Multi-Interval Optimization:<br />

Use of 5-Minute Forecast<br />

• MIO optimizes 5 critical<br />

intervals selected from up to 11<br />

future intervals.<br />

• MIO produces a dispatch<br />

instruction for the next interval<br />

and dispatch advisories for an<br />

additional 4 critical intervals.<br />

• For the dispatch interval, the<br />

variable generators most recent<br />

5-minute forecast is the basis<br />

for determining dispatch<br />

instructions.<br />

• Advisories will use the most<br />

recent 5-minute forecast values<br />

for those intervals<br />
