Solution Overview

Problem

Conventional Building Energy Management Systems (BEMS), Home Energy Management Systems (HEMS), and Factory Energy Management Systems (FEMS) employ centralized integrated control schemes, which fail to account for environmental differences within zones, leading to suboptimal energy management, reduced user convenience, and increased maintenance costs due to inflexibility and the need for frequent system modifications.

Innovation Solution

An Energy Management System (EMS) utilizing a decentralized approach with machine learning algorithms, where community, building, and zone agents independently manage energy based on local data, allowing for plug-and-play functionality, optimal energy cost determination, and user convenience by reflecting current occupied status and energy use patterns, and enabling independent energy management policies for each zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a centralized integrated control scheme is used to manage energy across the entire community, then system-wide coordination is achieved, but the system cannot reflect environmental differences between zones and user tendencies, leading to suboptimal energy management performance

Engineering Contradiction:
Improveability to reflect zone-specific environments and user tendenciesVSAvoidcontrol architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the community into multiple zones, each with its own energy management agent that independently manages local energy resources and demands. This segmentation allows each zone to be optimized according to its specific environmental conditions and user behaviors, while the overall system maintains coordination through standardized communication protocols between agents.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each zone is equipped with localized control capabilities that enable it to adapt to its specific environmental characteristics and user preferences. The local agents can make real-time decisions based on zone-specific data without requiring centralized control, thereby improving adaptability while reducing the complexity of centralized management.

Inventive Principle:
Principle #3Local quality

2Productivity

If a single demand response incentive policy is applied to the entire community, then policy implementation is simplified, but the system cannot achieve high performance across diverse zones with different user tendencies

Engineering Contradiction:
Improveoverall energy management performanceVSAvoidpolicy management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables customization of demand response incentive policies at the zone level, allowing each zone to receive incentives tailored to its specific characteristics and user behaviors. This localized policy approach maximizes the effectiveness of demand response programs while maintaining overall system coordination through standardized agent communication.

Inventive Principle:
Principle #3Local quality

3Productivity

If the system increases compulsion in demand response to achieve higher performance, then energy management efficiency improves, but user convenience is reduced

Engineering Contradiction:
Improvedemand response effectivenessVSAvoiduser convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system incorporates feedback mechanisms that continuously monitor user responses to demand response incentives and adjust the level of compulsion accordingly. By providing real-time feedback on energy consumption patterns and incentive responses, the system can optimize demand response effectiveness while maintaining user convenience through adaptive, rather than purely compulsory, control strategies.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If the centralized system is modified to add new configurations, then the system can handle new devices, but the entire EMS requires modification and recompilation, increasing maintenance costs

Engineering Contradiction:
Improveability to handle new configurationsVSAvoidmaintenance cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system architecture segments the energy management functionality into independent, modular agents that can be deployed and configured separately. This modular structure allows new devices and configurations to be added at the zone level without requiring modification of the entire centralized system, thereby reducing maintenance costs while improving adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The agent-based architecture provides universal interfaces and standardized communication protocols that enable the system to handle diverse device types and configurations through a common framework. This universality allows the system to adapt to new configurations without requiring custom modifications, reducing maintenance complexity and costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

5Productivity

If a single EMS algorithm manages the entire configuration, then centralized control is achieved, but energy supply for each power use pattern cannot be optimized and local load changes cannot be effectively managed

Engineering Contradiction:
Improveenergy supply optimization for each power use patternVSAvoidcontrol algorithm complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control algorithm is segmented into multiple independent agents, each responsible for managing energy supply optimization for specific power use patterns and local load changes within their respective zones. This segmentation allows each agent to specialize in optimizing for its local conditions, improving overall energy supply efficiency while reducing the complexity of any single control algorithm.

Inventive Principle:
Principle #1Segmentation
