摘要： A supply and demand adjustment system that, when using a plurality of supply and demand adjustment devices and adjusting supply and demand, maximizes the use of the properties of each supply and demand adjustment device and precisely matches total supply and demand adjustment volumes and required adjustment volumes. The supply and demand adjustment system comprises a central control device and at least one supply and demand adjustment device. The central control device comprises: a supply and demand adjustment device status collection unit that collects information relating to the status of each supply and demand adjustment device; an allocation band calculation unit that calculates the frequency band and intensity for supply and demand adjustment fluctuation allocated to the supply and demand adjustment devices, on the basis of the supply and demand adjustment device statuses; and a supply and demand volume calculation unit that calculates the supply and demand adjustment volumes for each supply and demand adjustment device, on the basis of the frequency band and intensity of the supply and demand adjustment fluctuation allocated to the supply and demand adjustment device.

摘要： A time range setting unit (110) sets an operation startable time point at which an operation can be started and a target operation end time point which is the latest time point among time points at which the operation is to be ended, with respect to each of plural power demanding objects (20). A necessary operation time setting unit (120) sets a necessary operation time with respect to each of the plural power demanding objects (20). A shape information acquisition unit (130) acquires shape information from a schedule management device (40). The shape information indicates an assumed shape of a transition line that represents transition in the amount of supplied power in a target period. A demand transition setting unit (140) sets power demand transition information indicating transition in an electric energy demand in the target period so that the necessary operation time is obtained and so that the transition in the electric energy demand generated by the plural power demanding objects (20) being operated accords with the assumed shape.

摘要： An energy management system and an energy management method enable an improvement of the balance between power supply and demand. A storage battery (52) is connected to a power line (42) that transmits outside power. A storage battery controller (54) receives a control signal indicating a reduced use period during which the consumption of the outside power by a consumer apparatus (43) connected to the power line (42) is to be reduced, acquires an index value that has a correlation with the demand for outside power, and on the basis of the control signal and the index value, adjusts the amount of charging/discharging of the storage battery (52).

摘要： A power flow control system is provided that is capable of improving the reliability of controlling power flow fluctuation and creating wide applicability for systems that control power flow fluctuation. A power-varying device (101) varies the distribution line power amount, which is a value of the power flow that flows in a distribution line (112) to which is connected a plurality of power sources (111) that each generate power. A measurement device (102) measures an index value relating to the total generated power amount, which is the sum total of the amount of power generated by each of the power sources. A calculation device (103) estimates the total generated power amount from the index value, and according to the estimation result, regulates the amount of change in the distribution line power amount that is changed by the power-varying device.

摘要： A time point range setting unit (110) sets an operation startable time point when an operation is startable, and an operation end target time point which is a latest time point among time points when the operation is to be ended, with respect to each of plural power-consuming bodies (20). A necessary operation time setting unit (120) sets a necessary operation time with respect to each of the plural power-consuming bodies (20). A shape information obtaining unit (130) obtains shape information from a schedule management apparatus (40). The shape information represents an assumed shape of a transition line indicating transition in the amount of power supplied in a target period. A demand transition setting unit (140) determines power demand transition information indicating transition in electrical energy demand in the target period so that the necessary operation time is obtained and the transition in the electrical energy demand generated by the plural power-consuming bodies (20) being operated follows the assumed shape.
