On-demand multiple power source management system, on-demand multiple power source management system program and computer-readable recording medium on which said program is recorded

Abstract

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.

Description

technical field [0001] The present invention relates to a storage battery management system for an on-demand power control system in a home or office network, a program for multiple on-demand power management systems, and a computer-readable recording medium on which the program is recorded. According to the quality of life (Quality of Life) (hereinafter referred to as "QoL") required in daily life, the priority among electrical equipment is dynamically changed, so as to control the power consumption (Wh) without exceeding the upper limit value The supply of electric power includes an on-demand multiple power management system that introduces multiple power sources to a commercial power supply without restricting peak power, a program for the on-demand multiple power management system, and a computer-readable recording medium recording the program. Background technique [0002] The on-demand power control system is a system for realizing energy management in homes and office...

Problems solved by technology

However, the current storage battery management is simple management such as schedule management such as charging at night and discharging during the day, and charging when solar power generation is leftover, and there is no effective and adaptive management according to the power usage pattern of each person. Charge and discharge management

In addition, in order to be able to cope with any power usage pattern, there is a tendency to increase the cost of introducing a storage battery with excessive capacity and charging and discharging power.

[0024] In addition, in the case of reducing the peak power consumption of households, etc., only by introducing storage batteries without introducing an on-demand power control system, the capacity of the storage batteries cannot be reduced enough to meet the demand. The degree of peak power

Therefore, in accordance with the increase in the capacity of the storage battery required in this case, the storage battery introduction cost also increases.
