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 paper aims to analyze what happens with renewable energy power plants, such as onshore wind, photovoltaics and biomass, when the public policy support based on the Renewable Energy Law expires. With its expiration the first renewable energy (and especially onshore wind) power plants will...

In this paper we start off by reviewing the literature on how to extend the mean-variance portfolio model to multi-stage portfolio problems. We then apply a multi-period portfolio selection model to power generation assets, which is based on a reallocation methodology with scenario tree. Two...

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...

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...
