Py_PSNODE

General neural ODE and DAE modules for power system dynamic modeling.

The PyTorch-based ODE solver is developed based on torchdiffeq.

Samples are generated using Py_PSOPS.

Environment

-Windows 7, 8, 10

-Linux

-Python 3.6 or later

Initialization

1. Clone / Pull the codes.

2. Try building neural dynamic models for power system dynamic components such as generator unit, loads, stations, distribution networks, regulators, etc.

TODO

1. Currently, the C++-witten PSOPS can support PyTorch C++ API. However, the python API Py_PSOPS of PSOPS can only successfully load PSOPS.dll/PSOPS.so without PyTorch C++ API. We need to find a way to deal with the violation between Python and PyTorch C++ API when using PyTorch C++ API-integrated PSOPS.dll/PSOPS.so.

2. Add comment.

3. Develop more general modules.

4. Improve performance of the general module and the trained models.
