<p><P>PROBLEM TO BE SOLVED: To calculate maximum or minimum generation costs of a power plant under a set probability in terms of profit from power trading by an electric company supposed to supply power to fixed consumers. <P>SOLUTION: An energy demand calculation means 12 calculates a probability distribution of total expected energy demand in a set period from total expected energy demand including expected energy demand and set energy in the set period. An integrated power demand calculation means 16 integrates the probability distribution of total expected energy demand in the set period with probability distributions of available power fluctuation in a power plant considering periodic inspection plan changes, unplanned stops and flood fluctuations in the set period, to calculate a probability distribution of integrated power demand in the set period. A generation cost calculation means 16 calculates a probability distribution of unit energy generation costs of the power plant in the set period, and also calculates maximum or minimum unit energy generation costs of the power plant in the set period possible under a set probability. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
