Solution Overview

Problem

Inadequate electricity supply can hinder economic growth in power-intensive sectors, necessitating effective demand side electrical load management to ensure efficient use and prioritization of electricity.

Innovation Solution

A method and system for demand side electrical load management that provides consumers with real-time electricity consumption data, sets consumption thresholds, and interrupts supply if thresholds are exceeded, using a network of remote controllers, master controllers, and computer servers for load balancing and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If electricity supply is increased to meet growing demand, then economic growth is supported, but supply deficiencies and waste occur when demand exceeds supply capacity

Engineering Contradiction:
Improveeconomic growthVSAvoidelectricity waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system implements real-time feedback by continuously monitoring electricity consumption at consumer premises and comparing it against allocated thresholds. The master controller receives consumption data from remote controllers and sends threshold information back to consumers, enabling dynamic adjustment of usage patterns to prevent waste while supporting economic activity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The load management system enables consumers to self-monitor their electricity consumption through displayed threshold information and actively manage their own usage patterns. Consumers receive real-time feedback about their consumption levels and can independently adjust their behavior to stay within allocated thresholds, reducing the need for centralized control interventions.

Inventive Principle:
Principle #25Self-service

2Loss of energy

If load management control is implemented to prevent waste, then electricity efficiency is improved, but consumer convenience and operational flexibility are reduced

Engineering Contradiction:
Improveelectricity efficiencyVSAvoidconsumer convenience
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The system applies partial control by implementing load management thresholds that allow consumers operational flexibility within defined limits. Rather than complete restriction, the system permits consumption up to a threshold level and only intervenes when thresholds are exceeded, maintaining consumer convenience while achieving energy efficiency goals through targeted rather than universal control.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary action by pre-establishing consumption thresholds and providing advance notification to consumers about their allocated limits. The master controller sends threshold information to remote controllers and consumers before consumption issues arise, allowing consumers to plan and adjust their usage patterns proactively rather than experiencing abrupt restrictions.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If real-time monitoring and threshold enforcement are implemented, then electricity distribution efficiency is improved, but system complexity and infrastructure requirements increase

Engineering Contradiction:
Improveelectricity distribution efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the load management function into distributed remote controllers at consumer premises and a centralized master controller. Each remote controller independently monitors local consumption and communicates with the master controller, dividing the complex monitoring task into simpler distributed units that can operate autonomously while contributing to overall system efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The master controller serves as an intermediary between the electricity supply network and consumer premises. It receives consumption data from remote controllers, processes threshold comparisons, and sends control signals back to remote controllers or consumers, mediating the complex interaction between supply management and consumer usage patterns while simplifying the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present disclosure discloses a method (310, 330, 350, 370) of demand side electrical load management and an associated apparatus (104) and system (100). The method (310, 330, 350, 370) includes providing (336, 318) a consumer of electricity with an indication of instantaneous electricity consumption. The method (310, 330, 350, 370) further includes determining (382) an electricity consumption threshold for the consumer, in response to a determination that load limiting is required and providing (384, 356, 338, 320, 322) the consumer with an indication of the electricity consumption threshold and an indication of a time period within which the consumer must limit his/her electricity consumption to comply with the electricity consumption threshold. The method (310, 330, 350, 370) also includes interrupting (360, 340, 342, 324) supply of electricity to the consumer in response to the electricity consumption of the consumer violating the electricity consumption threshold after the time period has elapsed.
