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 ... -
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, Tomás (01/02/2019)The energy intensive industry (EII) is responsible for two-thirds 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 ... -
A review of power distribution test feeders in the United States and the need for synthetic representative networks
Postigo Marcos, Fernando Emilio; Mateo Domingo, Carlos; Gómez San Román, Tomás; Palmintier, Bryan; Hodge, Bri-Mathias; Krishnan, Venkat; Cuadra García, Fernando; Mather, Barry (18/11/2017)Under the increasing penetration of distributed energy resources and new smart network technologies, distribution utilities face new challenges and opportunities to ensure reliable operations, manage service quality, and ... -
A review on generation and transmission expansion co-planning models under a market environment
González Romero, Isaac Camilo; Wogrin, Sonja; Gómez San Román, TomásThis paper presents a review of the state of the art on the coordination of generation and transmission expansion planning. First, we present the different modelling approaches to represent transmission and generation ... -
A security-constrained decomposition approach to optimal reactive power planning
Gómez San Román, Tomás; Pérez Arriaga, José Ignacio; Lumbreras, J.; Parra, V.M. (01/08/1991)A two-level decomposition technique for VAr (voltampere reactive) sources planning in electric power systems is presented. Several operating conditions of the system (different base cases with associated contingencies) can ... -
A sensitivities computation method for reconfiguration of radial networks
González García, Alezeia; Echavarren Cerezo, Francisco; Rouco Rodríguez, Luis; Gómez San Román, Tomás (01/08/2012)Distribution networks are operated in a radial configuration, but their topology, especially in urban areas, is normally meshed in order to improve reliability of supply. This makes it possible to configure the network ... -
Accounting for network energy losses when computing distribution locational marginal prices in a large-scale power system: application to the Spanish case
Chaves Ávila, José Pablo; Gómez San Román, Tomás; Ramos Galán, Andrés; Castro Cerdas, Juan JoséThis paper presents a novel approach to compute an electric equivalent network representation that includes the main characteristics of electricity networks in a meaningful way, including relevant aspects that affect the ... -
