Photovoltaic energy has been consolidated as one of the largest sources of renewable energy. Moreover, there is continuous worldwide growth in installed capacity. However, the inherent variability and uncertainty of these power systems are its main inconveniences. It causes undesirable effects on the distribution power grids and prevents it from participating in the electricity market as a manageable...
The paper presents the preliminary design and modelling of a point absorber wave energy converter consisting of a floating buoy connected to a tubular linear generator fixed at the seabed. The behaviour of the device is described by the equation of motion of a single body system restricted to vertical motion. The model of the coupled buoy-generator system is used to simulate the behaviour of the wave...
The start-up of anaerobic digestion processes is a complex problem, which determines the entire evolution of the system. In spite of its importance, this issue has not received so far a significant attention. This paper presents two simple startup strategies for an anaerobic digestion process, which have been developed based on the system dynamics. Both strategies consists of switching the dilution...
Cordoba is an inland province of southern Spain. This paper presents the quantity of power that will be necessary to install for covering the electrical consumption of Cordoba's population. Multicriteria has been the followed method with selection of criteria and options for the new and renewable energy technologies assessment based on the analysis and synthesis of parameters under the information...
Defining performance models associated with the application structure has been proven a useful strategy for implementing dynamic tuning tools. However, for extending this strategy to more complex applications (those composed by different structures) it must integrate a policy for the distribution of the resources among the different application components. Consequently, we propose to take advantage...
The aim of the paper is to study the optimal participation of wind energy in adjustment markets in order to increase the wind producer revenues, through a stochastic optimization process, which considers the uncertainty of the random variables involved, namely short-term wind power prediction, intraday price prediction and imbalance price. A new modeling of the behavior of up and down imbalance prices...
