DEMAND/SUPPLY SCHEDULE CONTROL SYSTEM FOR LOW-VOLTAGE GRID, AND DEMAND/SUPPLY SCHEDULE CONTROL METHOD FOR LOW-VOLTAGE GRID

摘要

The purpose of the present invention is to execute a more minute adjustment of demand/supply of power upon introducing renewable energy. A demand/supply schedule control system (S) for low-voltage grids is composed by comprising: an automatic meter reading system (203) that has stored in a database the estimated amount of power to be used within the low-voltage grids, which is based on track records of the amount of power used by consumers (107) within the low-voltage grids that are managed by power distribution substations (105); a solar/wind-power-generation amount estimation system (205) that has stored in a database the estimated amount of power to be generated by renewable-energy power plants connected within the low-voltage grids; and a battery control system (202) that gives instructions about the amount of power to be charged/discharged into/from rechargeable battery plants (207) connected within the low-voltage grids. The demand/supply schedule control system (S) makes a plan about the amount of power to be charged/discharged into/from the rechargeable battery plants (207), and gives control instructions.
