HYDROELECTRIC POWER GENERATION PLAN ADJUSTING DEVICE, HYDROELECTRIC POWER GENERATION PLAN ADJUSTING METHOD AND PROGRAM

摘要

The economical load distribution adjusting device 10 acquires an optimal hydroelectric output, optimal demand, and unit power generation cost from the supply-demand planning device 23, acquires the planned hydroelectric output planned by the water level planning devices 21 by providing a price signal created by converting the unit power generation cost, and acquires a planned demand planned by the charge control devices 22 by similarly providing a price signal. The economical load distribution adjusting device 10 adjusts the power price of the time at which the planned hydroelectric output does not agree with the optimal output and makes the water level planning devices 21 replan the hydroelectric output by providing a price signal obtained by converting the adjusted power price, and adjusts the power price of the time at which the planned demand does not agree with the optimal demand and makes the charge control devices 22 replan the amount of demand by providing a price signal obtained by converting the adjusted power price.

主权项

1. A device for adjusting a plan of hydroelectric power generation, communicatively connected to a supply-demand planning device and each of a plurality of hydroelectric power generation planning devices, the supply-demand planning device calculating an optimal value of an output per a unit time by the hydroelectric power generation as well as calculating an optimal value of a power price per the unit time, and the each of the plurality of the hydroelectric power generation planning devices planning the output by the hydroelectric power generation in accordance with the power price, the hydroelectric power generation plan adjusting device comprising:
an optimal supply-demand plan acquiring unit configured to acquire from the supply-demand planning device the optimal value of the output per the unit time and the optimal value of the power price; a price signal creation unit configured to create a price signal that is a value obtained by converting the optimal value of the power price using a predetermined algorithm; a power generation planning device control unit that controls the hydroelectric power generation planning devices to plan the output in accordance with the price signal and acquires planned values of the output from the hydroelectric power generation planning devices; and a price adjusting unit configured to increase or reduce the power price for the unit period in which a difference between a total value of the planned values of the output and the optimal value of the output is equal to or greater than a predetermined output difference threshold value, wherein the price signal creation unit creates the price signal by converting the increased or reduced power price, and the power generation planning device control unit re-controls the hydroelectric power generation planning devices to plan the output in accordance with the created price signal.
