Surplus Power Allocation Control for Grid Capacity Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of renewable energy power generation facilities into power grids often leads to overload issues, necessitating output suppression and grid expansion, which increases consumer costs and may leave renewable energy in a standby state until expansion is completed, without specifying when to consume surplus power.
Innovation Solution
A control method that determines whether supply power exceeds grid capacity, and if so, optimally allocates surplus power to distributed computing systems like mining machines and energy storage devices to prevent overload and optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a large number of renewable energy power generation facilities are interconnected to the power grid, then the use of renewable energy is improved, but the power grid becomes overloaded and requires expansion which increases consumer costs
Solution Approach 1:
The patent extracts the surplus power from the power grid system by identifying and separating it from the main power flow. The management device detects when renewable energy generation exceeds grid capacity and extracts this surplus power to supply to computing devices, preventing grid overload while utilizing the renewable energy that would otherwise be wasted.
Solution Approach 2:
The patent introduces a management device as an intermediary between the power grid and computing devices. This intermediary monitors power supply information and grid capacity, makes intelligent decisions about surplus power allocation, and coordinates the distribution of extracted surplus power to computing devices, resolving the contradiction between renewable energy utilization and grid capacity.
2Adaptability or versatility
If the power grid is expanded to accommodate more renewable energy facilities, then the renewable energy interconnection is improved, but the cost borne by consumers increases
Solution Approach 1:
The patent applies preliminary action by proactively monitoring and detecting surplus power before grid overload occurs. The management device continuously acquires power supply information and compares it with grid capacity thresholds, identifying surplus power in advance and allocating it to computing devices before the grid becomes overloaded, thereby avoiding the need for expensive grid expansion.
3Reliability
If surplus power is not consumed, then the power grid remains stable, but the renewable energy is left in a standby condition causing energy waste
Solution Approach 1:
The patent converts the harmful effect of surplus power (which could cause grid overload) into a beneficial outcome by allocating it to computing devices. The management device transforms the potential problem of unused renewable energy into a useful resource for computing operations, simultaneously maintaining grid stability and eliminating energy waste.
Solution Approach 2:
The patent implements a feedback mechanism where the management device continuously monitors power supply information and grid capacity, compares actual power levels with thresholds, and dynamically adjusts surplus power allocation to computing devices. This closed-loop feedback system ensures grid stability is maintained while maximizing renewable energy utilization.
