Gateway Data Model Translation for Energy System Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of decentralized energy generating systems connected to a supply network makes it difficult for system control units to monitor and control these systems effectively, especially when they use different data models and communication protocols, leading to challenges in seamless information exchange and coordinated control.
Innovation Solution
A method where a gateway translates request and system data from various data models into a metadata model for processing, allowing communication between system control units and energy generating systems without requiring each unit to support all data models, and enabling the gateway to autonomously generate control commands and manage data responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each system control unit and energy generating system supports multiple data models and communication protocols directly, then seamless communication is achieved, but device complexity and implementation difficulty increase significantly
Solution Approach 1:
The patent introduces a gateway as an intermediary component that mediates communication between system control units/energy generating systems and the central system. The gateway translates diverse data models and communication protocols into a unified internal representation, eliminating the need for each endpoint to support multiple protocols directly. This resolves the contradiction by centralizing translation functionality in the gateway while maintaining simple interfaces at the endpoints.
Solution Approach 2:
The gateway is designed as a universal communication interface that handles multiple data models and protocols through a single standardized endpoint. Instead of requiring multiple specialized translators at each device, the gateway provides multi-functional translation capabilities centrally, reducing overall system complexity while maintaining broad compatibility.
2Adaptability or versatility
If multiple translators are deployed at each system control unit and energy generating system to support different data models, then communication flexibility is improved, but the number of components and system complexity increase
Solution Approach 1:
The patent consolidates multiple translator functions into a single gateway component. Instead of deploying separate translators at each system control unit and energy generating system, the gateway merges all translation functionality into one centralized location, reducing the total number of translator components while maintaining the ability to handle diverse data models.
Solution Approach 2:
The gateway acts as a central intermediary that consolidates translation services. All data model translations occur through this single mediator rather than through multiple distributed translators, reducing component quantity while preserving translation capabilities.
3Extent of automation
If a centralized monitoring unit directly communicates with all decentralized energy generating systems, then control coordination is achieved, but communication network complexity and data handling overhead increase
Solution Approach 1:
The patent segments the communication network into hierarchical levels: the gateway operates at the distribution level close to energy generating systems, while the central monitoring unit operates at the system level. This segmentation allows the gateway to handle local translation and preprocessing, reducing the complexity burden on the central monitoring unit and simplifying overall network architecture.
Solution Approach 2:
The gateway serves as an intermediary layer between the central monitoring unit and decentralized energy generating systems. It handles protocol translation and data preprocessing locally, reducing direct communication overhead for the central unit while maintaining coordinated control capabilities across the network.
Data Source
AI summary
A method for the communication of system control units with multiple energy generating systems includes receiving request data from the system control units and system data from the energy generating systems at a common gateway, managing the system data and processing the request data in the gateway, and sending control commands to the energy generating systems and/or data responses to the system control units via the gateway. The request data and/or the system data are received in at least two different data models at the gateway, and translated from their respective data models into a metadata model. The translated system data are managed and the translated request data are processed in the gateway, resulting in data responses and/or control commands in the metadata model that are translated back into the data models of the specific system control units and/or energy generating systems, and transmitted to them by the gateway.
