The present invention relates to a system and configuration for automatically and economically preventing blackout-related disasters caused by power supply and demand mismatches, and more particularly, to an invention in which is disclosed a way of saving a significant fuel cost that is used for maintaining a reserve margin exceeding a certain level to prevent blackouts. The reserve margin monitoring system determines the level of risk of the reserve margin and causes a change from the qualitative physical values of an electrical wave at a basic frequency transferring the level of risk to each consumer - for example, the standard reference values of electrical quality such as voltage, frequency, distortion ratio, and phase shift of the electrical wave - to supply electricity to each consumer. The cabinet panel or individual electrical instrument of a consumer recognizes the level of risk and selectively and gradually controls only electrical loads having low priority by selectively, gradually, and automatically blocking terminal loads having low priorities according to priorities previously assigned to branch circuits below the cabinet panel, and increasing, decreasing, or controlling the load of each electrical instrument, or changing a desired value that is obtained from a control operation performed by the load, so as to automatically avoid a disaster caused by a power supply and demand mismatch, thereby reducing fuel costs by properly lowering a reserve margin that has been excessively maintained. |
