Title:
低圧系統の需給計画制御システムおよび低圧系統の需給計画制御方法
Document Type and Number:
Japanese Patent JP5617033
Kind Code:
B2
Abstract:
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.
