Distributed Power Supply Controller Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed power supply systems, conflicts between messages from power management servers and equipment management servers can hinder proper control of distributed power supplies, particularly when entities managing these systems are different, leading to potential disruptions in power supply-demand balance.
Innovation Solution
A distributed power supply system that includes a communicator to receive messages from both power management and equipment management servers, with a controller prioritizing control based on messages from the equipment management server in case of conflicts, ensuring maintenance is performed effectively over power supply-demand balance instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the controller prioritizes power management server messages for maintaining power supply-demand balance, then power grid stability is improved, but equipment maintenance is delayed causing reliability deterioration
Solution Approach 1:
The patent introduces a message priority mechanism as an intermediary layer between the power management server and equipment management server. The controller acts as a mediator that receives messages from both servers, determines their priority levels, and executes them in a controlled sequence. This intermediary mechanism resolves the conflict by allowing both power management and equipment maintenance objectives to be fulfilled without direct interference between the two management systems.
2Reliability
If the controller prioritizes equipment management server messages for maintenance, then equipment reliability is improved, but power supply-demand balance is disrupted
Solution Approach 1:
The patent implements a dynamic message priority adjustment mechanism where the controller can flexibly change the priority of messages from different servers based on current system conditions. When power supply-demand balance is critical, power management messages are given higher priority; when equipment maintenance is urgent, equipment management messages are prioritized. This dynamic adjustment allows the system to adapt to changing conditions and resolve conflicts appropriately.
3Adaptability or versatility
If the system accepts messages from multiple management servers, then system functionality is improved, but control complexity increases
Solution Approach 1:
The patent segments the control function into distinct modules: a message reception module that accepts messages from multiple servers, a priority determination module that evaluates message importance, and an execution module that carries out control actions. This segmentation allows the system to handle multiple management servers systematically without overwhelming complexity, as each module performs a specific function independently.
Data Source
AI summary
The distributed power supply system includes: a communicator configured to receive a first message from a power management server configured to control the distributed power supply and receive a second message from an equipment management server configured to monitor the distributed power supply; and a controller configured to control the distributed power supply based on the first message and the second message. If the first message and the second message conflict with each other, the controller controls the distributed power supply based on the second message preferentially over the first message.
