A programmable logic controller for energy distribution management

GridCal is the answer to today's challenges in the distribution grids. The system is future-proof, as it meets new requirements by remote software updates.

GridCal is an easy-to-install hard- and software system solution for the complete digitization of electrical distribution grids. It is based on a hybrid approach that combines centralized and decentralized components. The management of communication and measurement technology is realized by web-technology using a central management server on site - the GridCal Operator. In contrast, the main data aggregation as well as the decentralized data pre-evaluation are performed through GridCal in the local substation itself. The most significant advantage of the GridCal solution is that not every measurement has to be transferred to the headquarters or into an expensive cloud solution. Only the important data is transmitted, such as overvoltages and undervoltages or device overloads. The causes of all these events can be investigated in the central management server with further detailed grid analyses. In combination with the GridCal Operator, the merging of measurement and device data such as cables and transformers is extremely easy, since the manual data fusion -which is time-consuming and error-prone- is performed by the GridCal Operator. In addition to monitoring, GridCal provides tailored grid analyses for different groups of grid operator staff. Planners, asset managers and senior management all have very different information needs. The GridCal Operator is therefore the perfect assistant for handling current and future tasks in the distribution grids more efficiently and more quickly. At the same time, the GridCal Operator provides different information for different user groups, so that the most important answers can be identified without delay. Real-time tasks such as load management can be performed completely autonomously in the substation. GridCal does not require any special IT infrastructure, as it uses state-of-the-art web technology and standard protocols. Data sovereignty had top priority during the development of the system and therefore never leaves the premise of the grid operator. With the GridCal system solution, customers receive a highly scalable, user-friendly and future-proof solution that combines a data analyst, grid operator and a complete IT infrastructure in one. Using our GridCal solution will lead to a more efficient energy distribution process and reduce overall system losses. It will also enable the integration of more renewable energy and e-mobility while avoiding or delaying costly grid expansion.

Implementation Stories

GridCal by PSInsight GmbH
Implemented by NGN Netzgesellschaft Niederrhein Mbh in Krefeld, Straelen, and Wachtendonk (Germany) in 2020

NGN Netzgesellschaft Niederrhein Mbh, the power grid distribution network operator in Krefeld, Straelen, and Wachtendonk in Germany has equipped hundreds of local network stations with the GridCal system for both medium-voltage network and the low-voltage networks. The system records all network data in real time (incl. switch messages, temperatures and the power quality). Stations are connected to a central server and control center to keep an overview and intervene at a higher level.


Able to connect more photovoltaic systems, combined heat and power plants, heat pumps and charging stations to the existing grids in a shorter time without overloading the networks
