Hydroelectric power generation plan adjustment device, hydroelectric power generation plan adjustment method, and program

摘要

The economical load distribution adjusting device 10 acquires an optimal hydroelectric output, optimal demand, and optimal power price from the supply-demand planning device 23, acquires the planned hydroelectric output planned by the water level planning devices 21, and acquires a planned demand planned by the hot water tank temperature control devices 22. The economical load distribution adjusting device 10 reduces the power price of the time at which the planned hydroelectric output exceeds the optimal output and makes the water level planning devices 21 replan the hydroelectric output, and raises the power price of the time at which the planned demand exceeds the optimal demand and makes the hot water tank temperature control devices 22 replan the amount of demand.

1. A hydroelectric power plan adjusting device for adjusting a plan of the hydroelectric power, communicatively connected to each of a supply-demand planning device, and a plurality of hydroelectric power planning devices, the supply-demand planning device calculating an optimal value of output per unit time by hydroelectric power generation and an optimal value of electric power demand per unit time of an electrical equipment as well as calculating a first power price which is an optimal value of power price per the unit time, and each of the hydroelectric power planning devices planning an output by the hydroelectric power generation in accordance with a given power price, the device comprising:
an optimal supply-demand plan acquiring unit configured to acquire from the supply-demand planning device an optimal value of the output and the first power price per the unit time; an optimal output acquiring unit configured to control each of the plurality of hydroelectric power planning devices to calculate a planned value of the output according to the first power price and acquire the planned value of the output from each of the hydroelectric power planning devices; a price adjusting unit configured to generate a second power price updated by reducing the first power price for the unit time based on a determination that the total amount of the planned values of the outputs exceeds the optimal value of the output for the unit time and controls at least one of the plurality of hydroelectric power planning devices so that a planned value of an output is recalculated according to the generated second power price; and a unit configured to adjust the amount of the water intake to at least one reservoir in at least one hydroelectric power station in accordance with the recalculated planned value of the output.
