A power management server and system that includes a processor to receive and control the operation states of fuel cell systems, prioritizing power generating, starting up, stopping, and stop operating states within a control target period, using specific communication protocols to manage fuel cell systems and distributed power supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fuel cell systems are controlled using existing power management systems designed for storage battery apparatuses, then the systems can be operated, but the control effectiveness and efficiency are insufficient
Solution Approach 1:
The patent changes the control parameters and methodologies specifically for fuel cell systems compared to storage battery apparatuses. The power management server adjusts operational parameters such as starting up time, stopping time, and power output based on fuel cell characteristics, thereby improving control effectiveness while adapting to the specific requirements of fuel cell technology.
2Productivity
If the power management server controls multiple fuel cell systems with different operation states, then comprehensive power supply management is achieved, but the complexity of control increases
Solution Approach 1:
The patent segments the control of fuel cell systems by operation states, categorizing them into four distinct groups: power generating state, starting up state, stopping state, and stop operating state. The power management server applies differentiated control strategies to each segment, managing multiple systems comprehensively while reducing control complexity through structured classification.
Solution Approach 2:
The patent implements dynamic control by adjusting the priority order of fuel cell systems based on their real-time operation states. As systems transition between different states (e.g., from stopping to power generating), their control priorities dynamically change, allowing the power management server to optimize power supply management adaptively without requiring overly complex static control structures.
3Speed
If fuel cell systems are prioritized based on operation states, then rapid power output adjustments are achieved, but the control logic becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-establishing the priority order of fuel cell systems based on their operation states before power output adjustments are needed. The power management server maintains a predefined priority structure (power generating > starting up > stopping > stop operating) that can be rapidly activated without complex real-time calculations, achieving fast power output adjustments with simplified control logic.

AI summary
A power management server controls a fuel cell system including a power generator. The power management server includes at least one processor. The processor is configured to execute a reception process and control process. The reception process incudes a reception process of receiving a massage including an information element indicating an operation state of the fuel cell system. The control process includes a control process of controlling the fuel cell system which the operation state is a power generating state, in preference to the fuel cell system which the operation state is a starting up state, stopping state, and stop operating state, in a control target period.
