Hi Klinki,
I developed a PreferDcPower optimizer that is specifically designed for HybridEss systems and also supports a mixed ESS-Cluster consisting of both HybridEss and AC-coupled ESS.
You might find the discussion and implementation useful for your use case:
- Forum discussion: Neuer Optimizer/Logik für mehrere Hybrid ESSes - #54 by MrT
- PR: PreferDcPowerOptimizer for improved multi-ESS hybrid coordination by timo-schlegel · Pull Request #3661 · OpenEMS/openems · GitHub
Maybe this already solves (or at least addresses) the issue you’re seeing.
