Solar Energy Management Controller for Dynamic Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar energy management systems fail to dynamically adjust energy usage based on solar power generation, leading to inefficiencies and increased reliance on costly conventional power grids during power deficits.
Innovation Solution
A system that determines power status by comparing solar power generation and consumption values, adjusts energy utilization priorities of devices, and controls power consumption by enabling or reducing usage based on surplus or deficit states, using a controller to manage devices and prioritize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system draws power from conventional power lines when solar power is insufficient, then power supply reliability is improved, but energy cost increases
Solution Approach 1:
The system dynamically adjusts power consumption of devices based on real-time solar power availability. When solar power is sufficient, devices operate at full power; when solar power is insufficient, the system selectively reduces power consumption of non-critical devices to avoid drawing from conventional power lines, thus maintaining reliability while minimizing energy costs.
Solution Approach 2:
The system changes operational parameters of connected devices based on solar power conditions. It monitors solar power generation and adjusts device power consumption levels, switching between different operational modes (full power, reduced power, or standby) to optimize the balance between power supply reliability and energy cost.
2Productivity
If the system stores excess solar energy in batteries, then energy utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The system automatically manages its own energy storage and distribution without requiring complex external control. It self-monitors solar power generation, determines when to store excess energy in batteries, and autonomously decides when to discharge batteries to power devices, simplifying the overall system architecture while maintaining high energy utilization efficiency.
3Loss of energy
If the system selectively reduces power consumption of low-priority devices during power deficits, then energy cost is reduced, but device functionality is compromised
Solution Approach 1:
The system applies different power management strategies to different devices based on their priority levels and functionality. Critical devices maintain full power consumption to ensure essential functionality, while non-critical devices have their power consumption selectively reduced. This localized quality approach ensures that energy cost reduction does not compromise essential device functionality.
