Power consumption optimization device

Abstract

The purpose of the present invention is to provide a power consumption optimization system which performs control for optimizing electric energy fees.　A HEMS controller 100, which is a power consumption optimization device for controlling a household power source system equipped with a storage battery, comprises: an acquisition unit (basic fee acquisition unit 104a, etc.) for acquiring fee system information about commercial power 20; a setting unit 103 which functions as an acquisition unit for acquiring setting information about a storage battery 100e, an apparatus 110a, or the like; and a control unit 104 which controls the charge / discharge of the storage battery 110e and the operation of the apparatus 110a (eco cute, air conditioner, or the like) on the basis of the fee system information, the setting information, and external factor information (temperature, resource use history).

Claims

[Claim 1] In a power consumption optimization device that optimizes power consumption for a controlled object, An acquisition unit that acquires pricing information for commercial electricity, which includes at least variable electricity rates where the unit price fluctuates depending on the time of day, and a basic charge determined based on the maximum instantaneous power consumption. The acquisition unit acquires setting information for the control target, which includes at least an operational constraint that once operation has started, operation cannot be interrupted for a predetermined period of time. An external factor information acquisition unit acquires external factor information that affects the power consumption of the controlled object, A control unit controls the target to minimize the total electricity charge, taking into account the variable electricity charge and the basic charge, based on the external factor information, the rate system information, and the setting information. A power consumption optimization device equipped with the following features. [Claim 2] The aforementioned external factor information is resource usage history information used by the controlled object in its operation. The power consumption optimization device according to claim 1. [Claim 3] The aforementioned external factor information is environmental information in which the controlled object operates. The power consumption optimization device according to claim 1. [Claim 4] The setting information further includes the target value on which the controlled object operates. The power consumption optimization device according to claim 1. [Claim 5] The aforementioned pricing information includes at least a basic charge indicating the minimum usage charge structure for electricity, and further includes at least one of an incentive price and a variable electricity rate. The power consumption optimization device according to claim 1. [Claim 6] The control unit, Using an electricity rate function, the operation of the controlled object is determined for each controlled object and each controlled object time. The power consumption optimization device according to claim 1.
