Dynamic Line Rating Models and Their Potential for a Cost-Effective Transition ...
Estanqueiro, Ana; Algarvio, Hugo; Couto, António; Michiorri, Andrea; Salas, Sergio; Pudjianto, Danny; Hagglund, Per; Dobschinski, Jan; Bolgaryn, RomanABSTRACT: Most transmission system operators (TSOs) currently use seasonally steady-state models considering limiting weather conditions that serve as reference to compute the transmission capacity of overhead power lines. The use of dynamic line rating (DLR) models can avoid the construction of new lines, market splitting, false congestions, and the degradation of lines in a cost-effective way. DLR can also be...
Strategies for Continuous Balancing in Future Power Systems with High Wind and ...
Nordström, Henrik; Söder, Lennart; Flynn, Damian; Matevosyan, Julia; Kiviluoma, Juha; Holttinen, Hannele; Vrana, Til Kristian; van der Welle, AdriaanABSTRACT: The use of wind power has grown strongly in recent years and is expected to continue to increase in the coming decades. Solar power is also expected to increase significantly. In a power system, a continuous balance is maintained between total production and demand. This balancing is currently mainly managed with conventional power plants, but with larger amounts of wind and solar power, other sources...
Design and operation of energy systems with large amounts of variable generatio...
Holttinen, Hannele; Kiviluoma, Juha; Helistö, Niina; Levy, Thomas; Menemenlis, Nickie; Jun, Liu; Cutululis, Nicolaos Antonio; Koivisto, MattiABSTRACT: This report summarises findings on wind integration from the 17 countries or sponsors participating in the International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 25 from 2006–2020. Both real experience and studies are reported. Many wind integration studies incorporate solar energy, and most of the results discussed here are valid for other variable renewables in addit...
Review of wind generation within adequacy calculations and capacity markets for...
Soder, Lennart; Tómasson, Egill; Estanqueiro, Ana; Flynn, Damian; Hodge, Bri-Mathias; Kiviluoma, Juha; Korpås, Magnus; Neau, Emmanuel; Couto, AntónioABSTRACT: The integration of renewable energy sources, including wind power, in the adequacy assessment of electricity generation capacity becomes increasingly important as renewable energy generation increases in volume and replaces conventional power plants. The contribution of wind power to cover the electricity demand is less certain than conventional power sources; therefore, the capacity value of wind pow...
