The Global Energy System Model (GENeSYS-MOD) is an open-source energy system model, originally based on the Open-Source Energy Modeling System (OSeMOSYS) framework. While still part of the OSeMOSYS family of models, various aspects have been redesigned, expanded, or added. GENeSYS-MOD is a linear program, minimizing total system costs. Energy demands are exogenously predefined and the model needs to provide the necessary capacities to meet them. The modeling framework is very flexible in its use cases. Based on research question and input data, calculations can be done from a household-basis to a global aggregation of regions. In essence, GENeSYS-MOD can be

The peer-to-peer electricity trading model FRESH:COM developed by TU Wien is part of the case study “Behavior of communities of actors” within the H2020 project openENTRANCE. The model was transformed to an open-source model during the project. It is now publicly available on GitHub at github.com/tperger/FRESH-COM implemented in Python. The linear optimization model perfectly allocates prosumers’ renewable electricity generation from PV systems supported by battery energy storage systems (BESSs) among the actors of the community, considering each actor’s willingness-to-pay for avoiding emissions and for purchasing PV electricity generated by the community. The prosumers become active participants in decentralized energy markets,

The GUSTO model is an open-source model (OSM) optimizing the energy technology investment (portfolio decision optimization) and the technology dispatch on a local level. It is an extension of the existing OSM urbs. The expansion of the model’s framework includes additional features and functionalities. Hence, the model is tailor-made for analyzing local energy systems such as neighborhoods and energy communities. See the model application in the publications https://doi.org/10.1016/j.apenergy.2020.116166 and https://doi.org/10.3390/en14020305. The first one includes a detailed description of the model’s extension. The extended model is a mixed-integer linear program (MILP) and provides the following objective functions: (i) minimizing total costs of

The Open Generation and Transmission Operation and Expansion Planning Model with RES and ESS (openTEPES) determines the investment plans of new facilities (generators, ESS and lines) to supply the forecasted demand at minimum cost. Tactical planning is concerned with time horizons of 10-20 years. Its objective is to evaluate the future generation, storage and network needs. The main results are the guidelines for the future structure of the generation and transmission systems. The openTEPES model is a decision support system aimed at defining the generation and transmission expansion plan of a large-scale electric system at a tactical level. This plan

Integrate is an optimization model for planning of local energy systems where different energy carriers and technologies are considered simultaneously. The model gives the user a graphical overview of a given energy system (e.g. municipality, city, suburb) with respect to costs, environmental consequences and use of local energy resources. The current version can optimize the construction of infrastructure for most relevant energy carriers; electricity, district heating, cooling, gas, waste and biomass, including conversions between these. It is not limited to continuous transport like lines, cables and pipes, but can also include discrete transport by ship, road or rail. The main
