powergridforge 1.1.3

Power system configuration and optimization toolkit.

GridForge

GridForge helps build optimization-ready power-system cases from standard PYPOWER/MATPOWER grids. It lets you describe grid edits in YAML, generate a structured Excel workbook, attach bus-level time-series data, and load the result into Python for your own optimization model.

GridForge is useful when a standard test case is not enough: for example, when you need custom assets such as load, solar, wind, or storage, time-series data attached to selected buses, and convenient access to the final case in CVXPY.

Workflow

base PYPOWER/MATPOWER case
  -> grid configuration YAML
  -> generated Excel workbook
  -> bus-data assignment YAML
  -> bus_<BUS_IDX>.csv files
  -> Grid(...) and Data(...) classes for efficient access to the case and data
  -> user-defined optimization model

The grid configuration YAML can be written manually or created with the visual app. The bus-data assignment step is separate because it depends on the generated BUS_IDX values in the workbook.

Installation

Install the latest release from PyPI:

pip install powergridforge

To run the examples and edit the docs, clone the repository:

git clone https://github.com/xuwkk/gridforge.git
cd gridforge
python -m venv .venv
source .venv/bin/activate
pip install -e ".[full]"

What You Need First

GridForge does not invent the grid design automatically. Before constructing a case, prepare:

• a grid configuration YAML that selects a base case and describes static grid edits, see configuration.md for details.
• a bus-data assignment YAML that declares which time-series signals should be mapped to generated buses, see bus-data-assignment.md for details.
• source CSV files if you want to materialize time-series data.

For a first run, use the prepared 14-bus example in a source checkout of this repository.

14-Bus Example

The worked unit-commitment example is in examples/14bus_uc/.

Important files:

• 14bus_config.yaml: grid configuration rules.
• 14bus_config.xlsx: generated static workbook.
• 14bus_data_assignment.yaml: bus-data signal template used to generate bus assignments.
• 14bus_data/: generated bus_<BUS_IDX>.csv files.
• 14bus_example.py: runnable end-to-end example.
• 14bus_uc.ipynb: interactive notebook for inspecting the case, data, topology, and UC model setup.

Run the example from the repository root:

python examples/14bus_uc/14bus_example.py

Or open the notebook:

jupyter lab examples/14bus_uc/14bus_uc.ipynb

The same workflow can be called from Python:

from gridforge.construct import construct_grid_config
from gridforge.data import (
    load_bus_data_assignment,
    prepare_bus_data,
)
from gridforge.opt import Grid, Data

config_yaml = "examples/14bus_uc/14bus_config.yaml"
config_xlsx = "examples/14bus_uc/14bus_config.xlsx"
assignment_yaml = "examples/14bus_uc/14bus_data_assignment.yaml"
resolved_assignment_yaml = "examples/14bus_uc/14bus_data_assignment_resolved.yaml"
data_dir = "examples/14bus_uc/14bus_data"
source_data_dir = "data/bus_data"

construct_grid_config(config_yaml, config_xlsx, random_seed=404)

assignment_template = load_bus_data_assignment(assignment_yaml)
assignment, _ = prepare_bus_data(
    grid_xlsx_path=config_xlsx,
    source_data_dir=source_data_dir,
    signals=assignment_template["signals"],
    output_data_dir=data_dir,
    resolved_assignment_path=resolved_assignment_yaml,
    random_seed=404,
)

grid = Grid(config_xlsx, verbose=0)
data = Data(
    grid_xlsx_path=config_xlsx,
    data_dir=data_dir,
    sheet_names=["load", "solar", "wind"],
)

print(grid.gen.pmax)
print(grid.branch.ptdf.shape)
print(grid.load.Cbus.shape)
print(data.get_series("load").shape)

Visual Config App

The visual app helps create and inspect the grid configuration YAML used in the first stage.

Launch it after installing the app dependencies, for example with pip install -e ".[full]" from a source checkout:

gridforge-app

From a local checkout:

streamlit run gridforge/config_app.py
