Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed power generation systems face inefficiencies in energy recovery due to varying power generation methods, which can lead to decreased energy recovery efficiency when performing load-following operations.
Innovation Solution
A power generation system with multiple apparatuses, where one is designated as a master and others as slaves, dynamically adjusts priorities and power generation outputs based on load consumption, ensuring efficient energy recovery by optimizing power distribution and reducing unequal degradation among components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If load-following operation is performed to match power generation output with load consumption, then energy recovery efficiency is improved, but unequal degradation of power generation apparatuses occurs
Solution Approach 1:
The patent implements dynamic control of power generation output by switching between rated operation and load-following operation modes. The master apparatus dynamically adjusts the operation mode of slave apparatuses based on real-time load consumption levels, enabling the system to adapt to varying energy demands while managing degradation patterns through controlled operational dynamics
2Productivity
If rated operation is performed to maximize power generation output, then productivity is improved, but energy recovery efficiency decreases when load consumption is low
Solution Approach 1:
The system dynamically switches between rated operation and load-following operation based on load consumption thresholds. When load consumption is high, apparatuses operate at rated output to maximize productivity. When load consumption drops below the threshold, the system transitions to load-following mode to match output with demand, thereby maintaining high energy recovery efficiency while preserving productivity when needed
Solution Approach 2:
The control system changes operational parameters by adjusting power generation output levels based on load consumption conditions. The master apparatus monitors load consumption and modifies the operating parameters of slave apparatuses, switching between full rated output and reduced load-following output to optimize the balance between productivity and energy recovery efficiency

AI summary
A power generation system including a plurality of power generation apparatuses and configured to supply electric power to a load by performing interconnecting operation of the plurality of power generation apparatuses sets one of the plurality of apparatuses as a master apparatus and the other power generation apparatus as a slave apparatus. When power consumption by the load is less than electric power generated by rated operation of the master apparatus and the slave apparatus, the master apparatus causes the master apparatus and the slave apparatus to generate power in such a manner that the electric power supplied to the load follows the power consumption by the load.
