A variable no-load voltage scheme for improving energy efficiency in DC- electrified mass transit systems
(Sin editorial (Colorado Springs, Estados Unidos de América), 2014-04-04)Railway mass transit systems like subways play a fundamental role in the concept of sustainable cities. In these systems, the amount of passengers strongly fluctuates along the day. Hence, in order to provide a proper ... -
Implications from changing the priority dispatch for intermittent energy sources to a market based approach: application to the Spanish case
(European Wind Energy Association (Bruselas, Bélgica), 2015-10-22)This paper discusses the market designs that impact intermittent energy sources (IES) curtailment, such as negative prices, the priority dispatch rule for IES and compensation for IES curtailment. It also describes the ... -
Computing leastcore allocations for firm-energy rights: a mixed integer programming procedure
(Institute of Electrical and Electronics Engineers Power and Energy Society (Boston, Estados Unidos de América), 2016-11-14)The Firm energy of generation plants is a critical component in some electricity markets. It is usually calculated by the regulator and sets a cap to the amount a plant can trade in capacity markets (or auctions), in order ... -
