Solution Overview
Problem
Current SCADA systems face challenges in predicting and controlling low and medium-voltage electrical networks due to the increasing complexity from distributed electricity generation, lack of measured information, and the need for manual data transformation into standardized formats, which is time-consuming and error-prone.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data transformation into standardized formats is used, then data exchange between different network operators is enabled, but the process is time-consuming and error-prone
Solution Approach 1:
The patent replaces manual mechanical data transformation processes with automated computer-implemented methods. The system automatically deserializes network information from various formats, detects topology structures, and transforms data into standardized formats without human intervention, thereby eliminating time loss and errors associated with manual processing.
Solution Approach 2:
The system enables self-service by automatically performing data transformation and standardization tasks. The computer-implemented method autonomously handles the complete workflow of receiving network information, deserializing it, detecting topology, and outputting standardized data without requiring manual operation, making the process both faster and more reliable.
2Adaptability or versatility
If serialized network information is used for data exchange, then compatibility between different systems is improved, but topological system information is lost
Solution Approach 1:
The patent applies preliminary action by detecting and preserving topological system information during the deserialization process. Before finalizing the standardized output, the system actively reconstructs the network topology from the serialized data, ensuring that topological information is recovered and maintained throughout the data exchange process.
Solution Approach 2:
The system introduces an intermediary deserialization and topology detection process between the serialized input format and the standardized output format. This intermediary step acts as a bridge that not only converts formats but also actively reconstructs and preserves topological relationships that would otherwise be lost in serialization.
3Reliability
If conventional state estimation methods are used in distribution grids, then system status can be estimated, but accuracy is insufficient due to lack of measured information
Solution Approach 1:
The patent replaces conventional state estimation methods that rely on pseudo-measurement values with a new approach based on automated topology detection and serialization/deserialization of actual network information. This substitution enables the system to work accurately with the limited measured information available in distribution grids without requiring additional measurement infrastructure.
