 Optimization calculating part, calculates by optimization to calculate the most suitable supply and demand of energy utilization and use cost and energy utilizationFit and supply requirement；
Forecast error presumption unit, using the actual achievement value of the supply demand error of the energy utilization in the past comprising current time, comesThe presumed value of the supply demand error of the energy utilization calculating future；
With cost increase amount calculating section, calculate the supply demand mistake with the energy utilization being calculated by described forecast error presumption unitThe ascending amount of cost is used in the supply and demand of the corresponding energy utilization of presumed value of difference；
With cost error correction portion, calculate and add by described utilization in the supply and demand being calculated by described optimization calculating part is with costThe supply and demand that cost increase amount calculating section calculates uses the value obtained from ascending amount of cost as with cost error correction value；
AndAlarm output section, has following function：
Carry out present situation in the supply and demand being calculated by described optimization calculating part with cost ratioTrend operation when energy utilization supply and demand use the actual achievement value of cost low in the case of, and in described utilization cost error correction valueThe supply and demand of energy utilization when operating than the trend carrying out present situation uses the high situation of the actual achievement value of cost or by described fortuneIn the case of being more than setting value with the supply and demand that cost increase amount calculating section calculates with the ascending amount of cost, export alarm signalBreath；
The actual achievement value of confession requirement of energy utilization of output current time and the energy utilization being calculated by described optimization calculating partThe most suitable confession requirement.

Abstract
This energy supply and demand operational guidance device comprises an alarm display unit (7) which displays alarm information on a guidance screen (8) if the operating cost calculated value is lower than the operating cost actual value and if the operating cost corrected value is higher than the operating cost actual value or the amount of increase in the supply and demand operating cost calculated by an operating cost increase calculation unit (4) is greater than or equal to a set value. Further, the alarm display unit (7) outputs the actual value of the supply and demand amount of an energy utility at the present time and an optimal supply and demand amount of the energy utility calculated by an optimization calculation unit (5). By this means, it is possible to suppress increases in the operating cost of an energy utility which are due to prediction errors in the future supplydemand balance of the energy utility.
