Now let's consider the load forecast uncertainty. In System A, the load forecast for the next 2 hours follows a Normal Distribution. The mean of the Normal Distribution is 80MW,

and the standard deviation is 6 MW. What is the expected unit commitment risk for System A in a lead time of 2hours considering the load forecast uncertainty? To calculate the expected unit commitment risk ,please consider 7 possible load scenarios: 62 MW, 68 MW, 74 MW, 80 MW, 86 MW, 92 MW, 98MW.
