E.DIS uses IGP to automate process for connection impact analyses

11.12.19

As a result of the energy transition, millions of new solar pv plants and wind turbines have to be integrated into the distribution grids. Due to the large number of inquiries, the adequate and timely assessment of connection requests for new renewable generators represents an increasing challenge for distribution grid operators. This is particularly the case for grid operators whose grid areas offer attractive conditions for solar or wind energy – such as E.ON’s subsidiary E.DIS Netze. They operate a large network area in the northeastern part of Germany.

In 2018 alone, E.DIS received around 2,500 inquiries for the grid connection of new renewable generation plants. This was an increase of 25 percent compared to the previous year. One reason for the high number of inquiries is the fact that project developers make up to 100 different inquiries for a single planned solar or wind farm. Based on the results, they want to evaluate potential locations with regard to the costs for the grid connection at an early planning stage.

envelio supports E.DIS in this challenge. In June 2019, a online connection check for planners of renewable generators was released on the E.DIS website. This tool provides a first indication of the best possible grid connection point completely automated. After entering location, type and capacity of the generator, the Intelligent Grid Platform automatically determines the closest feasible alternative for a grid connection within a few seconds. With the results, the customer immediately receives information about the distance from the planned location for the plant to a suitable grid coupling point – an essential information for the profitability analysis of many planning projects.

To enable the automated self-service, envelio has developed a comprehensive digital twin of the entire medium-voltage grid of E.DIS. The developed model now serves as the basis for the simulations.

After the successful implementation of the online connection check on the E.DIS Netz website, already the next developments are planned, e.g. the integration of the entire low-voltage grid into the Intelligent Grid Platform.

More information about the project with E.DIS can be found in a press release from E.ON.
