Modeling Flexibility in Energy Systems - A Scenario-Based Comparison of Power Sector Model

Model-based scenario analyses of future energy systems often come to deviating results and conclusions when different models are used. This may be caused by heterogeneous input data and by inherent differences in model formulations. The representation of technologies for the conversion, storage, use, and transport of energy is usually stylized in comprehensive system models in order to limit the size ...

Comparison of Power Sector Models by Analyzing the Impact of Modeling Features on Optimal Capacity Expansion

The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. In a model comparison, we examine the optimal expansion of such technologies with six capacity expansion power system models. The technologies under investigation include base- and peak-load power plants, electricity storage, and transmission. We define four highly simplified ...

DIETERpy: A Python framework for the Dispatch and Investment Evaluation Tool with Endogenous Renewables

DIETER is an open-source power sector model designed to analyze future settings with very high sharesof variable renewable energy sources. It minimizes overall system costs, including fixed and variablecosts of various generation, flexibility and sector coupling options. Here we introduce DIETERpy thatbuilds on the existing model version, written in the General Algebraic Modeling System (GAMS),and ...

Optimal Supply Chains and Power Sector Benefits of Green Hydrogen

Green hydrogen can help to decarbonize parts of the transportation sector, but its power sectorinteractions are not well understood so far. It may contribute to integrating variable renewable energysources if production is sufficiently flexible in time. Using an open-source co-optimization model of thepower sector and four options for supplying hydrogen at German filling stations, we find a trade-offbetween ...

Democratic Quality and Nuclear Power: Reviewing the Global Determinants for the Introduction of Nuclear Energy in 166 Countries

This paper analyzes the nature of democratic development in a nation on the process of introducing nuclear power over the period 1960 - 2017 for an unbalanced panel of 166 countries. Given the involved political process of introducing nuclear power and its political importance, as well as proposals to construct new nuclear reactors in currently about 30 countries, this question is both of historic ...

Nuclear Power as a System Good: Organizational Models for Production along the Value-Added Chain

Due to its technical complexity, the co-production of electricity generation and nuclear weapons, and its high fixed costs, nuclear power is a particularly complex commodity, which poses unusual challenges for state economic (or industrial, defense, innovation etc.) policy. As in other sectors, the question arises here, too, of an adequate division of private and public responsibilities, in other words ...

Prosumage of Solar Electricity: Tariff Design, Capacity Investments, and Power Sector Effects

We analyze how tariff design incentivizes households to invest in residential photovoltaic and battery storage systems, and explore selected electricity sector effects. To this end, we develop an open-source electricity sector model that explicitly features prosumage agents and apply it to German 2030 scenarios. Results show that lower feed-in tariffs substantially reduce investments in residential ...

Techno-Economic Criteria to Evaluate Power Flow Allocation Schemes

We develop novel quantitative techno-economic evaluation criteria for power flow allocation schemes. Such schemes assign which nodes are responsible for which proportion of power flows on a line in a meshed electricity transmission network. As this allocation is, as such, indeterminate, the literature has proposed a number of dedicated schemes. To better understand the implications of applying different ...
