Due to the increasing number of renewable energy systems and new loads like electric vehicle charging stations or heat pumps, it is necessary to try many different innovative strategies to keep the distribution grid within its voltage and current limits. One popular solution is to implement a smart grid system which calculates the complete grid state by some measurements and reacts in real time for example by decreasing the infeed of renewable energies in case of voltage limit violations. This paper focuses on local flexibility markets according to the BDEW traffic light concept presented in [1], which describes a marked-based approach to prevent limit violations in advance. The concrete design of realizing local flexibility markets in low voltage grids is already formulated in [2]. Now it has to be evaluated in a field test, for which the developed software has to be connected with an already existing smart grid system. It will be explained which preperations have to be done before starting an active field test period, how to realize future load and generation situations and how to simulate a market action in the field test grid. There will be also an outlook on how this concept could be realized for combined voltage level solutions.
