units must he commit and spin if the failure rate of each is 5 f/yr, the lead time is 2 hours and the unit commitment risk must be less than 0.005? b) How should these units be dispatched in order to minimize the 5 minutes response risk if the response rate of each is linear at 1 MW/minute? c) Evaluate the response risk if the system requires a minimum of 35 MW to respond within 5 minutes.
