This paper presents an overview of the different methodologies and mathematical optimization models developed in the framework of the EU-funded project SiNGULAR towards the optimal exploitation and efficient short-term operation of RES production in insular electricity networks. Specifically,...

This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES...

This paper presents a fuzzy set-based approach to the evaluation of information technology (IT) projects. We assume a multi-criteria decision-making framework, where sets of general and domain-specific criteria are used to judge the relative performance of alternative technologies. The...

In this paper we investigate the application of a methodology based on fuzzy-sets theory to the selection of an optimal portfolio of Greek government bonds. Investors’ goals for the different bond market scenarios are formulated in fuzzy qualitative terms, while a model of fuzzy mathematical...

We investigate the application of cointegration techniques in designing trading portfolios that outperform a market benchmark. Of particular interest is the situation of enhanced indexation with incomplete portfolios, that is, by imposing a limit on the maximum number of assets included in the...

In this paper, we explore two strategies for reducing the cash flow uncertainty of wind power traders ascribed to variable weather conditions. The first strategy is based on the idea of aggregating the output of geographically-dispersed generating units. The second strategy employs financial...

We assess the risk inherent in wind turbine investments that rely on a power market in order to determine the selling price of generated power. Using scenario analysis, we calculate various indexes that attempt to highlight different aspects of the market risk to which the energy producer is...
