# Optimizing energy systems with *aristopy*
The Python package *aristopy* is a framework for modeling and optimizing the
design and operation of energy systems.
The name of the framework is derived from the great Greek thinker Aristotle.
For Aristotle, planning and the wise use of human goods represented great virtues.
Transferred to today's time and the design of energy systems, this implies using
appropriate tools that support the planning process and contribute to an
optimal use of the available resources (money, fuel, etc.).
## Selected highlights
* Flexible modeling of energy systems with only a small number of basic
components (Source, Sink, Conversion, Bus, Storage) and a comprehensive API.
* Manual scripting of component constraints to enable all types of
mathematical modeling classes (linear \[LP\], mixed-integer linear
\[MILP\], mixed-integer non-linear \[MINLP\], etc.).
* Declaration of persistent models to quickly run models iteratively
after applying small changes (e.g., add an integer-cut constraint).
* Auto-generated visualization of the optimization results with
flexible plotting routines.
## Documentation
The package documentation is hosted on readthedocs.org and can be accessed
[here](https://aristopy.readthedocs.io/en/latest/index.html).
## Installation
Before you can create your first optimization model with *aristopy*, you need
to make sure you have Python and *aristopy*, and at least one suitable
mathematical solver installed on your machine.
The installation of *aristopy* in your current environment can easily be
executed from the command line via pip:
```python
pip install aristopy
```
More detailed installation instructions can be found in the
[documentation](https://aristopy.readthedocs.io/en/latest/installation.html).
## Examples
The code of the first simple example from the examples directory, shown
below, illustrates the notation of *aristopy*.
A detailed description of the code is provided in the
[documentation](https://aristopy.readthedocs.io/en/latest/model_to_get_started.html).
```python
import aristopy as ar
# Create basic energy system instance
es = ar.EnergySystem(
number_of_time_steps=3, hours_per_time_step=1,
interest_rate=0.05, economic_lifetime=20)
# Add a gas source, two different conversion units and sinks
gas_source = ar.Source(
ensys=es, name='gas_source', commodity_cost=20, outlet=ar.Flow('Fuel'))
gas_boiler = ar.Conversion(
ensys=es, name='gas_boiler', basic_variable='Heat',
inlet=ar.Flow('Fuel', 'gas_source'), outlet=ar.Flow('Heat', 'heat_sink'),
capacity_max=150, capex_per_capacity=60e3,
user_expressions='Heat == 0.9 * Fuel')
chp_unit = ar.Conversion(
ensys=es, name='chp_unit', basic_variable='Elec',
inlet=ar.Flow('Fuel', 'gas_source'),
outlet=[ar.Flow('Heat', 'heat_sink'), ar.Flow('Elec', 'elec_sink')],
capacity_max=100, capex_per_capacity=600e3,
user_expressions=['Heat == 0.5 * Fuel',
'Elec == 0.4 * Fuel'])
heat_sink = ar.Sink(
ensys=es, name='heat_sink', inlet=ar.Flow('Heat'),
commodity_rate_fix=ar.Series('heat_demand', [100, 200, 150]))
elec_sink = ar.Sink(
ensys=es, name='elec_sink', inlet=ar.Flow('Elec'), commodity_revenues=30)
# Run the optimization
es.optimize(solver='cbc', results_file='results.json')
# Plot some results
plotter = ar.Plotter('results.json')
plotter.plot_operation('heat_sink', 'Heat', lgd_pos='lower center',
bar_lw=0.5, ylabel='Thermal energy [MWh]')
plotter.plot_objective(lgd_pos='lower center')
```
The method *plot_operation* returns a mixed bar and line plot that visualizes
the operation of a component based on a selected commodity.

The method *plot_objective* returns a bar chart that summarizes the cost
contributions of each component to the overall objective function value
(net present value).
