Combining economic and fluid dynamic models to determine the optimal spacing in very large wind farms
Stevens, Richard J.A.M.; Hobbs, Benjamin F.; Ramos Galán, Andrés; Meneveau, Charles (2017-03-01)Wind turbine spacing is an important design parameter for wind farms. Placing turbines too close together reduces their power extraction because of wake effects and increases maintenance costs because of unsteady loading. ... -
Economic inefficiencies of cost-based electricity market designs
Muñoz Espinoza, Francisco David; Wogrin, Sonja; Oren, Shmuel S.; Hobbs, Benjamin F. (2018-05-01)Some restructured power systems rely on audited cost information instead of competitive bids for the dispatch and pricing of electricity in real time, particularly in hydro systems in Latin America. Audited costs are also ... -
Energy storage solutions to decarbonize electricity through enhanced capacity expansion modelling
Levin, Todd; Bistline, John; Sioshansi, Ramteen; Cole, Wesley J.; Kwon, Jonghwan; Burger, Scott; Crabtree, George W.; Jenkins, Jesse D.; O’Neil, Rebecca; Korpas, Magnus; Wogrin, Sonja; Hobbs, Benjamin F.; Rosner, Robert; Srinivasan, Venkat; Botterud, Audun (2023-11-01)To meet ambitious global decarbonization goals, electricity system planning and operations will change fundamentally. With increasing reliance on variable renewable energy resources, energy storage is likely to play a ... -
Integrated offshore wind farm design: optimizing micro-siting and cable layout simultaneously
Marge, Thomas; Lumbreras Sancho, Sara; Ramos Galán, Andrés; Hobbs, Benjamin F. (2019-12-01)Electrical layout and turbine placement are key design decisions in offshore wind farm projects. Increased turbine spacing minimizes the energy losses caused by wake interactions between turbines but requires costlier ... -
Network-constrained Cournot models of liberalized electricity markets: the devil is in the details
Barquín Gil, Julián; Boots, Maroeska G.; Ehrenmann, Andreas; Hobbs, Benjamin F.; Rijkers, Fieke A.M.; Vázquez Martínez, Miguel (2005-05-01)Numerical models of transmission-constrained electricity markets are used to inform regulatory decisions. How robust are their results? Three research groups used the same data set for the northwest Europe power market as ... -
Open versus closed loop capacity equilibria in electricity markets under perfect and oligopolistic competition
Wogrin, Sonja; Hobbs, Benjamin F.; Ralph, Daniel; Centeno Hernáez, Efraim; Barquín Gil, Julián (2013-09-01)We consider two game-theoretic models of the generation capacity expansion problem in liberalized electricity markets. The first is an open loop equilibrium model, where generation companies simultaneously choose capacities ... -
Open versus closed loop capacity equilibria in electricity markets under perfect and oligopolistic competition - The case of asymmetric electricity generation firms
Wogrin, Sonja; Hobbs, Benjamin F.; Ralph, Daniel; Centeno Gonzalez, Jóse; Barquín Gil, JuliánIn this paper we consider cost asymmetry of generation companies when comparing open and closed loop equilibrium models of the generation capacity expansion problem in liberalized electricity markets. We show that under ... -
Renewable electric energy integration: Quantifying the value of design of markets for international transmission capacity
Barquín Gil, Julián; Bialek, Janusz W.; Boyd, Rodney; Dent, Chris J.; Echavarren Cerezo, Francisco; Grau, Thilo; von Hirschhausen, C.; Hobbs, Benjamin F.; et al., ? (2013-11-01)Integrating large quantities of variable renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable ...
