 Abstract:
 ... Stringent grid codes imposed by transmission system operators (TSOs) have led wind turbine manufacturers to overdesign their products. As an individual power generator, each single wind turbine has to meet those regulations. However, in a “farm” like configuration, a different approach can be taken. This paper describes how renewable energy generator units can be simplified in order to bring manuf ...

 Abstract:
 ... In this paper we propose an evolutionary imperfect information game approach to analyzing bidding strategies in electricity markets with priceelastic demand. In previous research, opponent generation companies’ (GENCOs’) bidding strategies were assumed to be fixed or subject to a fixed probability distribution. In contrast, the adaptive and learning agents in the presented model can dynamically u ...

 Abstract:
 ... In developing countries, the exploitation of renewable sources is an opportunity to increase the number of people who have simple access to electricity and to water. Among other technologies, standalone photovoltaic pumping systems are often installed in remote areas where the grid is not available: they are used for irrigation and/or other local water needs and can supply also electricity to sma ...

 Abstract:
 ... Accurate modeling of heat transfer in the ground and inside the borehole is crucial to correctly size and assess performance of ground coupled heat pump systems. The model proposed here uses a hybrid approach combining two techniques. First, the rapid transient behavior inside the borehole is handled numerically with a fine grid in combination with a model size reduction technique to reduce comput ...
