In one of the project’s latest and most important report “INTERPLAN use cases”, the project consortium¬† presents the final results of use cases definition and analysis, as well as future European grid scenarios, which are going to be the basis for further activities of INTERPLAN project, and more precisely for the implementation of the network operation planning tool as planned in the project.¬†

The goal of INTERPLAN is to provide an INTEgrated opeRation PLAnning tool towards the pan-European Network, to support the EU in reaching the expected low-carbon
targets, while maintaining the network security. In order to provide an integrated planning tool, one of the objectives of INTERPLAN is to find suitable scenarios where the future challenges of the Pan-European network and rising technologies are depicted and addressed in order to meet the 2050 goals of the European Union.
INTERPLAN came up with 4 different scenarios, with time horizons to 2030 and 2050, which comprise the different perspectives of development, from small-scale to large-scale, from centralised to decentralised, from conventional generation to renewables, from weak policies to strong policies, inter alia.
The INTERPLAN consortium has also developed and described seven use cases for the INTERPLAN network models (TSO, DSO, and TSO-DSO interface), grid equivalent models and the resulting network operation planning tool.

The seven INTERPLAN use cases are as following :
  • UC1: Coordinated voltage/reactive power control
  • UC2: Grid congestion management
  • UC3: Frequency tertiary control based on optimal power flow calculations
  • UC4: Fast Frequency Restoration Control
  • UC5: Power balancing at DSO level
  • UC6: Inertia management
  • UC7: Optimal generation scheduling and sizing of DER for energy interruption management
Besides, the report presents the key performance indicators, which will be used for evaluating the use case implementation in the planned simulations.
In the further stages of the project, based on the defined use cases and identified EU grid scenarios, a series of showcases as well as required grid equivalent models will be developed for each use case. Finally, a set of dynamic and semi-dynamic simulations for each showcase will be performed, and the possible critical points as well as the possible solutions will be identified.

We would love to know your opinion about our work on operational planning of the future EU grid. Please take a minute to leave us your feedback below, and we will return the favour by informing you about our developments and inviting you to our stakeholder events.
