FPowerKit - A power distribution network calculation component
This is a package designed for power distribution network description and solving.
This package is affiliated to V2Sim, an open-aource microscopic V2G simulation platform in urban power and transportation network. If you are using the modified DistFlow model in this package, please cite the paper：

Solvers available
There are multiple solvers can be used in FPowerKit.
- Power flow calculation
- Newton-Raphson: Classical method for power flow calculation. (GIL-free Compatible)
- OpenDSS: Call external OpenDSS for distribution network solving.
- Optimal power flow (OPF)
- DistFlow: A classical OPF model for radial distribution network, with both quadratic and linear objective of minimal active generation cost.
- LinDistFlow: A typical simplification of DistFlow.
- LinDistFlow2: A GIL-free compatible version of LinDistFlow, only supporting linear objective.
There are also some abstract solvers for users to customize:
- Combined Solver: Combine two solvers to accomplish both OPF and accuracte power flow calculation. For example, use LinDistFlow + OpenDSS to get the optimal generation and the accurate power flow. The only GIL-free compatible combination is LinDistFlow2 + Newton.
- Manual Solver: Allow user to customize constraints
Installation options
If you want to use different features, install with different command:
| Feature | Command |
|---|---|
| Only grid description | pip install fpowerkit |
| Y matrix & Newton | pip install fpowerkit[newton] |
| OpenDSS | pip install fpowerkit[dss] |
| DistFlow | pip install fpowerkit[distflow] |
| LinDistFlow | pip install fpowerkit[ldf] |
| All | pip install fpowerkit[full] |
Secondary development on this package requires all features.
Introduction
There are 3 modes for this package to work:
-
Optimal power flow (OPF): Use cvxpy to solve the optimal power flow and determine the output of the generators.
-
Power flow calculation: Use OpenDSS/Newton-Raphson method to solve the power flow.
-
Hybrid: Use OPF to determine the initial value, and then use OpenDSS/Newton-Raphson to perform accurate calculation.
