Solution Overview

Problem

Existing power control systems fail to adjust control for individual consumer equipment based on specific operation conditions, leading to inefficiencies in managing power usage within groups of consumers.

Innovation Solution

A power control system that includes prediction units to forecast power usage, set limit values, and control units to manage power usage per consumer equipment, ensuring the total power usage does not exceed targets, while adjusting to real-time operating conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a DS plan is created before execution, then the control can be established in advance, but the control cannot be adjusted during execution based on specific operation conditions of individual consumer equipment

Engineering Contradiction:
Improveadaptability to operation conditionsVSAvoidcontrol adjustment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustment of control parameters during execution by introducing a determination unit that calculates adjustment amounts based on actual operation conditions. The control amount for each consumer equipment is dynamically modified within a time period based on determination values, allowing the system to adapt to changing conditions while maintaining overall control structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback mechanism where the determination unit continuously monitors operation conditions of consumer equipment and adjusts control amounts accordingly. The adjustment amount is determined based on feedback from actual power consumption data and operation status, enabling real-time optimization without complete re-planning.

Inventive Principle:
Principle #23Feedback

2Productivity

If control is adjusted for each individual consumer equipment based on specific operation conditions, then the power usage can be optimized, but the control system complexity increases

Engineering Contradiction:
Improvepower usage efficiencyVSAvoidindividual equipment control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the control system into independent controllable units, where each consumer equipment can be individually adjusted based on its specific operation conditions. The determination unit processes each equipment separately, calculating adjustment amounts based on individual power consumption patterns and operational status, enabling targeted optimization without affecting the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial adjustment rather than complete re-control of each equipment. The determination unit calculates adjustment amounts that are applied within existing control frameworks, making incremental modifications to power consumption based on operation conditions rather than implementing entirely new control strategies for each device.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

[Object] To control power usage by a group including a plurality of consumers by performing additional adjustment according to a specific operation condition of each individual piece of consumer equipment and appropriately controlling power usage per piece of consumer equipment. [Solution] A system for performing power control such that a target power set for a group including a plurality of consumers is not exceeded includes a first prediction unit 320 that performs prediction on power usage of each consumer included in the group over each of time periods; a limit value setting unit 330 that sets limit values, based on a prediction result obtained by the first prediction unit 320 such that a total value of power usage of the consumers does not exceed the target power for each of the time periods; a second prediction unit 350 that predicts, within a current time period, power usage of the consumers over this time period; and a limit value adjustment unit 370 and a control information generation unit 340 that control the power usage of the equipment devices of each consumer, based on predicted values of the power usage of the consumers over the current time period, the predicted values being obtained by the second prediction unit 350.
