A simulation framework for assessing the market and grid driven value of flexibility options in distribution grids

The exemplary application focuses on four congestion management concepts, such as flexible tariffs and a market-based flexibility provision. The chosen use case comprises a congested distribution grid with high PV penetration and grid users at the medium and low voltage level. In the use case, the alternatively necessary curtailment of renewable energy can be reduced from 15% to 35% depending on the considered CMM. The most promising CMM (a market-based flexibility provision) reduces the DSO's congestion management costs by 33%, without degrading the grid users' economic situation. Future work will advance the analyses based on a comprehensive database of realistic distribution grid scenarios.
