Smart Grid Energy Distribution via Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart grid systems lack an efficient method for distributing energy, leading to frequent blackouts due to peak energy consumption and inefficient resource usage, which increases costs and reduces operational efficiency.
Innovation Solution
A smart grid system that categorizes devices into non-shiftable, controllable, and shiftable types, using price data and historical resource information to distribute resources based on priority, fairness, and cost considerations, optimizing resource allocation and consumption strategies to minimize peak usage and maximize efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy resources are distributed to all devices at all stages, then device operational requirements are met, but resource consumption costs increase and blackouts occur during peak demand
Solution Approach 1:
The patent segments devices into three categories (non-shiftable, controllable, and shiftable) based on their energy consumption characteristics and requirements. This segmentation allows the system to apply different distribution strategies to different device types, ensuring critical devices receive adequate resources while non-critical devices have their consumption managed during peak periods, thus resolving the contradiction between meeting operational requirements and controlling energy costs
Solution Approach 2:
The system performs preliminary classification of devices into different types before the actual energy distribution process. By pre-identifying which devices are non-shiftable (must be supplied), controllable (can be adjusted), and shiftable (can be delayed), the system prepares an optimized distribution plan in advance that prevents blackouts while controlling costs, rather than reacting to peak demand situations
2Productivity
If energy resources are distributed uniformly to all devices, then distribution simplicity is maintained, but resource usage efficiency decreases
Solution Approach 1:
The patent divides the device population into distinct segments (non-shiftable, controllable, shiftable) with different energy distribution rules. This segmentation enables the system to optimize resource allocation by directing more resources to high-priority devices and limiting or delaying resources for lower-priority devices, thereby improving overall resource usage efficiency without requiring complex real-time adjustments
Solution Approach 2:
The system changes the distribution parameters (amount of energy, timing of delivery) based on device type classification. By adjusting these parameters according to pre-defined device categories rather than treating all devices uniformly, the system achieves efficient resource allocation through relatively simple parameter-based differentiation rather than complex individualized control
3Ease of operation
If peak energy consumption is allowed, then user convenience is maintained, but blackouts occur frequently
Solution Approach 1:
The patent implements dynamic energy distribution that adapts to different device types and demand conditions. Non-shiftable devices maintain their operational convenience regardless of conditions, while controllable and shiftable devices have their energy delivery dynamically adjusted based on grid conditions. This dynamic approach preserves user convenience for critical devices while preventing blackouts through flexible management of non-critical devices
Solution Approach 2:
The system applies different quality levels of service to different device types: non-shiftable devices receive guaranteed energy supply with high reliability, controllable devices receive adjusted supply based on conditions, and shiftable devices receive delayed or reduced supply during peak periods. This local differentiation of service quality maintains convenience for essential devices while ensuring grid stability through reduced demand from non-essential devices during critical periods
