The purpose of the present invention is to be able to control the supply of power of a commercial power source in real time in relation to the power request needed by a user and to control the supply of power matching the QoL the user needs in daily life. The dynamic priority control device of the present invention is characterized by being provided with an initial target value updating means and a power arbitration means. The initial target value updating means calculates an updated initial target value by distributing the difference between the instantaneous power of the initial target value and the actual instantaneous power to the instantaneous power of the subsequent initial target value, and compares said updated initial target value with a maximum target value. If the aforementioned updated initial target value is smaller than the maximum instantaneous power, the initial target value updating means updates the instantaneous power of the subsequent target value as the updated initial target value. Meanwhile, if the updated initial target value is greater than the maximum instantaneous power, the initial target value updating means updates the instantaneous power of the initial target value to the maximum instantaneous power and sets said value as the updated initial target value. The power arbitration means calculates the total value of the consumption power of electronic devices in operation, calculates the priority of both electronic devices on the basis of a set of electronic device characteristic class data, and compares the consumption power total value with the updated initial target value. If the consumption power total value is smaller than the updated initial target value, the power arbitration means supplies power to the transmitted electronic devices. Meanwhile, if the consumption power total value is greater than the updated initial target value, the power arbitration means selects an electronic device having the lowest priority by calling the priorities from the memory, determines the nature of the feature of the electronic device by referring to the abovementioned class data, and performs arbitration on the basis of the priorities among the electronic devices.

The invention provides an image forming apparatus and a control method thereof. The image forming apparatus is capable of appropriately controlling power supplies to respective parts thereof when the apparatus is remotely started over a network. When receiving data from an external apparatus via the network, a controller of the image forming apparatus decides power supplied object, among a plurality of power supplied objects of the image forming apparatus, to which power supply is to be started at startup of the apparatus, and controls such that power supply to the decided power supplied object is started.

An object of the present invention is to provide an on-demand control system that supplies power to electric devices based on not predetermined priorities fixed to electric devices, but based on priorities changed according to the use status of the user. The on-demand control system can control supply of power of a commercial power source in real time in response to a power request necessary for the user and controls the supply of power according to the QoL necessary for the user through daily life. The on-demand power control system of the present invention is a multiple power source management system for an on-demand power control system, the on-demand power control system including: a plurality of power sources; a plurality of electric devices; smart taps connected to the electric devices; a multiple power source management apparatus that includes a memory and that controls supply of power to the electric devices; and a network for the multiple power source management apparatus connected through the smart taps, wherein the multiple power source management apparatus includes: power supply plan generation means for setting a power use plan of a commercial power source as initial values of a supply plan of a capacitor, searching a time zone with a maximum dissatisfaction among the time zones of the initial values to set the time zone as a time-shift destination, searching a time zone with a minimum dissatisfaction to set the time zone as a time-shift source, and repeating the process until the dissatisfaction of the time-shift destination is smaller than the dissatisfaction of the time-shift source to generate a power supply plan; supply power target value update means for setting a target value of supply power for each of the plurality of power sources and feeding back and updating an error between actual power supply amount and the supply power target value at each minimum control interval; and power and power source arbitration means for repeating a process of selecting a device with a minimum priority among an electric device that has requested power and electric devices in operation, selecting a power source with a maximum power source load factor, reducing or stopping power of the electric device, and reducing supply power of the power source by an amount of the reduced power until the following Expressions (1) and (2) are satisfied, thereby arbitrating the power and the power sources to satisfy Expressions (1) and (2) at the same time.

The invention discloses a photovoltaic power station active power output control system and method, comprising the following steps: 1) calculating the active power sensitivity and the sum of the sensitivity at the grid connection points of each photovoltaic power generation unit in the photovoltaic system; 2) determining a P(U) strategy algorithm according to the sensitivity , obtain the grid-connected point voltage U and output the load demand power P* of the photovoltaic power station through the P(U) strategy algorithm; 3) The photovoltaic power station load demand power P* and the photovoltaic power generation unit Ppvmax are processed by the subtractor to determine whether the electric energy storage device is input and output active power ; 4) Determine the time when different electric energy storage devices are put into the system according to the time when the load requires power; 5) According to the determined number of photovoltaic power generation units put into the photovoltaic power station and the time when the electric energy storage device is put into the system, control the photovoltaic power plant to output active power. The invention can safely and efficiently control the output of the photovoltaic power station.

The aerosol generating system comprises: a housing (12) having an air inlet (14) and an air outlet (16) defining an airflow channel (18); a heater element (24); and a cartridge (10) which can is movably mounted in said housing (12) and reversibly movable from a first position to a second position. The cartridge (10) comprises a liquid storage portion (18) for containing an aerosol-generating liquid and has an opening for delivering said aerosol-generating liquid, said cartridge further comprising a movable piston (28). When an air flow is generated between the air inlet (14) and the air outlet (16), the air flow within the housing (12) moves the cartridge (10), and the cartridge (10 ) triggers the release of a portion of the aerosol-generating liquid through the opening of the cartridge (10).
