Distributed Power Supply Control for Criteria-Based Source Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems lack the ability to flexibly select and operate distributed power sources based on specific criteria, such as power demand and operational objectives, leading to inefficient energy management in decentralized power networks.
Innovation Solution
A control device that communicates with distributed power supplies, acquires performance and running information, power demand data, and selection criteria to create an operation plan, prioritizing power supply combinations based on criteria like economic efficiency, environmental friendliness, or low noise, and controls the selected power sources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple distributed power supplies are operated simultaneously to meet power demand, then power supply reliability is improved, but system complexity and control difficulty increase
Solution Approach 1:
The control device changes operational parameters of distributed power supplies based on selection criteria. It dynamically adjusts which power supplies are operated by evaluating multiple parameters (power demand amount, performance information, running information) and selecting optimal combinations, thereby maintaining reliability while managing complexity through parameter-based control
Solution Approach 2:
The system dynamically selects and operates distributed power supplies based on real-time conditions. The control device continuously evaluates power demand, performance, and running information to determine optimal power supply combinations, making the system adaptable rather than static, which manages complexity through dynamic decision-making
2Productivity
If distributed power supplies are selected based on multiple criteria (economic efficiency, environmental friendliness, noise), then operational efficiency is improved, but selection complexity increases
Solution Approach 1:
The control device evaluates distributed power supplies based on multiple selectable criteria (economic efficiency, environmental friendliness, noise levels). By allowing dynamic selection of evaluation parameters, the system achieves operational efficiency through criterion-based optimization while managing selection complexity through structured parameter evaluation
Solution Approach 2:
The control device segments the selection process into distinct evaluation dimensions (economic efficiency, environmental friendliness, noise). By dividing the complex selection task into separate evaluable criteria, the system improves operational efficiency through targeted evaluation while reducing selection complexity through structured segmentation
3Measurement precision
If comprehensive performance and running information is collected from all distributed power supplies, then selection accuracy is improved, but information processing load increases
Solution Approach 1:
The control device preliminarily collects and stores performance information and running information from distributed power supplies before the selection process. By preparing this data in advance, the system achieves accurate selection based on comprehensive information while managing processing load through pre-organized data structures
Solution Approach 2:
The control device extracts only the necessary performance and running information needed for selection from the comprehensive data set. By taking out only the relevant parameters (power demand amount, performance metrics, running status) required for evaluation, the system achieves selection accuracy without processing the entire information set
