A conjectural supply function equilibrium in energy and reserve for a weekly horizon
(Instituto Superior de Engenharia de Lisboa (Lisboa, Portugal), 20/05/2015)Despite the fact that reserves still have a small impact on the final electricity price, the rapid irruption of renewable and interruptible technologies has put in the spotlight the value of these services. It seems therefore ... -
A contingency analysis for managing the risk of water spillage or shortage in a mid-term hydro scheduling model
(Sin editorial (Estocolmo, Suecia), 2007-05-21)This paper proposes a methodology to determine secure operation policies of hydro systems through a contingency scenario analysis in order to prevent the risk of spillage or shortage due to inflows different to those of ... -

A dual band circularly polarized antenna based on a microstrip patch filled with left-handed structures
(Sin editorial (Edimburgo, Reino Unido), 11/11/2007)Microstrip patches filled with left-handed structures are proposed to obtain dual band circularly polarized antennas. The proposed antennas have two modes at different frequencies with similar characteristics to the ... -
A first year, VHDL based, digital electronics course
(IEEE Education Society; IEEE Computer Society; y ASEE Educational Research and Methods Division (Madrid, España), 2014-10-22)Most classical digital electronics textbooks have addressed the design with hardware description languages (HDL) as an addition to the traditional curricula. This is true, due that the design of digital circuits and the ... -
A flexible methodology to obtain a feasible thermal operation in the medium-term for multi-area power systems
(Institute of Electrical and Electronics Engineers Power and Energy Society; Universidad Pontificia C (Madrid, España), 2021-07-29)Currently, the modeling of electricity markets demands the representation of multi-area power systems with the greatest time detail. Many market players are taking investment positions to diversify the location of their ... -
A formulation for large-scale transmission expansion planning problem and a solution strategy
(IEEE Pes (Estocolmo, Suecia), 2013-05-27)The expected deployment of massive renewable energy sources (RES, mainly of wind and solar) at a continental or even intercontinental level creates very complex transmission expansion planning (TEP) problems. Both the size ... -
A fundamental study on the impact of HVDC lines on transient stability of power systems
(Eindhoven University of Technology (Eindhoven, España), 29/06/2015)An increasing number of HVDC lines are currently deployed all around the world. HVDC links are either based on line-commutated converters (LCC) or on voltage-source converters (VSC) technologies. This paper presents a ... -
