Inverter Port Power Control for Real-Time Load Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power adjustment methods for inverters in small power grids lack flexibility, as they adjust power based on preset values for different time periods, leading to inefficiencies and potential instability.
Innovation Solution
A power adjustment method that dynamically adjusts the power of inverter ports based on the first and second power values of the load at different moments and changes in power supply type, using a power adjustment apparatus to manage the inverter's power output and input ports accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power adjustment is based on preset values for different time periods, then power adjustment can be implemented, but power adjustment flexibility is low
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring real-time load power values and dynamically modifying inverter output power based on detected power supply type changes and load conditions, replacing static preset-based adjustment with adaptive real-time control that responds to actual system state
Solution Approach 2:
The system employs feedback mechanisms by detecting the power supply type (mains or non-mains), monitoring load power values in real-time, and using this information to automatically adjust inverter power output, creating a closed-loop control system that continuously adapts to changing conditions
2Productivity
If power adjustment is based on preset values, then implementation is simple, but power adjustment cannot adapt to real-time load changes
Solution Approach 1:
The inverter system performs self-adjustment by automatically detecting power supply type changes and load power conditions, then autonomously modifying its own power output without requiring external intervention or complex manual configuration, enabling the system to serve itself in adapting to real-time conditions
3Reliability
If power adjustment is not optimized for power supply type changes, then control is simple, but power stability deteriorates
Solution Approach 1:
The system performs preliminary detection of power supply type changes and proactively adjusts power output before instability can occur, identifying transitions between mains and non-mains power supply and preemptively modifying inverter operation to maintain stability throughout the transition process

AI summary
This application relates to the field of power technologies, and provides a power adjustment method and apparatus and a computer-readable storage medium, to improve power adjustment flexibility of a port of an inverter. The method includes: obtaining a first power value of a load at a previous moment and change information of a power supply type of the load and a second power value of the load at a current moment, where the power supply type includes mains power supply or non-mains power supply; adjusting a power of a non-load output port of an inverter based on the change information; and adjusting a power of a load output port of the inverter based on a magnitude relationship between the first power value and the second power value.
