In this paper we compare development trends, economics and financial risks of alternative large-scale solar power generation technologies (parabolic trough, solar tower, and three different photovoltaic technologies). In particular, a number of European countries, Algeria and the US promote...

Fuzzy sets theory is proposed as an alternative to the probabilistic approach for assessing portfolios of power plants, in order to capture the complex reality of decision-making processes. This paper presents different fuzzy portfolio selection models, where the rate of returns as well as the...

This study is based on the recent development of the European energy environment, which experiences a transition from being dominated by conventional energy generation into an increased penetration of renewable energy sources. Today's system operators offer a set of ancillary services, such as...

In this paper, the cooperation between Transmission System Operator (TSO) and Distribution System Operator (DSO) for power balancing of the transmission system is analyzed, whereby an exemplary grid situation is simulated. Based on the model, an optimization problem is formulated for the...

The ongoing European Union sustainable energy transition has a disruptive potential regarding the role of infrastructure and utilities in the electricity sector. The increased spread of digital technologies, renewable energy sources, and prosumers calls for a swift and well-guided adaptation of...

This paper studies the role of flexibility sources in the European electricity market, using a system dynamics model that includes various socio-technical factors, and a novel flexibility scoring concept. The learning rate impact of a new technology (gas-CCS) on the system’s flexibility is...

We develop a model of the European electricity market that allows analyzing the impact of consumers' price sensitivity, defined as the willingness to change energy providers, on equilibrium prices. The model is parameterized with publicly available data on total demand, marginal costs and...

Today's European utilities not only focus on electricity supply, but also offer exchange-traded “structured products” or portfolio management for unbundling financial and physical risk positions. Many utilities are only able to provide these services inside of their home markets, but in the...

In this paper, we investigate existing and possible future power generation capacities in Switzerland from a risk-return perspective, using the Mean-Variance Portfolio Theory of Markowitz (1952). The study covers power generation technologies currently in operation, such as nuclear power,...
