Local Power Control Message Prioritization for Reverse Power Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems lack the ability to determine the appropriate use type of control messages, leading to conflicts and inefficiencies in controlling power flow and reverse power flow due to undefined use types.
Innovation Solution
Incorporating source identification information into control messages to identify the purpose and issuer, allowing the local control apparatus to prioritize and execute control instructions effectively, thereby stabilizing the power grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control messages are sent without source identification information, then the system structure remains simple, but the local control apparatus cannot determine the appropriate use type leading to control conflicts
Solution Approach 1:
The source identification information is nested within the control message structure, allowing the local control apparatus to extract and process the issuer and purpose information without requiring a completely new message format. This nested approach enables reliable control execution while maintaining relatively simple message structures.
Solution Approach 2:
The source identification information acts as an intermediary element within the control message that enables the local control apparatus to determine the appropriate use type. This intermediary component resolves the conflict between maintaining simple message structures and achieving reliable control execution.
2Reliability
If multiple control messages with different use types are processed without priority differentiation, then the control system remains simple, but conflicts arise in controlling power flow and reverse power flow
Solution Approach 1:
The priority levels for different use types are predetermined and stored in the local control apparatus before control conflicts occur. When control messages are received, the apparatus simply compares the priority levels without complex real-time decision-making, ensuring power grid stability while keeping control logic relatively simple.
Solution Approach 2:
The system introduces priority level parameters associated with different use types to differentiate control message importance. By changing the parameter structure to include priority information, the system can reliably resolve control conflicts without requiring complex control logic.
3Productivity
If the local control apparatus executes all control messages without priority differentiation, then the operation remains simple, but efficiency is reduced due to control conflicts and coordination issues
Solution Approach 1:
Priority levels are predetermined and associated with each use type before control execution. The local control apparatus efficiently processes multiple control messages by simply comparing pre-established priority levels, significantly improving control execution efficiency without requiring complex real-time processing logic.
Solution Approach 2:
The system uses standardized priority level indicators that can be copied and applied across different control messages and use types. This standardization enables efficient message processing while maintaining relatively simple processing logic, as the same priority comparison mechanism applies to all control messages.

AI summary
A power management method according is provided with a step A of sending a control message from a power management server to a local control apparatus and a step B of performing, on the basis of source identification information that identifies a source of the control message, by the local control apparatus, control based on the control message. The source identification information is associated with a use type that identifies use of the control message.
