<P>PROBLEM TO BE SOLVED: To provide a method and device for preparing the optimum midium and long-term plans for power station demand of a thermal power plant and a pumped-storage power station. <P>SOLUTION: Start and stop variables of the thermal power plant as variables 0, 1 are relieved into real variables, one-day distinctive time points for estimated power demand of midium and long-term power station demand plan issues are extracted, and a start and stop plans are prepared in consideration of LNG consumption restrictions, generator starting frequency restrictions and pumping dam restrictions. Furthermore, based on the prepared plan at an extracted time point, power station demand plans for all-time can be prepared to provide minimum power generation cost in consideration of preset endpoint restrictions. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
