1Productivity
If manual analysis is used for load transfer paths, then analysis can be performed for specific tasks, but it cannot process multiple tasks simultaneously and requires re-analysis for each new task
Solution Approach 1:
The patent pre-calculates and stores risk values for all possible transfer paths between substations before actual load transfer tasks occur. This preliminary computation creates a database of path risks that can be quickly queried and combined for any number of simultaneous transfer tasks, eliminating the need for repeated manual analysis of the same underlying path risks.
Solution Approach 2:
The system creates a universal risk assessment model that can handle multiple different load transfer tasks simultaneously using the same pre-computed fundamental scale matrix. This single system serves all load transfer planning needs across the power grid, rather than requiring separate manual analyses for each specific task.
2Reliability
If traditional methods are used for load transfer control, then simple tasks can be handled, but it is very difficult to simultaneously consider path risk and switch risk
Solution Approach 1:
The patent merges path risk assessment and switch risk assessment into a single unified risk value stored in the fundamental scale matrix. Instead of treating these as separate complex calculations, the system combines both risk factors into one comprehensive metric that can be directly used for comparing different transfer paths, simplifying the decision-making process while maintaining reliability.
Solution Approach 2:
The system transforms complex multi-factor risk assessments into simplified numerical parameters (risk values) that can be directly compared and processed. By converting qualitative risk considerations into quantitative parameters in the fundamental scale matrix, the system makes complex risk trade-offs computationally tractable.
3Measurement precision
If comprehensive risk assessment is performed for all paths, then accurate control parameters can be generated, but computational complexity becomes very high
Solution Approach 1:
The patent performs the computationally intensive risk assessment calculations in advance, before actual load transfer tasks are executed. The fundamental scale matrix is pre-computed containing all necessary risk information, allowing rapid query and combination operations during actual transfer planning without repeating the heavy computational work.
Solution Approach 2:
The system creates a simplified copy or representation of the complex power grid in the form of the fundamental scale matrix. This matrix captures the essential risk characteristics of all possible transfer paths in a compact form that is much easier to process than the full detailed grid model, enabling fast computation while preserving accuracy.
4Reliability
If power flow reverse examination is performed thoroughly, then transfer safety can be ensured, but it becomes a very difficult task
Solution Approach 1:
The patent performs power flow reverse examination as part of the preliminary computation when building the fundamental scale matrix. By detecting and marking paths with reverse power flow issues in advance, the system eliminates the need for repeated complex examinations during actual transfer tasks, reducing both difficulty and computational burden.
