Analysis of the demand charge in DC railway systems and reduction of its economic impact with energy storage systems
Roch Dupré, David; López López, Álvaro Jesús; Rodríguez Pecharromán, Ramón; Cucala García, María Asunción; Fernández Cardador, Antonio (2017-12-01)In addition to energy consumption, DC railway operators must also pay for the demand charge. This term of the electricity bill has not been studied in detail in the literature and penalizes power peaks. The big fluctuations ... -
