Maybe the time has finally come to link up PyPSA and PowerDynamics, like we promised in proposals 8ish years ago ;)

PowerDynamics specifically contains features to initialize a valid initial state from a power flow solution, and an initial model library for power grid components.

We have an easy* to use prototype of the IEEE39 bus system. Get in touch if you want to use this!

- Heterogeneous node and edge dynamics
- Modular equation-based modeling
- Symbolic simplification
- Parallel on CPU and GPU (experimental)
- Automatic Differentiation compatible (enables NeuralODE on nodes, parameter fitting, sensitivity analysis, optimization of dynamic properties, etc...)

Congratulations! Incidentally we just released PowerDynamics.jl 4.0, the latest iteration of the dynamics work we started when PyPSA was still young. A more or less complete rewrite and the first version that is actually suitable for Engineering level dynamics studies.

Habermas worked extensively on the conditions under which open discourse can establish truths (including moral truths).

Discourse Ethics, communicative rationality, and hierarchyless discourse, are key terms. From this analysis the outcome of the internet is maybe not so surprising.
