Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate optimal plans are created for thermal power generation, hydro power generation, and hot water plans independently, then each individual plan can be optimized, but the overall system optimization is compromised
Solution Approach 1:
The patent merges separate planning processes for thermal power generation, hydro power generation, and hot water supply into a unified planning system. The planning results integration unit combines these previously independent plans into a coordinated overall plan, ensuring system-wide optimization while maintaining the benefits of specialized individual planning.
2Reliability
If hydroelectric power output is increased to meet demand, then power supply reliability improves, but power generation cost increases
Solution Approach 1:
The patent implements dynamic adjustment of hydroelectric power output based on real-time water level conditions and power prices. The hydroelectric power plan adjustment unit continuously modifies the output plan within available water volume constraints, optimizing the balance between meeting power demand and minimizing generation costs through flexible, adaptive planning.
Solution Approach 2:
The system changes key parameters including water level thresholds, power prices, and output levels to optimize the balance between reliability and cost. By adjusting these parameters dynamically based on system conditions, the patent achieves cost-effective power supply while maintaining required reliability levels.
3Device complexity
If multiple planning devices operate independently with separate optimization criteria, then computational simplicity is maintained, but plan coordination and overall optimality deteriorate
Solution Approach 1:
The patent introduces a planning results integration unit as an intermediary component that receives plans from multiple independent planning devices and coordinates them into a unified optimal plan. This intermediary ensures accurate plan coordination while allowing individual planning devices to maintain their computational simplicity and specialized optimization criteria.

AI summary
The economical load distribution adjusting device 10 acquires an optimal hydroelectric output, optimal demand, and optimal power price from the supply-demand planning device 23, acquires the planned hydroelectric output planned by the water level planning devices 21, and acquires a planned demand planned by the hot water tank temperature control devices 22. The economical load distribution adjusting device 10 reduces the power price of the time at which the planned hydroelectric output exceeds the optimal output and makes the water level planning devices 21 replan the hydroelectric output, and raises the power price of the time at which the planned demand exceeds the optimal demand and makes the hot water tank temperature control devices 22 replan the amount of demand.
