Solution Overview
Problem
The electricity grid's operation frequency fluctuates outside safe bands due to changes in power supply and load, potentially damaging generators and consumer equipment, necessitating a real-time adjustment system to maintain safe frequency ranges.
Innovation Solution
An electric load network comprising interconnected computing devices, a site server, and a frequency reader that adjusts the collective operation power of the devices to stabilize the grid's frequency by reducing or increasing power consumption based on frequency deviations, with the site server determining necessary power changes and instructing devices to adjust their chipset power accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operation frequency of the electricity grid fluctuates outside safe bands due to changes in power supply and load, then the electricity system can respond to changes in power demand and supply, but generators and consumer equipment may be damaged
Solution Approach 1:
The patent implements a feedback mechanism where the frequency reader continuously monitors the operation frequency of the electricity grid and reports it to the site server. The site server compares the measured frequency with the reference frequency and automatically adjusts the power consumption of computing devices based on the frequency deviation, creating a closed-loop control system that responds to frequency fluctuations in real-time
Solution Approach 2:
The computing devices automatically adjust their own power consumption based on instructions from the site server. Each computing device monitors its own operation state and modifies its chipset power consumption to contribute to stabilizing the grid frequency, enabling the load side to actively participate in frequency regulation without manual intervention
2Reliability
If the collective operation power of computing devices is changed to stabilize grid frequency, then the operation frequency can be maintained within safe limits, but the productivity of computing tasks may be reduced
Solution Approach 1:
The patent dynamically adjusts the power consumption of computing devices based on real-time grid frequency conditions. The site server calculates the required power adjustment based on frequency deviation and instructs computing devices to modify their chipset power accordingly, allowing the system to adapt power consumption to grid conditions while maintaining computing functionality
Solution Approach 2:
The patent changes the operational parameters of computing devices by adjusting chipset power consumption levels. The site server determines the required power change and instructs computing devices to operate at modified power levels, thereby using parameter adjustment as a control mechanism to balance grid stability and computing productivity
3Reliability
If the site server continuously monitors and adjusts power consumption to maintain frequency stability, then safe operation is ensured, but the system complexity increases
Solution Approach 1:
The site server performs multiple functions: it receives frequency data from the frequency reader, calculates frequency deviations, determines required power adjustments, and sends control instructions to computing devices. This multi-functional approach consolidates control logic in a single component, managing system complexity through functional integration
Solution Approach 2:
The site server acts as an intermediary between the frequency reader and computing devices. It receives frequency information from the frequency reader, processes the data to determine appropriate power adjustments, and transmits control instructions to computing devices, simplifying the control architecture by introducing a dedicated coordination layer
