The DLR Institute of Networked Energy Systems has developed the MTRESS tool that can be used to optimise energy supply systems for new and existing projects at any location. MTRESS facilitates the creation of energy system optimisation models for individual residential and commercial buildings, as well as for neighbourhoods and entire industrial properties. It enables users to include a wide range of influencing factors and energy options in the simulation and minimises the planning effort.
This is a generic model for community-based open source oemof.solph tool. MTRESS offers a variety of possible technology combinations for energy supply systems. It includes pre-built technologies that are commonly considered in energy systems, such as:
- Photovoltaic or wind power (as generic RenewableEnergySource)
- Grid Connection (Electricity, Heat and Gas)
- Heat Pumps
- Heat Exchangers
- Electrolysers (PEM, Alkaline, AEM)
- Fuel Cells (PEM, Alkaline, AEM)
- Compressors
- Combined Heat and Power (CHP) with various gas types and gas-mixtures (e.g., H2 + Natural Gas) as input fuels
- Storages (Battery, Heat Storage, Gas Storage (Hydrogen))
- Resistive Heater and Gas Boiler
It covers different sectors including Electricity, Heat and Gas (e.g., H2, Natural Gas, Biogas, etc.). It is tailored for optimising control strategies fulfilling fixed demand time series for electricity, heat, gas (including hydrogen), and domestic hot water using any selected combination of the implemented supply technologies.
MTRESS requires appropriately prepared initial data on the boundary conditions of the respective project. A wide range of data sources can be used, including historical energy consumption data for the project, but also higher-level data on the location, for example from climate models or the solar cadastre. Moreover, the forecasted demands and renewable generations could also be used for scheduling optimized operation for next days. It could be used for long-term planning and the assumptions about the development of costs and the CO2 impact of the future energy mix can also be incorporated into the modelling.
As an open-source model, MTRESS is available to users in a wide range of areas. It can be utilized for both research and commercial purposes. Researchers, utility owners, and policymakers can all benefit from this tool for energy system planning and operation. Applications are not just limited to municipal heating plans, home automation offerings, hydrogen infrastructure planning, and optimized operation of sector-coupled energy systems, but extend to any scenario requiring comprehensive energy optimization and management.
MTRESS depends on solph, which is automatically installed using pip
pip install mtressHowever, pip will not install a solver, to perform the actual optimisation. Please refer to the documentation of solph to learn how to install a solver.
The auto-generated documentation can be found on the GitLab pages.
The coverage report can be found on the GitLab pages as well.
Please refer to the examples folder in this repository to get acquainted with building and optimizing energy systems in MTRESS. These examples will help you understand the basics and guide you through the process before you start creating your own energy system.
