# pommes_craft

A high-level interface to the POMMES energy system modeling tool.

## Description

pommes_craft provides an object-oriented framework for creating, configuring, and solving energy system models. It
allows users to model complex energy systems with various components such as conversion technologies, storage
technologies, and transportation networks across multiple time periods and operational scenarios.

The library is designed to simplify the process of building energy system models by providing a clean API for defining
components, their relationships, and constraints. It then handles the conversion of these high-level descriptions into
optimization problems that can be solved using mathematical programming solvers.

## Features

- Object-oriented API for energy system modeling
- Support for various energy system components:
    - Areas (geographical regions)
    - Conversion technologies (power plants, etc.)
    - Storage technologies (batteries, pumped hydro, etc.)
    - Transport technologies (pipelines, power lines, etc.)
    - Combined technologies
    - Carbon accounting
    - Electricity grid tariffs (TURPE)
- Multi-period modeling (hours, years)
- Investment and operational optimization
- Multiple operational modes and resources
- Integration with mathematical programming solvers
- Comprehensive result analysis and visualization

## Usage

### Basic Example

```python
from pommes_craft import (
    EnergyModel,
    Area,
    Demand,
    ConversionTechnology,
    EconomicHypothesis,
    TimeStepManager,
    LoadShedding,
)
import numpy as np
import polars as pl

rng = np.random.default_rng(seed=0)
# Create energy model
energy_model = EnergyModel(
    name="one_area_conversion_tech",
    hours=list(range(24)),  # 24-hour period
    year_ops=[2020, 2040],  # Two operation years
    year_invs=[2020],  # Single investment year
    year_decs=[2050],  # Single decommissioning year
    modes=[],  # No operation mode
    resources=["electricity", "methane"],  # Basic resources
)

with energy_model.context():
    EconomicHypothesis("eco", discount_rate=0., year_ref=2020, planning_step=20)
    TimeStepManager("ts_m", time_step_duration=1., operation_year_duration=24.)
    area1 = Area("area1")

    # Create electricity demand profiles
    electricity_demand_data1 = [
        {"hour": h, "year_op": y, "demand": 100 * rng.random()}
        for h in energy_model.hours
        for y in energy_model.year_ops
    ]
    electricity_demand1 = Demand(
        name="electricity_demand_area1",
        resource="electricity",
        demand=pl.DataFrame(electricity_demand_data1),

    )
    # Add demands to area
    area1.add_component(electricity_demand1)

    load_shedding = LoadShedding(
        name="electricity_load_shedding",
        resource="electricity",
        max_capacity=0.,
        cost=0.
    )
    area1.add_component(load_shedding)

    # Create gas turbine in area1
    gas_turbine = ConversionTechnology(
        name="gas_turbine",
        factor={
            "electricity": 1.0,  # Produces electricity
            "methane": -2.0  # Consumes methane (negative factor)
        },
        life_span=30.,
        variable_cost=70.,
        invest_cost=800.,
    )

    # Add conversion technology to area1
    area1.add_component(gas_turbine)

energy_model.run()
# Get and analyze results
power_results = energy_model.get_results("operation", "power")
capacity_results = energy_model.get_results("operation", "power_capacity")

print(power_results)
print(capacity_results)
```

- Cannes Lerins H2 - Case study
- Island Energy System Transition
- National Hydrogen Economy Transition
- Regional Energy Transition with Open Data
- Renewable Integration for Industrial Decarbonization
- Urban District Heating Decarbonization

## Testing

Tests are organized in the `pommes_craft/tests` directory:

- `components`: Tests for individual components
- `core`: Tests for core functionality
- `systems`: Tests for complete energy systems

To run all tests:

```bash
python -m pytest
```

To run a specific test file:

```bash
python -m pytest pommes_craft/tests/path/to/test_file.py
```

## Project Organization

The project is organized into several modules:

- `pommes_craft/components`: Contains the components of the energy system model (e.g., Area, Demand, StorageTechnology)
- `pommes_craft/core`: Contains the core functionality of the model (e.g., EnergyModel)
- `pommes_craft/data`: Contains data files for the model
- `pommes_craft/examples`: Contains example usage of the model
- `pommes_craft/tests`: Contains test files
