Electrical energy is made available incrementally for at least one session (for example for charging an electric vehicle), i.e. to prevent, by way of the delayed provision of the electrical energy, the occurrence of brief severe loading of the energy network. For example, a newly determined load distribution can lead to redistribution of electrical energy for a large number of charging stations, and this redistribution is preferably not carried out at once at a single time for all the affected charging stations but instead is carried out distributed, for example, over multiple points in time. This is advantageous and useful in electric mobility and in load management when charging multiple electric vehicles.

The invention relates to a method for managing the load profile of a low or medium voltage electric network that is supplied by at least an electric power source. The electric network comprises one or more electric loads and one or more controllable switching devices for disconnecting/connecting said electric loads from/with said electric power source. The method comprises the step of measuring a time window from a reference instant, the step of determining at least a check instant comprised in said time window and the step of executing a load profile control procedure at said check instant. In a further aspect, the invention relates to a control system for executing the above described method.

A demand side electric power supply management system is disclosed. The system comprises an islanded power system having a point of coupling to a supply grid. The islanded power system supplies a plurality of electric loads, each of which is associated with a load controller to control the maximum power demanded by that load. A measuring means associated with the point of coupling measures the total power transfer between the grid and the islanded system, and a system controller monitors the measured power transfer relative to a set point and provides a control signal to a plurality of load controllers. Each load controller receives substantially the same control signal and determines the maximum power which the or each load associated with the load controller is allowed to draw from the islanded power system based on information contained in the control signal.

The responsive load control method manages the allocation and adjustment of service triggering grid frequencies across a population of responsive loads. The responsive load control method is particularly suited to responsive loads that have substantially no duty cycle or which have a long duration (>1 hr) duty cycle. With this responsive load control method provision of the responsive load service is shared fairly amongst the population of contributing responsive loads.

A device for performing electric power demand control includes: a processor; and a storage medium including an instruction for causing the processor to obtain a sum of energy consumption of a plurality of manufacturing devices, obtain a production capacity from production information on each manufacturing device, and perform electric power demand control on a manufacturing system based on the production capacity and the sum of energy consumption. To perform electric power control includes determining that electric power demand control is necessary if the sum of energy consumption reaches a predetermined threshold and excluding one of the manufacturing devices having a smallest production capacity from a target of electric power demand control.

A vehicle includes a prime mover, a charging system, a plurality of electrical loads electrically coupled to the charging system, and a controller. The charging system is coupled to the prime mover and includes a charge storing device and an alternator. The alternator is configured to convert mechanical energy generated by prime mover into electrical energy to charge the charge storing device. The electrical loads are electrically coupled to the charging system via a power distribution module. The controller is configured to receive an indication that an electrical output of the charging system is unable to provide sufficient electrical energy to each of the plurality of electrical loads, and provide a control signal to the power distribution module in response to the indication. The control signal is configured to cause the power distribution module to decouple at least one of the plurality of electrical loads from the charging system.

A power management system 1 is provided with an HEMS 500 connected to an SOFC unit 100 and a load 400. The power management system comprises: a reception unit 510 that acquires power consumption of the load; and a transmission unit 520 that notifies the SOFC unit 100 of pseudo power consumption that is obtained by adding a predetermined offset to the power consumption acquired by the a reception unit 510. The SOFC unit 100 controls power output from the SOFC unit 100 to follow the pseudo power consumption.
