Further development of the low-voltage cockpit (NSC)
Project duration: 9 months
Brief description
The Low Voltage Cockpit (NSC) is a software tool for monitoring and automated control of low voltage networks in accordance with the legal requirements of the Energy Industry Act (EnWG). The aim of the project is to further develop the MVP created in phase 1 into a productive solution that meets the regulatory, procedural, and safety requirements for use by distribution network operators. PTA GmbH is responsible for developing the user interface as well as the reporting and analytics modules that enable visualization, analysis, and interaction. Technologically, the system is based on a microservices architecture with Java/Spring Boot in the backend, Angular in the frontend, and Kafka as the message bus. WebSockets ensure the transmission of real-time data. The NSC supports network operators in creating transparency in low-voltage networks, identifying bottlenecks at an early stage, and controlling controllable consumption and generation facilities in a way that benefits the network.
Supplement
The NSC is operated on a containerized platform (Kubernetes) and uses a microservices architecture with Java/Spring Boot, Kafka, PostgreSQL, and Angular. It is designed for two operating modes: a non-KRITIS instance and a KRITIS instance with increased security requirements for critical control activities. PTA GmbH is responsible for the design and implementation of the graphical user interface, the integration of the database modules, and the display of network and status information as well as measured values in real time. This includes functions for visualizing network objects, status and event data, mandatory publications, and documentation. Automated end-to-end tests with Playwright and static code analyses are used for quality assurance. Further development is carried out in an agile manner in close coordination with the customer and the cooperative.
Subject description
With increasing electrification, particularly through heat pumps, charging infrastructure, and photovoltaics, the load on the low-voltage level is rising. The NSC supports distribution network operators in transparently monitoring the network situation, identifying bottlenecks, and implementing network-related control measures in accordance with the legal requirements of the EnWG. By collecting and analyzing measurement and grid data, the NSC enables a data-based assessment of expansion requirements and short-term grid-oriented control of consumption and generation facilities. This reduces grid expansion costs and facilitates the integration of decentralized facilities. In Release 2, the system will be expanded to include the control of generation facilities. In the future, the NSC will be able to regulate both controllable consumption facilities (SteuVE) and generation facilities (EZA) as needed, thereby contributing significantly to the secure, economical, and regulatory-compliant transformation of energy.
