PROBLEM TO BE SOLVED: To provide an energy management system that uses IEC 61850 to enable seamless connection and can directly control a user side facility through a regional energy management system in the case that a predetermined condition is satisfied.SOLUTION: An energy management system includes a CEMS 1, BEMS 2, controller IED 3, and access management module 3A for determining whether to permit control commands from a user facility 4 and the CEMS 1 that are made to be capable of performing seamless mutual communication using IEC 61850. The access management module 3A, when predetermined registration is already completed for a connection establishment request transmitted from the CEMS 1, permits connection and controls an electric facility according to a control command transmitted by the CEMS 1 itself under a condition that LLN0.LocSta.stVal of an IEC 61850 server application 3B is in a False mode or only monitors the user facility 4 under a condition that the LLN0.LocSta.stVal of the IEC 61850 server application 3B is in a True mode.SELECTED DRAWING: Figure 1 |
