Economic dispatch of flexibility options for Grid services on distribution level

Due to the ascending capacity of Renewable Energy Sources, new challenges arise in the operation of distribution grids. Existing Smart Grid solutions have shown, that direct control interventions into distributed generation and demand facilities may contribute to ensure a reliable and economic grid operation. In extension of these direct control methods, this paper presents a new approach for an economic dispatch of flexibility options for grid services on distribution level. The developed modelling framework for a local flexibility market offers the possibility to simulate the market behavior. The modular set up of a grid operator model and several unit operator models allows research on the interaction between both domains in order to find the economically optimal operation mode for avoidance of critical grid states. The results of a one year simulation of a distribution grid are showing the advantageousness of the system.
