The software to be developed is the so-called Low Voltage Cockpit (NSC). It is a software tool designed for monitoring and automated control of low voltage networks. The NSC is being developed in five development packages, which are further divided into modules. PTA GmbH is responsible for Package C – Low Voltage Cockpit GUI, Data Base Module, and Documentation Module.
Supplement
The NSC primarily aims to ensure transparency in low voltage networks. Additionally, tools to simplify mandatory publications and documentation will also be developed. Technically, the module uses Java with Spring Boot and a microservices architecture in the backend. Angular is employed in the frontend. WebSockets are used for real-time display of measurement data. Kafka facilitates communication between the microservices to meet the requirements for high availability and scalability. Due to the high quality standards, both static code analysis and automated tests must be conducted. End-to-end tests are performed using Playwright.
Subject description
The transformation of the energy system, particularly the expansion of wall boxes, heat pumps, and photovoltaic systems, is leading to higher consumption and generation loads in the low voltage network. To prevent overloading of network infrastructure, expansion measures are necessary. To reduce the costs of network expansion, measurement data and a software system for data analysis are essential, enabling distribution network operators to achieve observability of the low voltage level. This will be ensured with the software to be developed. Another goal to be achieved through the use of the NSC is the control of consumers in the low voltage network. By selectively and temporarily limiting the power of individual consumers, the integration potential of consumers in the low voltage level can be increased in the short term without requiring network expansion measures.
