    摘要: There is provided an electricity demand regulating system which estimates a load amount of an individual equipment whose measurement information can not be acquired and improves estimation accuracy of an electricity demand amount in a power system. The electricity demand regulating system for managing electric energy used by a consumer according to an operation state of the power system includes a storage part to store measurement information of a consumer equipment, and a generation part to generate a load pattern indicating a load amount tendency from the measurement information of the equipment stored in the storage part. A load amount of an equipment whose measurement information is not stored in the storage part is estimated from the load pattern generated by the generation part, and an electricity demand amount of the consumer is obtained based on the measurement information and the estimated load amount.

    摘要: A battery control apparatus includes a reduced electricity cost analysis unit that obtains a discharge electric power cost at a discharge time and a charge electric power cost at a charge time of a battery, based on a basic cost and a unit cost of an electricity bill, and obtains a reduced electricity cost in which the charge electric power cost is subtracted from the discharge electric power cost for every discharge depth of the battery; an introduction cost analysis unit that calculates an introduction cost of the battery for every discharge depth of the battery; and a charge and discharge depth optimization unit that obtains a difference of the reduced electricity cost and the introduction cost for every discharge depth of the battery, and determines a charge and discharge depth of the battery based on the difference. The discharge of the battery is performed at the determined charge and discharge depth.

    摘要: Example implementations described herein involve a hybrid spatial-temporal event probability prediction method and system configured to predict spatial-temporal event probability that can be utilized for short term planning. For systems such as utility systems that manage multiple locations over time, the example implementations utilize both a spatial model and a temporal model to create a hybrid spatial-temporal model that accounts for data taken over time as well as data across the locations to more accurately forecast the probability of an event occurrence over a period of time.

    摘要: A power demand regulation system has a power demand regulation device that regulates the load applied to equipment of an electrical power system by a load apparatus operating by means of power from the electrical power system, which supplies power to consumers. When regulating the load to the equipment, the power demand regulation device selects a load apparatus as the subject of a request for an alteration of operating state on the basis of by-apparatus load information, which is information of each load apparatus, and a regulation target value, which is the amount of load that is to be regulated, and, in the period from the start to the end of regulation, executes a plurality of times the outputting of an alteration request that requests the alteration of the operating state of the selected load apparatus.
