Schedule deviations have become a bigger problem in the last years in Germanys power system. To tackle this problem a fast local intraday market design is introduced in this paper. It shows a concept of a market clearing process for the 15-minute frame between the closing time of the intraday market and the time of delivery. This fast local intraday market shall reduce the schedule deviation of renewable energies and increase system stability. It also introduces a concept to consider grid limitations in the market process. Therefore the grid sensitivities of the trading partners on the power grid are considered in the matching process. For that a co-simulation was implemented which includes renewable generations, the system operator, the market component and flexibility providers. The results of the simulation show the predicted deviations in a 2025 scenario, the flexibility potentials, the decrease of deviations and the expected costs.
