Development of sustainable energy indexes by the utilization of new indicators: A comparative study
(Elsevier Ltd, 2019-11-01)
Article
Open AccessDecision making to improve energy sustainability requires scientifically information based on sustainability. Since there are different sustainability targets and specific decision problems in this regard, hence to achieve ... -
Impedance measurement and detection frequency bandwidth, a valid island detection proposal for voltage controlled inverters
(Multidisciplinary Digital Publishing Institute, 2019-03-18)
Article
Open AccessAnti-islanding detection methods have been part of a secure operation for distributed energy resource inverters, avoiding the creation of non-intentional energization when the mains are lost. These detection mechanisms ... -

Measuring urban energy sustainability and its application to two Spanish cities: Malaga and Barcelona
(Elsevier, 2019-02-01)
Article
Restricted access - publisher's policyThe aim of the paper is to propose a methodology for evaluating the energy sustainability of a city based on the characterization of the energy end-use, energy systems and flows, as well as other intrinsically related ... -
Design methodology for a dc–dc power conversion system with EIS capability for battery packs
(2018-09-01)
Article
Restricted access - publisher's policyThis paper presents a design methodology for a dc-dc power conversion system (PCS) for battery packs. The methodology provides with an optimal design of the PCS and the associated inductive-capacitive filter interfacing ... -
OPEX of hybrid DC/AC power systems with large penetration of offshore wind taking into account spinning reserves
(2018-10-01)
Article
Restricted access - publisher's policyThis study presents a method to analyse the secure and optimal operation of transmission systems consisting of both HVDC (high-voltage direct current) and high-voltage alternating current interconnections under a scenario ... -
Control of the parallel operation of VSC-HVDC links connected to an offshore wind farm
(Institute of Electrical and Electronics Engineers (IEEE), 2019-02)
Article
Open AccessThis paper introduces the control of the parallel operation of two VSC-HVDC links interconnecting an offshore wind farm. The aim of the study is to propose and validate a control system that allows the parallel operation ... -
Impedance-based analysis of harmonic resonances in HVDC connected offshore wind power plants
(2019-01-01)
Article
Restricted access - publisher's policyDuring the last years, the installation and planning of offshore wind farms using HVDC-links to transmit power onshore has increased. After the first HVDC connected offshore wind power plant of this type had been commissioned, ... -
Technical and economic comparison of grid supportive vanadium redox flow batteries for primary control reserve and community electricity storage in Germany
(2019-01)
Article
Restricted access - publisher's policyPrimary control reserve and maximising self-consumption are currently two of the main applications for large-scale battery storage systems. Although being currently the most profitable application for large-scale batteries ...
