Computable network models based on GIS data

Distribution grid models right down to every single household? – We show you how!

Geographic Information Systems (GIS) already play an important role for grid operators today. The GIS system often serves as a central data hub through which all network-relevant data is maintained and kept up to date. This helps the grid operator, for example, with the management of building projects, provides correct information to in-field workers during incidents, and serves as a tool for network maintenance.

Power system models based on GIS data

A (partially) automated import of the GIS data into a power system analysis software application such as DIgSILENT PowerFactory can be used to create computable network models that map the entire distribution grid, right down to every individual household. The regular import guarantees the accuracy and validity of data. The power system model is thus linked to the existing GIS data hub and can be maintained without additional effort.
The power system analysis tool allows for the calculation of the entire distribution grid, for example, to examine voltage or overloading violations. This enables on the one hand the assessment of grid connection requests, on the other hand the analysis of optimized grid operation, for example to reduce voltage fluctuations and to minimize network losses. Detailed network models further allow to identify the impact of electric vehicles, heat pumps and distributed generation (e.g. rooftop PV) ensuring the early detection of bottlenecks in low and medium voltage grids and informing the grid operator about preventive measures, where necessary.

We help you with the implementation!

We help you to implement the automated import from your GIS data into your network modelling tool. Using state-of-the-art software tools, even power grids of up to 100,000 nodes and more are calculated within seconds, leaving no limits to the degree of detail you require!
For a possible implementation, we are happy to come to your location and discuss the necessary steps to set up and maintain your GIS-based network model. Afterwards, we will work with you to link the GIS database with your network models. We will also provide your employees with the knowledge and the means to make independent adjustments to the automation themselves at a later date if new challenges arise with regard to data quality.

Expand your modelling analyses

We would be happy to advise and assist you in carrying out further studies that optimize the operation and planning of your power grid. For example, estimates of the coincidence factors of electric cars and heat pumps give an indication about the capacity of the power grid to accommodate these new loads. These take account of expected charging and heating profiles and the regulatory options you have as a network operator to intervene here. These analysis tools help you to carry out a regular check-up of your power grid and make appropriate adjustments to your planning and operating principles. Feel free to be inspired by the references listed below.

In brief:
  • Transfer and automate your GIS data to power system analysis software applications such as DIgSILENT PowerFactory.
  • This allows you to create a network model right down to every individual household connection – and it’s always up-to-date based on your GIS database without additional maintenance.
  • Use the GIS-based network model for the evaluation of grid connection requests, optimized grid operation, and proactive grid planning, e.g. in terms of impact assessment from electric vehicles, heat pumps and distributed generation.
