Introduction
POMMES itself is a cosmos consisting of a dispatch model (stored in this repository and described here), a data preparation routine and an investment model for the German wholesale power market. The model was originally developed by a group of researchers and students at the chair of Energy and Resources Management of TU Berlin and is now maintained by a group of alumni and open for other contributions.
If you are interested in the data preparation routines used or investment modeling, please find more information here:

pommesdata: A full-featured transparent data preparation routine from raw data to POMMES model inputs
pommesinvest: A multi-period integrated investment and dispatch model for the German power sector (upcoming).

Purpose and model characterization
The dispatch variant of the power market model POMMES pommesdispatch enables the user to simulate the dispatch of backup power plants, storages as well as demand response units for the Federal Republic of Germany for an arbitrary year or timeframe between 2017 and 2030. The dispatch of renewable power plants is exogeneously determined by normalized infeed time series and capacity values. The models' overall goal is to minimize power system costs occuring from wholesale markets whereby no network constraints are considered except for the existing bidding zone configuration used for modeling electricity exchange. Thus, the model purpose is to simulate dispatch decisions and the resulting day-ahed market prices. A brief categorization of the model is given in the following table. An extensive categorization can be found in the model documentation.

Purpose
- simulation of power plant dispatch and day-ahead prices for DE (scenario analysis)


Spatial coverage
- Germany (DE-LU) + electrical neighbours (NTC approach)


Time horizon
- usually 1 year in hourly resolution


Technologies
- conventional power plants, storages, demand response (optimized) - renewable generators (fixed) - demand: exogenous time series


Data sources
- input data not shipped out, but can be obtained from pommesdata; OPSD, BNetzA, ENTSO-E, others


Implementation
- graph representation & linear optimization: oemof.solph / pyomo - data management: python / .csv



Mathematical and technical implementation
The models' underlying mathematical method is a linear programming approach, seeking to minimize overall
power system costs under constraints such as satisfying power demand at all times and not violating power generation
capacity or storage limits. Thus, binary variables such as units' status, startups and shutdowns are not accounted for.
The model builds on the framework oemof.solph which allows modeling
energy systems in a graph-based representation with the underlying mathematical constraints and objective function
terms implemented in pyomo. Some of the required oemof.solph featuresm - such as demand response modeling - have been provided by the POMMES main developers which are also active in the
oemof community. Users not familiar with oemof.solph may find further information in the
oemof.solph documentation.
Documentation
An extensive documentation of pommesdispatch can be found on readthedocs. It contains a user's guide, a model categorization, some energy economic and technical background information, a complete model formulation as well as documentation of the model functions and classes.
Installation
To set up pommesdispatch, set up a virtual environment (e.g. using conda) or add the required packages to your python installation. Additionally, you have to install a solver in order to solve the mathematical optimization problem.
Setting up pommesdispatch
pommesdispatch is hosted on PyPI.
To install it, please use the following command
pip install pommesdispatch

If you want to contribute as a developer, you fist have to
fork
it and then clone the repository, in order to copy the files locally by typing
git clone https://github.com/your-github-username/pommesdispatch.git

After cloning the repository, you have to install the required dependencies.
Make sure you have conda installed as a package manager.
If not, you can download it here.
Open a command shell and navigate to the folder
where you copied the environment to.
Use the following command to install dependencies
conda env create -f environment.yml

Activate your environment by typing
conda activate pommes_dispatch

Installing a solver
In order to solve a pommesdispatch model instance, you need a solver installed. Please see oemof.solph's information on solvers. As a default, gurobi is used for pommesdispatch models. It is a commercial solver, but provides academic licenses, though, if this applies to you. Elsewhise, we recommend to use CBC as the solver oemof recommends. To test your solver and oemof.solph installation, again see information from oemof.solph.
