Power-Supply Control Apparatus Using Predictive Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-supply control systems face issues where executing outdated charge-and-discharge plans can increase peak power consumption or cause new peaks due to differences between current and past power usage statuses.
Innovation Solution
A power-supply control apparatus and method that calculates predictive power consumption values and determines charging/discharging states based on previous plans and additional information, allowing for reliable power supply control even when the latest plans are not delivered, by using a delivery server to generate and distribute charge-and-discharge plans and additional information for storage battery systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a charge-and-discharge plan is stored in memory for later use, then power supply control can be maintained when the latest plan is not delivered, but the plan may become outdated and fail to reflect current power usage patterns
Solution Approach 1:
The system pre-calculates and stores predictive values for multiple future time periods in advance. When the latest charge-and-discharge plan is not delivered, the power-supply control apparatus can refer to these pre-calculated predictive values from previous periods to determine charging/discharging decisions, ensuring continuous reliable operation without needing real-time plan updates.
2Reliability
If a charge-and-discharge plan generated in the past is executed, then power supply control can be maintained, but peak power consumption may increase or new peaks may form due to differences between past and current power usage statuses
Solution Approach 1:
The system dynamically adjusts charging/discharging decisions by comparing predictive values from different time periods. When the latest plan is unavailable, it uses predictive values from previous periods but modifies decisions based on current power usage status detection, ensuring adaptability to changing conditions while maintaining control reliability.
Solution Approach 2:
The power-supply control apparatus detects current power usage status and uses this feedback to adjust charging/discharging decisions when relying on stored predictive values from previous periods. This feedback mechanism prevents execution of outdated plans that would cause peak power consumption increases.
3Reliability
If predictive values are calculated for multiple time periods in advance, then control can be maintained without latest plans, but calculation complexity and processing requirements increase
Solution Approach 1:
The delivery server pre-calculates predictive values for multiple future time periods in advance and delivers them to power-supply control apparatuses. This preliminary action distributes the calculation burden, allowing individual control apparatuses to use these pre-computed values without performing complex real-time calculations when plans are not delivered.

AI summary
A power-supply control apparatus includes a processor that executes a process. The process includes calculating, for a first time period, a first predictive value of total power consumption by the power-supply control apparatus and one or more other power-supply control apparatuses to which power is supplied from a power supply; and determining whether to allow a storage battery to be charged in the first time period based on the first predictive value for the first time period and previous information that is related to the first predictive value and obtained in a second time period before the first time period.
