I’m sorry for replying so late, I hadn’t had time to prepare much for the session yet… I really like your proposal @cbrosig to focus on integrating battery storages with different operation strategies into grid analyses, as that is something we will have to tackle in open_BEA as well. My project partner Daniel is doing a do-a-thon on battery modeling where he will present the battery model SimSES developed by the Technical University of Munich. In open_BEA we want to couple their model to our tool eDisGo.
For the power flow analysis we are currently using pypsa, but we are also working on implementing an OPF for which we will either directly integrate PowerModels or use pandapower. The optimization will be something we can talk about in Leon’s session.
However, the OPF won’t suffice as for example our battery models will most likely be too complex and the time frames too large to do an optimization for. This is where this session could come into play. We could each shortly present our existing approaches as well as some approaches from literature on how storages were considered in distribution grid analyses and then present our ideas for our current projects and discuss them. Questions I would like to discuss are what options are there to couple battery models and grid analyses tools and what are their advantages and disadvantages, what time frames do we need to analyse, how to integrate a Q(U) control. @cbrosig what do you think?
@leon.thurner it sounds like openly available networks will be discussed in this session. Is the integration of battery models into grid analyses something you are working on and/or would be interested in as well?
