Federal Network Agency, BNetzA – “Opportunities and Challenges for Optimization in Grid Planning”

Winfried Lorenzen

Optimization tools have become essential for grid planning processes. From modelling future energy markets to finding optimal asset placements, it can be an invaluable part of the grid planning toolbox.

Until recently there was only limited control over the power flow in the grid. This can lead to problematic power flows, where some lines are highly loaded while others have free capacities.

Adding more and more devices for power flow control—like phase shifting transformers or FACTS—allows for better use of existing high voltage lines. This can reduce the need for congestion management as well as the need for grid expansion.

At the same time, grid operation gets more complex, since a growing number of devices must be coordinated with all concerned TSOs. In the context of grid planning, this bears the danger of over-optimizing the system by assuming unrealistic requirements on the grid operation.

Furthermore, interpretation of power flow results is getting harder, which complicates decisions about specific grid expansion projects.

Here, an overview over the current state of grid optimization in the context of the current German Grid Development Plan will be given, demonstrating the opportunities but also the challenges of optimization in grid planning.

National Centre for Nuclear Research (NCBJ) – “Overview of the decision-support tools based on optimization for TSOs (& DSOs)”

Endika Urresti Padrón

Nowadays, the complexity of power system operations is growing due to the increase of renewables, European integration, DER integration, etc. Therefore, the operators are forced to rely on optimization tools in all their activities: investment expansion planning, European market decisions, TSO-DSO coordination, remedial actions operations, etc. NCBJ is a research institute which provides several optimization tools to operators in order to support their internal processes.

TenneT – “Redispatch Optimization in Germany”

Daniel Fraß

The lecture describes the general problem of Redispatch optimization in Germany. The situation of the past years with the typical congestions and Redispatch quantities will be briefly discussed and the relevant input variables and constraints for optimization will be described.

Furthermore, the current operational planning processes and their international integration are outlined. The challenges in practical implementation, such as the provision of required input data, data quality and timeline for process implementation, will be addressed.

Finally, the new challenges with the RD2.0 process, especially the multiplication of technical resources to be considered, are described. Approaches to solutions through clustering of technical resources and less complex technical restrictions for the considered clusters are presented.

“From Grid Planning to Congestion Management – Serving the Power Industry with an Optimization Framework”

Simon Krahl

The development of the demand for redispatch measures in the course of the German “Energiewende” from 2011 to today resulted in a strong increase in the need for optimization tools.

Optimization tools for remedial actions have been developed for the entire range from grid planning to network operation. In grid planning, the operational measures must be simulated – for this purpose, the use of optimization tools has proven to be useful. In disconnection planning, the feasibility of measures is also assessed in consideration of the resulting need for redispatch, so that optimization methods are also used here. In capacity allocation trading capacities are maximized based on available potentials for remedial actions. For operation, the TSOs in Germany are obliged according to the legislation to make the most cost-efficient selection of remedial actions, which requires complex optimisation tools.

The required optimization problems differ from each other in terms of modelling depth and accuracy depending on the planning stage and process, but in essence they are very similar problems. A modular optimization framework can therefore be used to efficiently address all of these optimization tasks.
