Exploiting the Random Nature of Transmission Capacity
SEVERAL YEARS AGO, ENGINEERS AT AMERICAN ELECTRIC Power measured the transfer capability or transmission capacity (in this article we will use the terms interchangeably) between AEP and Commonwealth Edison. Using traditional methods, they found that the winter transmission capacity that year was 3,500 megawatts.
Then they performed a more exhaustive and nonstandard analysis. It showed that during the month of January, transmission capacity actually varied from a low of 1,600 MW (less than half the nominal amount) to a high of 6,000 MW (70 percent higher than nominal).
