Power Management Server Protocol Translation for Grid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems face challenges in effectively managing power flow and reverse power flow in a power grid, particularly in coordinating between different communication protocols used by power management servers and local control apparatuses within facilities connected to the grid.
Innovation Solution
A power management method and system that employs a power management server transmitting messages according to a first protocol to a local control apparatus, which then communicates with equipment within a facility using a second protocol, allowing for identification and control of both the local control apparatus and target equipment, enabling appropriate management of power flow and reverse power flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power management server transmits messages to local control apparatus using a first protocol, then communication between server and local control apparatus is established, but the local control apparatus must also communicate with equipment using a second protocol, increasing device complexity
Solution Approach 1:
The patent introduces an intermediary translation layer within the local control apparatus that converts messages between the first protocol (used by power management server) and the second protocol (used by equipment). This mediator component receives messages in the first protocol, translates them to the second protocol for equipment communication, and vice versa, thereby resolving the protocol incompatibility without requiring the server to support multiple protocols directly.
2Adaptability or versatility
If the system supports multiple communication protocols for different devices, then adaptability is improved, but the difficulty of detecting and measuring control targets increases
Solution Approach 1:
The patent segments the control message structure into distinct fields that separately identify the control target (local control apparatus vs. equipment) and the control content. By dividing the message into structured segments with clear delimiters and identification fields, the system can easily parse and identify control targets regardless of which protocol is being used, reducing the difficulty of detection and measurement.
3Adaptability or versatility
If the system manages both power flow and reverse power flow control, then functionality is improved, but the loss of information increases due to protocol translation
Solution Approach 1:
The patent implements a feedback mechanism where the local control apparatus sends acknowledgment messages back to the power management server to confirm successful reception and execution of control commands. The feedback loop includes verification steps that check whether the translated control message was correctly interpreted by the equipment, allowing the system to detect and correct any information loss or translation errors that may have occurred during protocol conversion.

AI summary
A power management method comprises a step A of transmitting a first message from a power management server to a local control apparatus according to a first protocol. The power management server manages a facility connected to a power grid. The local control apparatus is provided in the facility. A communication between the local control apparatus and an equipment provided in the facility is performed according to a second protocol different from the first protocol. The step A includes a step of transmitting the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.
