Power Consumption Control with Capacity-Based Load Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power consumption systems lack active control mechanisms, leading to passive protection methods that cause grid fluctuations and potential damage, especially in microgrid operations, due to the lack of interaction between power supply and consumption systems.
Innovation Solution
An energy control method and apparatus that communicatively connects power supply and consumption systems, allowing for active management by determining the power supply capacity and prioritizing device startup or shutdown to ensure stable operation, using a signal receiving module, state information acquisition, determining module, signal sending module, and electric energy output control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive protection methods (switching off power, tripping upon overcurrent) are used, then grid protection is achieved, but grid stability deteriorates due to fluctuations and shocks
Solution Approach 1:
The energy control apparatus performs preliminary assessment of power supply capacity before allowing power consumption devices to start up. It determines whether the power supply system can meet the starting power requirement in advance, preventing situations that would lead to passive protection triggers and maintaining grid stability proactively
Solution Approach 2:
The system establishes bidirectional communication between power supply system and power consumption devices through the energy control apparatus. Real-time feedback on power supply capacity and consumption status enables dynamic adjustment of power allocation, replacing passive reaction with active control that maintains both protection and stability
2Stability of the object's composition
If active control is implemented to maintain grid stability, then grid stability improves, but system complexity increases due to communication and control mechanisms
Solution Approach 1:
The energy control apparatus serves as an intermediary between the power supply system and power consumption devices. It centralizes the communication and control functions, managing power capacity assessment and device coordination without requiring complex direct interactions between all system components, thus controlling overall system complexity
3Speed
If power is allocated without prior assessment, then device startup speed improves, but power supply safety deteriorates due to capacity mismatches
Solution Approach 1:
The system performs preliminary determination of power supply capacity before device startup. The energy control apparatus assesses whether the power supply system can meet the starting power requirement in advance, ensuring safety conditions are met before enabling rapid device startup, thus maintaining both speed and reliability
