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

Overview

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, 3.7, 3.8]

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. The loop function in Python is way too time-consuming.
