Operation Plan Creation Device for Methanation Renewable Energy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating operation plans for devices like methanation reactors fail to account for the time required for temperature or pressure raising, leading to non-executable plans when allocating renewable energy, as they do not consider the operational preparation period needed for these devices to switch from a non-producible to a producible state.
Innovation Solution
An operation plan creation device that predicts the amount of renewable energy available and incorporates the operational preparation required time period to determine the optimal start time for production, using a prediction unit and simulation arithmetic unit to calculate the maximum total evaluation quantity and select the best start time for operational preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation plans are created without considering the operational preparation required time period, then the plan creation process is simplified and executed quickly, but the resulting operation plans become non-executable when allocated to devices requiring temperature or pressure raising
Solution Approach 1:
The patent applies preliminary action by incorporating the operational preparation required time period into the operation plan creation process before finalizing the plan. The simulation arithmetic unit calculates this preparation time in advance and uses it to determine the optimal start time for operational preparation, ensuring the device has sufficient time to reach the necessary state (temperature or pressure) before production begins. This resolves the contradiction by maintaining plan creation efficiency while ensuring executability through advance time calculation.
2Reliability
If the operational preparation required time period is incorporated into operation plan creation, then the executability and effectiveness of the plan are improved, but the plan creation process becomes more complex
Solution Approach 1:
The patent applies self-service by designing the simulation arithmetic unit to automatically calculate the operational preparation required time period based on device characteristics and operational parameters. The system determines the optimal start time for operational preparation through internal simulation and evaluation, without requiring manual intervention or complex external calculations. This resolves the contradiction by maintaining reliability through automated time calculation while minimizing process complexity through self-contained system functionality.
3Use of energy by moving object
If renewable energy is allocated without considering the time required for operational preparation, then energy utilization appears optimized on paper, but the actual production is delayed or lost because the device cannot start production at the planned time
Solution Approach 1:
The patent applies feedback by using the simulation arithmetic unit to evaluate the total evaluation quantity based on the relationship between renewable energy allocation and operational preparation timing. The system calculates the optimal start time by considering feedback from the device's preparation requirements and adjusts the operation plan accordingly. This resolves the contradiction by ensuring that renewable energy is allocated in a way that accounts for the device's preparation time, thereby maintaining both energy utilization optimization and actual production output.
