GRID INTEGRATED CONTROL DEVICE, GRID CONTROL SYSTEM, GRID CONTROL DEVICE, PROGRAM, AND CONTROL METHOD

摘要

According to the present invention, at least one grid (3000) distributes power to a consumer (7000). The grid (3000) transmits power to another grid (3000). A grid integrated control device (2000) has: a demanded power amount information acquisition unit (2030) for acquiring, for each grid (3000), the demanded power amount information representing the difference between the amount of power supplied to another grid (3000) and the amount of power supplied from another grid (3000); a cost information acquisition unit (2050) for acquiring cost information representing the cost of power transmission between grids (3000); and a grid controller (2020) for determining, on the basis of the demanded power amount information and the cost information, the amount of power transmitted between the grids (3000) so as to minimize the total power transmission cost while satisfying the power demand for each of the grids (3000).
