In order to provide an electric power system in which a plurality of electric power suppliers and demanders are configured by being mutually connected via electric power supply and demand control devices, the electric power system being not only self-sustainable without depending on a known electric power system, but also capable of coexisting with the known electric power system. The electric power system is such configured that a plurality of electric power suppliers and demanders 11 to 15 are mutually connected via an electric power supply and demand line W, the electric power supplier and demander being provided with power generation devices 101 and 151, electrical storage devices 102 and 152, a plurality of loads 103, and electric power supply and demand control devices 104 and 153. The electric power supply and demand control device 104 determines whether or not electric power shortage is occurred or whether or not electric power surplus is occurred in the electric power supplier and demander 11 provided with the electric power supply and demand control device 104, receives electric power from other electric power suppliers and demanders 12 to 15 provided with the power generation device and/or the electrical storage device in the case where electric power shortage is occurred in the electric power supplier and demander 11, controls to deliver electric power to other electric power suppliers and demanders 12 to 15 in the case where electric power surplus is occurred in the electric power supplier and demander 11, and automatically or manually controls the plurality of the power generation devices including a co-gene in respective power suppliers and demanders 11 to 15 on the basis of weather forecast, electric power demand prediction, heat demand prediction, setting values by each supplier and demander, and the like in the delivery and receipt of electric power. |
