Solar Power Controller Prioritizing Device Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power supply systems using solar energy face challenges in preventing surplus power generation, leading to instability in grid power when the amount of solar-generated power exceeds consumption, resulting in backflow into the grid.
Innovation Solution
An electric power supply apparatus with a controller that prioritizes and allocates solar-generated power to multiple devices based on predetermined priorities and supply amounts, ensuring that power is used efficiently and minimizing surplus generation by distributing it among devices in descending order of priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If solar-generated power is supplied to the commercial power grid, then electric power can be sold back to the grid, but surplus power occurs and grid power becomes unstable
Solution Approach 1:
The patent applies local quality by prioritizing power supply to specific devices over others based on predetermined priorities. The controller allocates solar-generated power to devices in descending order of priority, ensuring that power is consumed locally before being exported to the grid. This resolves the contradiction by creating a hierarchical power distribution system where critical devices receive power first, preventing surplus power from destabilizing the grid while still allowing excess power to be sold back.
2Loss of energy
If solar-generated power is exported to the grid, then revenue from power selling increases, but surplus power occurs when generation exceeds consumption
Solution Approach 1:
The patent applies preliminary action by pre-establishing priority levels for different devices before power allocation occurs. The controller uses these predetermined priorities to systematically allocate solar-generated power to devices in a specific sequence. This ensures that power is consumed by high-priority devices first, maximizing revenue by minimizing surplus power export, while still allowing controlled power selling when generation exceeds consumption after satisfying all priority-level allocations.
3Productivity
If multiple devices are supplied with solar power simultaneously, then power utilization efficiency increases, but it becomes difficult to stabilize grid power when generation is large
Solution Approach 1:
The patent applies dynamics by implementing a dynamic priority-based power allocation system. The controller continuously monitors solar power generation and device power requirements, dynamically adjusting power distribution according to predetermined priorities. When solar generation is high, the system can supply multiple devices simultaneously in priority order; when generation is low, it dynamically shifts to supply only the highest priority devices. This dynamic allocation maximizes power utilization efficiency while maintaining grid stability by preventing uncontrolled surplus power export.

AI summary
An electric power supply apparatus includes a controller configured to control an amount of generated power, obtained from an energy creation device, supplied to multiple power-using devices capable of being operated or charged with the generated power. The power-using devices are assigned priorities based on an order in which the power-using devices use the generated power, and the controller supplies the generated power to the power-using devices in descending order of the priorities according to the amount of the generated power obtained from the energy creation device and a predetermined supply power amount required by each power-using device.
