A Model for Planning Large Scale MV Networks considering Uncertainty in Reliability Modeling
Peco González, Jesús Pascual; Gómez San Román, Tomás (Sin editorial (Funchal, Portugal), 25/09/2000)This paper describes a model for planning large scale MV networks from scratch, that is, ignoring existing installations. The resultant ideal networks can be used by the regulator as a benchmark to set the remuneration of ... -
A Monte Carlo approach for assessment of investments deferral in radial distribution networks with distributed generation
Méndez Quezada, Víctor Hugo; Rivier Abbad, Juan Martín; Fuente León, José Ignacio de la; Gómez San Román, Tomás; Arcéluz Ogando, José; Marín, J.; Madurga, A. (Sin editorial (Bolonia, Italia), 23/06/2003)Distributed Generation (DG) is located in distribution networks near to consumers or even in the consumers side of the meter. Therefore, net demand to be supplied from transmission and distribution can decrease postponing ... -
A practical approach to solve power system constraints with application to the Spanish electricity market
Lobato Miguélez, Enrique; Rouco Rodríguez, Luis; Gómez San Román, Tomás; Echavarren Cerezo, Francisco; Navarrete Fernández, María Isabel; Casanova Lafarga, Rosa; López Camino, Gerardo (01/11/2004)The solution of power system constraints is an important issue that has to be addressed to achieve a fair operation of a competitive electricity market. In the Spanish electricity market, the System Operator (SO) is in ... -
A probabilistic model for power quality regulation based on Yardstick competition
López Sánchez, José María; Gómez San Román, Tomás (Sin editorial (Sevilla, España), 24/06/2002)The regulation of the electricity distribution utilities has evolved to a scenario based on competition and cost-effectiveness. This cost reduction may affect the quality performance. A quality regulatory proposal based ... -
A reactive power capacity market using annual auctions
Frías Marín, Pablo; Gómez San Román, Tomás; Soler Soneira, David (01/08/2008)This paper presents a new approach to design reactive power capacity markets. Under this approach annual auctions to procure reactive power capacity are conducted by the system operator. Two products are defined, reactive ... -
A reference network model for large-scale distribution planning with automatic street map generation
Mateo Domingo, Carlos; Gómez San Román, Tomás; Sánchez Miralles, Alvaro; Peco González, Jesús Pascual; Candela Martínez, Antonio (01/02/2011)A Reference Network Model (RNM) is a large-scale distribution planning tool that can help regulators to estimate efficient costs in the context of incentive regulation applied to distribution companies. This paper presents ... -
A review of cross-sector decarbonisation potentials in the European energy intensive industry
Gerres, Timo; Chaves Ávila, José Pablo; Linares Llamas, Pedro; Gómez San Román, TomásThe energy intensive industry (EII) is responsible for two-third of industrial carbon dioxide emissions in the EU. It has been recognised by both public and private stakeholders that a far-reaching transformation of these ... -
