Engineering Contradiction Analysis
1Reliability
If power production simulation and power distribution simulation are integrated using shared memory and inter-process communication, then simulation fidelity and efficiency are improved, but system complexity increases
Solution Approach 1:
The patent employs shared memory as an intermediary mechanism between the power production simulation system and power distribution simulation system. This shared memory space enables efficient data exchange and synchronization without requiring direct complex inter-process communication protocols, thus improving simulation fidelity while managing system complexity through a standardized intermediate interface.
2Productivity
If PDMSS runs at higher frequency than PPMSS integration time step, then simulation efficiency is improved, but time synchronization difficulty increases
Solution Approach 1:
The patent implements periodic synchronization where the PDMSS runs at a higher frequency but synchronizes its state variables with the PPMSS at regular intervals matching the PPMSS integration time step. This periodic alignment ensures time synchronization accuracy while allowing the PDMSS to operate efficiently at higher frequencies between synchronization points, improving overall simulation efficiency.
3Device complexity
If specialized hardware like reflective memory is avoided, then device complexity is reduced, but data exchange reliability may worsen
Solution Approach 1:
The patent uses software-based shared memory that creates virtual copies of data structures in a common address space accessible by both simulation systems. This copying mechanism eliminates the need for specialized hardware like reflective memory while maintaining data exchange reliability through consistent memory access protocols and synchronization mechanisms implemented in software.
