# KPI Calculator

A Python package for calculating Key Performance Indicators (KPIs) for heat network designs from ESDL files.

Part of the 'Nieuwe Warmte Nu Design Toolkit' project.

## Quick Start

```python
from kpicalculator import calculate_kpis

# Automatic: Loads time series from InfluxDB references in ESDL
results = calculate_kpis(esdl_file="path/to/model.esdl")
print(f"Total CAPEX: {results['costs']['capex']['All']} EUR")
```

[See test](unit_test/test_examples.py)

## Installation

```bash
pip install git+https://github.com/Project-OMOTES/kpi-calculator.git@feature/database-connectivity # From development branch

pip install kpi-calculator  # Coming soon
```

## Features

**KPI Categories:**
- **Cost**: CAPEX, OPEX, NPV, LCOE
- **Energy**: Consumption, production, efficiency
- **Emissions**: Total CO2, emissions per MWh

**Data Sources:**
- ESDL files with embedded cost data
- InfluxDB time series (automatic)
- XML time series files (testing)
- Pandas DataFrames (simulator integration)

**Architecture:**
- Modular adapters, calculators, and managers
- Full type safety with Pydantic v2
- Secure InfluxDB integration ([setup guide](doc/SECURE_DATABASE_SETUP.md))
- Comprehensive test coverage (83%+)

## Usage

### Basic Usage

```python
from kpicalculator import calculate_kpis

# Production: Automatically loads time series from InfluxDB profiles in ESDL
results = calculate_kpis(esdl_file="model.esdl")

# With optional parameters
results = calculate_kpis(
    esdl_file="model.esdl",
    system_lifetime=30  # Default: 30 years
)

# Testing: Override with XML file when database is unavailable
results = calculate_kpis(
    esdl_file="model.esdl",
    time_series="timeseries.xml"  # For testing only
)
```

[See tests](unit_test/test_examples.py)

### Data Source Options

**Cost Data** (priority order):
1. ESDL `costInformation` elements (production default)
2. CSV files (testing override only)

**Time Series Data** (priority order):
1. Pandas DataFrames (in-memory, simulator integration)
2. InfluxDB profiles (automatic from ESDL InfluxDBProfile references)
3. XML files (testing override when database unavailable)
4. None (asset-level calculations only)

**Note:** In production, time series are automatically loaded from InfluxDB when your ESDL file contains InfluxDBProfile references. You only need to specify `time_series` parameter for testing with XML files.

**Database Setup:** See [Secure Database Setup](doc/SECURE_DATABASE_SETUP.md) for configuring InfluxDB credentials using environment variables or secure configuration files.

### Simulator Integration

Pass time series data directly as pandas DataFrames:

```python
import pandas as pd

# Create time series data indexed by datetime
datetime_index = pd.date_range("2024-01-01", periods=24, freq="H")

timeseries_data = {
    "asset_id_1": pd.DataFrame({
        "mass_flow": [2.5, 2.6, 2.4, ...],
        "temperature": [353.15, 353.20, ...],
        "heat_supplied": [100000, 102000, ...],
    }, index=datetime_index),

    "asset_id_2": pd.DataFrame({
        "heat_demand": [80000, 81000, ...],
    }, index=datetime_index),
}

results = calculate_kpis(
    esdl_file="model.esdl",
    timeseries_dataframes=timeseries_data,
    system_lifetime=30
)
```

**Requirements for `timeseries_dataframes`:**
- **Keys**: Asset IDs matching ESDL file
- **Values**: DataFrames with datetime index and property columns
- **Properties**: Any of `mass_flow`, `pressure`, `temperature`, `volume_flow`, `heat_supplied`, `heat_demand`, `velocity`, `pressure_loss`, `heat_loss`

**Integration example:** The [simulator-worker](https://github.com/Project-OMOTES/simulator-worker) converts its port-level tuple-column format to asset-level DataFrames before calling `calculate_kpis()`. See [integration guide](https://github.com/Project-OMOTES/simulator-worker/blob/feature/kpi-calculator-integration/doc/SIMULATOR_WORKER_KPI_INTEGRATION.md).

[See test: test_timeseries_dataframes_integration](unit_test/test_examples.py)

### Testing with CSV Override

```python
# Override ESDL costs for testing
results = calculate_kpis(
    esdl_file="model.esdl",
    pipes_cost="test_pipes.csv",
    assets_cost="test_assets.csv"
)
```

[See test](unit_test/test_examples.py)

<details>
<summary><b>Advanced: Batch Processing</b></summary>

```python
from kpicalculator import KpiManager

# Batch process multiple scenarios
manager = KpiManager("unit_conversion.csv")
scenarios = [
    {"file": "scenario_1.esdl", "lifetime": 25},
    {"file": "scenario_2.esdl", "lifetime": 30},
    {"file": "scenario_3.esdl", "lifetime": 35}
]

for scenario in scenarios:
    manager.load_from_esdl(scenario["file"])
    results = manager.calculate_all_kpis(system_lifetime=scenario["lifetime"])
    # Compare results across scenarios
```

[See test](unit_test/test_examples.py)
</details>
