An article in Electric Power Systems Research [“On the Self-Scheduling of a Power Producer in Uncertain Trading Environments” (2008, Vol. 78(3), pp. 311–317)] considered a self-scheduling approach for a power producer. In addition to price and forced outages, another uncertainty was due to generation reallocations to manage congestions. Generation reallocation was modeled as 110X −60 (with range [−60,50] MW/h) where X has a beta distribution with parameters α = 3.2 and β = 2.8. Determine the mean and variance of generation reallocation.
