Abstract: A power generation amount prediction apparatus includes a first detector, acquisition unit, database, and controller. The first detector detects a measured value of the power generation amount of a photovoltaic power generation device. The acquisition unit acquires a predicted value of the power generation amount by the photovoltaic power generation device at specific times. The database stores the measured value and the predicted value for each of the specific times for a plurality of days. The controller calculates a corrected predicted value for each of the specific times based on a maximum measured value, a maximum predicted value, and a predicted value newly received by the acquisition unit. The maximum measured value and the maximum predicted value are respectively the maximum value, for each of the specific times, of the measured value and of the predicted value for a predetermined number of days.

Abstract: An energy management apparatus comprises: a receiver configured to receive a first charge information and a second charge information, a memory configured to store information on controlling an operation of an electrical appliance provided in a user's facility, and a processor configured to execute the operation of the electrical appliance based on the information stored in the memory. The processor executes the operation of the electrical appliance based on the second charge information if the second charge information has been received. The processor executes the operation of the electrical appliance based on the first charge information if the second charge information has not been received.

Abstract: A smart controller (102) receives, from an EMS (70), control information as charge information that indicates electricity prices determined in accordance with a power supply of an electric power system (60) and an electric power demand of a consumer group. The smart controller (102) compares the electricity prices with a charge threshold value in a correspondence relationship between a predetermined operation mode and the charge threshold value, thereby determining the operation mode of an illumination (110), an air conditioning device (112), and a heat storage device (114) as loads so as to be an operation mode in which power consumption is reduced as the electricity prices becomes higher, and thus controlling the illumination (110), the air conditioning device (112), and the heat storage device (114) as the load.

Abstract: Provided is a smart controller (102) that detects the amount of power remaining in a storage battery (108). The smart controller (102) also determines the load operation modes of an illumination (110), an air conditioning apparatus (112), and a heat storage apparatus (114) to become modes with lower power consumption when the remaining amount of power becomes lower, by comparing the detected remaining amount of power, and a threshold value in a predetermined correlation between operation modes and threshold values for the remaining amount of power, and thereby controls the illumination (110), the air conditioning apparatus (112), and the heat storage apparatus (114), as loads.

Abstract: A smart controller (102) receives, from an EMS (70), control information in the form of rate information indicating electricity prices determined in accordance both with supply of electricity from a power system (60) and with demand of electricity from a group of users. Additionally, on the basis of comparison of the electricity prices with rate threshold values found in a predetermined correspondence relationship between operation mode and rate threshold value, the smart controller (102) determines an operation mode for a rechargeable battery (108) in such a manner that, as the operation mode, an operation mode in which to discharge electricity is set when the electricity prices is high, and an operation mode in which to charge electricity is set when the electricity prices is low. Furthermore, the smart controller (102) controls the rechargeable battery (108) so that electricity may be charged or discharged in accordance with the thus determined operation mode.
