Abstract: In a power interchange system, a power generated by a power generation device is interchanged between power consumers which receive an electric power supply from a power supply system. The amount of electric power sold by a power consumer is defined as an amount of selling power, and the amount of electric power that the power consumer demands from another electricity consumer is defined as an amount of purchasing power. Power interchange groups are formed, in which power consumers interchanges an electric power thereamong, and each power consumer is provided with a power control device which manages the electric power from the power generation device.

Abstract: An environmental apparatus control system for a comfortable residential environment based upon demands from the residents. The system includes a project composer which relies upon a first reference (R1) and a second reference (R2) to determine a control project based upon the demands. The references are each determined by a first proportion of the count of the temperature lowering demands in the total number of the residents, and a second proportion of the count of the temperature raising demands in the total number of the resident. A first proportion of the count of the first demands in the number of the residents, and a second proportion of the count of the second demands in the number of the residents are obtained to give a current demand ratio which is compared with first and second references for determination of the control project. The first and second references and are defined respectively as different ratios of the first proportion to the second proportion.

Abstract: The energy management system includes a judging means (103), a usage information means (105), a schedule input means (106), a simulating means (108), a prediction information indicating means (110). The judging means (103) judges whether or not the device was used for each unit time, on the basis of power consumption of the device in a predetermined time period (measurement value). The usage information indicating means (105) indicates whether or not the device was used for each unit time, on the basis of the judgment result of the judging means (103). The schedule input means (106) requires a user to input schedule information which defines operation of the device for each unit time in the predetermined time period. The simulating means (108) calculates power consumption (prediction value) used in the device which operates in accordance with the schedule information input via the schedule input means (106), on the basis of the measurement value.

Abstract: An environmental apparatus control system assures a consistent temperature control for realizing a comfortable residential environment based upon demands from the residents, yet in an energy-saving manner. The system includes an apparatus for controlling a residential space, and an initializer which provides an initial target value for control of the residential space at the start of operating the system. Comfortableness demands from residents are analyzed in order modify the initial target value to a working target value. The initial target value is shifted in a direction of saving the energy such that the working target value can always approach from and settle on the energy-saving side as the demands from the residents are analyzed. The working target values within a past time period are weighted to give a corrected target value which replaces the initial target value for the start of next operation cycle of the system.
