Engineering Contradiction Analysis
1Productivity
If a hysteresis band method is used to control renewable energy hydrogen system, then renewable energy self-consumption is improved, but long-term energy utilization and net zero power supply achievement are compromised
Solution Approach 1:
The control apparatus creates predetermined hydrogen storage plans and power supply/demand plans before operation, setting target values for hydrogen storage amount and power exchange. This preliminary planning enables the system to optimize long-term energy utilization and achieve net zero power supply by anticipating future conditions rather than reacting to immediate fluctuations.
Solution Approach 2:
The control apparatus continuously monitors actual operation data including hydrogen storage amount and power supply/demand, compares it with predetermined plan values, and dynamically adjusts control priorities. This feedback mechanism ensures both short-term renewable energy self-consumption and long-term energy utilization goals are achieved by adapting to real-time system state.
2Ease of manufacture
If control is performed based on electricity cost, then economic rationality is improved, but utilization rate of renewable energy is compromised
Solution Approach 1:
The control apparatus dynamically adjusts control priorities among hydrogen production, storage, and power generation based on real-time operation data and predetermined plans. This dynamic control allows the system to optimize both economic rationality and renewable energy utilization rate by adapting to changing conditions rather than following fixed cost-based rules.
3Productivity
If hydrogen production and storage are optimized for immediate use, then short-term energy efficiency is improved, but long-term energy utilization and net zero power supply are compromised
Solution Approach 1:
The control apparatus establishes predetermined hydrogen storage plans that specify target hydrogen storage amounts and timing. This preliminary action ensures that hydrogen production and storage are optimized not only for immediate use but also for long-term energy utilization and net zero power supply achievement by planning ahead.
Solution Approach 2:
The control apparatus monitors actual hydrogen storage amounts and power supply/demand in real-time, comparing them with predetermined plan values. This feedback enables continuous adjustment of control priorities to balance short-term energy efficiency with long-term energy utilization goals.
