The Dispatch and Investment Evaluation Tool with Endogenous Renewables (DIETER) has been developed in the research project StoRES to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model determines cost-minimizing combinations of power generation, demand-side management, and storage capacities and their respective dispatch. DIETER thus captures multiple system values of power storage related to arbitrage, firm capacity, and reserves.

The electricity sector model family ELMOD includes a variety of spatial optimization models with detailed representations of the European electricity sector including the generation portfolio and the physical transmission network. ELMOD models apply a bottom-up approach which combines economic and engineering features of the electricity sector. ELMOD models determine the cost-minimizing or welfare-maximizing dispatch taking into account flows in the high-voltage transmission network using a DC load flow approach as well as technical characteristics of generation units. ELMOD models allow addressing a variety of research questions concerning, e.g., market design, congestion management, and investments in electricity infrastructures. The development of ELMOD was initiated in 2006 by Florian Leuthold, Hannes Weigt, and Christian von Hirschhausen.
The initial ELMOD version and the dataset has been continuously extended, updated, and applied at DIW Berlin and TU Berlin. By now, four members of the ELMOD family have evolved:
ELMOD represents the European electricity system on a nodal level with an hourly time resolution.. The model comprises a detailed representation of the European transmission network and the spatial generation and load pattern.
The initial ELMOD formulation is documented and applied in Leuthold, F.U., Weigt, H., Hirschhausen, C. (2012): A Large-Scale Spatial Optimization Model of the European Electricity Market. In: Networks and Spatial Economics. 10, 1, pp. 75-107.
A detailed description of data and data sources for the European electricity system and the handling of data is provided in DIW Data Documentation 72 (PDF, 8.53 MB).

stELMOD is a stochastic optimization model to analyze the impact of uncertain wind generation on the day ahead and intraday electricity markets as well as network congestion management. After clearing of the daily day ahead and the subsequent hourly intraday markets, the final power plant dispatch is determined by the transmission system operator considering network congestion arising from previous market commitments. The consecutive clearing of the electricity markets is incorporated by a rolling planning procedure resembling the market process of most European markets.

dynELMOD is a multi-period investment model of the European electricity sector until 2050. The model optimizes the electricity generation, storage and network infrastructure investments by minimizing total system cost, given policy targets of constraints. Investments are determined in five or ten-year steps considering the hourly dispatch of existing and new built generation technologies. Interactions between countries through the interconnected transmission network are incorporated by using either a country-sharp power transfer distribution factor matrix (PTDF) based on the actual transmission network or using net transfer capacities (NTCs) based on commercial cross-border transactions.
The model is documented in the DIW Data Documentation 88 (PDF, 4.81 MB) by Clemens Gerbaulet and Casimir Lorenz.

Das Global Gas Model (GGM) wurde gemeinsam mit Prof. Ruud Egging, PhD von der NTNU entwickelt und wird mit ihm gemeinsam genutzt.
GGM ist ein Gleichgewichtsmodell des weltweiten Marktes für Erdgas (inkl. fossiles Erdgas, Schiefergas, LNG). Alle Länder mit nennenswerter Erdgasförderung, -verbrauch, sowie -transport sind Teil des Datensatzes. Je nach Datensatz werden bis zu 100 Knoten unterschieden.
Im Modell werden die verschiedenen Akteurstypen ("Spieler") im Erdgassektor unterschieden: Produzenten, Transporteure (Pipeline und LNG) sowie Speicher. Im Modellaufbau als Gleichgewichtsmodell werden deren jeweilige Gewinnoptimierungsprobleme und spezifische Kosten abgebildet und miteinander verbunden sowie gleichzeitig gelöst. Das Modell ist in GAMS programmiert.
Mit dem Global Gas Model werden regelmäßig Studien zum europäischen und globalen Erdgasmarkt durchgeführt. Hier eine Auswahl:
OILMOD is a numerical partial equilibrium model of the international crude oil market. The producer-focussed model allows to investigate the consequences of climate and market policies as well as different sector developments such as technical innovation. Crude oil exporting countries are modelled as profit-maximising suppliers in oligopolistic quantity competition. Different versions of the model feature refinery, node-to-node transportation, endogenous investments, and varying competition setups.
As the crude oil market is dominated by a small number of large producers as well as the presence of the Organisation of the Petroleum Exporting Countries (OPEC), the market can hardly be defined as competitive. Therefore, OILMOD allows for a flexible approach of modelling different (asymmetric) competition set-ups by using conjectural variation and an explicit formulation of multi-level frameworks, i.e. sequential decision-making in production quantities.
The model is formulated and solved as a mixed coplanarity problem (MCP) in the General Algebraic Modeling System (GAMS) using the solver PATH, using MS Excel for data processing and output reports. The multi-level formulation of OILMOD is formulated as a mixed-integer nonlinear problem (MINLP) and solved using BONMIN.

COALMOD-World is a model of the international steam coal market that can be readily used to explore implications of climate policies, but also to analyze market structure or to investigate issue of supply security. It features a detailed representation of both domestic and international steam coal supply, based on endogenously calculated Cost, Insurance, Fright (CIF) costs, and prices that take into account additional rents. It features endogenous investment into production, land transport, and export capacity, as well as an endogenous mechanism assessing production cost increase due to resource depletion.

An optimization model of CCTS infrastructure in Europe.
The energy system and resource market model "MultiMod" is a large-scale representation of the supply and demand of fossil fuels and renewable energy sources. It captures in a unified framework important energy market features such as endogenous substitution between fuels, infrastructure constraints and endogenous investment, as well as market power by producers of fossil fuels.
"This model was developed within the BMBF-project RESOURCES, in collaboration with NTNU Trondheim. It is updated in the EU Horizon 2020 project SET-Nav. The mathematical formulation of the MultiMod model is a dynamic Generalized Nash Equilibrium (GNE) derived from individual players' profit maximisation problems. The formulation is generic and flexible, so that the supply chain of any number of fossil and renewable fuels can be modelled. The framework includes seasonality and allows for a detailed infrastructure representation and a comprehensive transformation sector (power generation, refinery sector). Investment in infrastructure (transportation, seasonal storage, transformation) is determined endogenously in the model according to the respective player’s inter-temporal optimisation problem. Furthermore, substitution between different energy carriers on the final demand side is endogenous. By formulating the model as an equilibrium problem with different player types based on non-cooperative game theory, the model can incorporate Cournot market power by individual suppliers as well as distinct discount rates by various players concerning their investment. The current framework is an open-loop perfect foresight model. A stochastic version of the model is under development at NTNU Trondheim. This will allow for consideration of uncertainty and distinct risk profiles for individual players along the supply chain, including investment by consumers in energy efficiency.
The model is formulated and solved as a Mixed Complementarity Problem (MCP) and implemented in GAMS, using MS Access and MS Excel for data processing and output reports. Initially, a database representing the global energy system was compiled and used for scenario analysis (Huppmann & Egging, 2014). Other datasets or variations of the initial data base are have later been developed within specific research projects:
