Interactive dashboard for visualizing and analyzing PyPSA energy system networks

PyPSA Explorer

Interactive dashboard for visualizing and analyzing PyPSA energy system networks. Built with Dash and Plotly, PyPSA Explorer provides a comprehensive web interface for exploring energy system models with powerful filtering and visualization capabilities.

Features

📊 Interactive Visualizations

• Energy Balance Analysis: Timeseries and aggregated views of energy flows
• Capacity Planning: Visualize optimal capacity distribution by carrier and region
• Economic Analysis: CAPEX and OPEX breakdowns across the system
• Network Maps: Interactive geographical visualization of network topology
• Multi-Network Support: Load and compare multiple networks seamlessly

🎯 Advanced Filtering

• Filter by energy carrier (sector)
• Filter by country/region
• Dynamic updates across all visualizations
• Tab-specific filter behavior

🚀 Production Ready

• Well-structured, modular codebase
• Comprehensive type hints
• Extensive test coverage
• CI/CD pipeline integration
• Professional documentation

Installation

From PyPI (Recommended)

pip install pypsa-explorer

From Source

git clone https://github.com/openenergytransition/pypsa-explorer.git
cd pypsa-explorer
pip install -e .

Development Installation

git clone https://github.com/openenergytransition/pypsa-explorer.git
cd pypsa-explorer
pip install -e ".[dev]"
pre-commit install

Quick Start

Command Line Interface

Launch the landing page and drag-and-drop networks or load the bundled example:

pypsa-explorer

Run with your own network:

pypsa-explorer /path/to/network.nc

Run with multiple networks:

pypsa-explorer /path/to/network1.nc:Label1 /path/to/network2.nc:Label2

Custom host and port:

pypsa-explorer --host 0.0.0.0 --port 8080

Production mode (no debug):

pypsa-explorer --no-debug

Python API

from pypsa_explorer import run_dashboard

# Run with default network
run_dashboard()

# Run with custom network
run_dashboard("/path/to/network.nc")

# Run with multiple networks
networks = {
    "Scenario A": "/path/to/network1.nc",
    "Scenario B": "/path/to/network2.nc",
}
run_dashboard(networks, debug=True, host="0.0.0.0", port=8050)

# Run with Network objects
import pypsa
n1 = pypsa.Network("network1.nc")
n2 = pypsa.Network("network2.nc")

run_dashboard({"Network 1": n1, "Network 2": n2})

Programmatic App Creation

from pypsa_explorer import create_app

# Create app instance
app = create_app(networks_input="/path/to/network.nc", title="My Dashboard")

# Run with custom server
app.run(debug=True, host="0.0.0.0", port=8050)
