The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

Standard methods for optimal allocation of shares in a financial portfolio are determined by second-order conditions which are very sensitive to outliers. The well-known Markowitz approach, which is based on the input of a mean vector and a covariance matrix, seems to provide questionable...

In this paper a robust approach to modelling electricity spot prices is introduced. Differently from what has been recently done in the literature on electricity price forecasting, where the attention has been mainly drawn by the prediction of spikes, the focus of this contribution is on the...

The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

Ensuring the security of stable, efficient, and reliable energy supplies has intensified the Interconnections among energy markets. Imbalances between supply and demand due to operational failures, congestions and other sources of risk faced by these connections can lead to a system that is...

Despite the high upfront financial costs associated with the existing technologies for energy storage they have become more appealing in recent years in response to the increasing importance of non-dispatchable sources of generation in the energy systems of developed countries. One of the...
