Engineering Contradiction Analysis
1Productivity
If a power control system integrates multiple distributed power sources (photovoltaic cells, storage cells, fuel cells, gas powered generators), then the system can achieve efficient operation control among multiple power sources, but the device complexity increases due to the need to manage and coordinate multiple different power source types
Solution Approach 1:
The patent combines multiple distributed power sources (photovoltaic cells, storage cells, fuel cells, gas powered generators) into a single integrated power control system that manages all power sources through a unified control architecture, enabling coordinated operation while reducing overall system complexity
Solution Approach 2:
The power control system is designed with multi-functional capability to handle different types of power sources simultaneously, providing a universal control mechanism that can adapt to various power source characteristics and operational requirements without requiring separate control systems for each power source type
2Reliability
If the power control system switches between interconnected and independent operations, then the system can ensure seamless power supply during grid-connected and independent operations, but the ease of operation decreases due to the complexity of switching control
Solution Approach 1:
The power control system implements dynamic switching capability that automatically transitions between interconnected and independent operations based on grid conditions and power source availability, eliminating the need for manual intervention and simplifying operational control while ensuring continuous seamless power supply
Solution Approach 2:
The system incorporates feedback mechanisms that monitor grid status and power source conditions in real-time, automatically triggering appropriate switching actions between interconnected and independent modes, thereby maintaining reliable power supply while reducing operational complexity through automated decision-making

AI summary
This system can manage efficient operation control among distributed power sources without impairing their versatility. This power control system includes a power generation device (33) that generates power while a current sensor (40) detects forward power flow and another distributed power source (12), and a power control device (20) including an output unit (50) capable of outputting power from the other distributed power source (12) while the power generation device (33) and the other distributed power source (12) are disconnected from the grid. Output from the output unit (50) allows supply of dummy current to the current sensor (40), the dummy current flowing in the same direction as the forward power flow.
