Open AccessMachine learning algorithms and the increasing availability of data have radically changed the way how decisions are made in today’s Industry. A wide range of algorithms are being used to monitor industrial processes and ... -
Improving voltage imbalance in inverter-based islanded microgrids during line-to-line short circuits
(2023-04-20)
Article
Open AccessLine-to-line short circuits are the transient disturbances that cause the highest currents as well as the largest voltage imbalances in inverter-based microgrids. This paper presents a control scheme for grid-forming ... -
Economic and regulatory uncertainty in renewable energy system design: a review
(2023-01-12)
Article
Open AccessRenewable energy is increasingly mobilizing more investment around the globe. However, there has been little attention to evaluating economic and regulatory (E&R) uncertainties, despite their enormous impact on the project ... -
Maximum current injection method for grid-forming inverters in an islanded microgrid subject to short circuits
(2023-02-03)
Article
Open AccessIn islanded microgrids, when a short circuit or a sudden overload occurs, it provokes an abrupt increment in the currents supplied by the generation nodes, which feed the load collaboratively. This is particularly challenging ... -
An experimental approach for secondary consensus control tuning for inverter-based islanded microgrids
(2023-01-03)
Article
Open AccessA microgrid is a group of interconnected loads and distributed energy resources that can fill the gap between the dependence on a bulk power grid and the transition to renewable energies. The islanded mode presents itself ... -
Collaborative voltage unbalance compensation in islanded AC microgrids with grid-forming inverters
(Institute of Electrical and Electronics Engineers (IEEE), 2022-04-25)
Article
Open AccessThe presence of unbalanced loads in power systems creates voltage imbalances that perturb the operation of sensitive loads like induction motors, power electronics converters and adjustable speed drives. This paper presents ... -
Methodology for obtaining simplified models for the long-term energy management of renewable assets under a high degree of uncertainty
(Elsevier, 2022-11)
Article
Open AccessThis paper addresses the attainment of a methodology aimed at obtaining simplified models embedding the regulatory constraints imposed by the country-specific remuneration mechanisms in the energy management system of long ... -
Decoupled simultaneous complex power sharing and voltage regulation in islanded AC microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2023-04)
Article
Restricted access - publisher's policyIn islanded AC microgrids, when multiple voltage source inverters (VSIs) operate in parallel, it is challenging to simultaneously obtain both accurate complex (active and reactive) power sharing and voltage regulation (in ... -
Constrained predictive control based on a large-signal model for a three-phase inverter connected to a microgrid
(Institute of Electrical and Electronics Engineers (IEEE), 2022-07-21)
Article
Open AccessSmall-signal models are the mostly used to model and design in inverter-dominated microgrids. Conversely, this paper proposes a large-signal model for grid-forming inverters connected to a microgrid based on the active and ... -

(Elsevier, 2022-03)
Article
Restricted access - publisher's policyThis paper seeks to quantify the effects of the increasing penetration level of renewable distributed generation and energy storage systems on the regulated electricity market over time. More specifically, the emphasis is ... -
Control scheme for negative-sequence voltage compensation and current sharing in inverter-based grid-connected microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2022-01-06)
Article
Restricted access - publisher's policyThis paper presents a control scheme that simultaneously solves the problems of negative-sequence voltage compensation and negative-sequence current sharing in grid-connected microgrids using grid-feeding inverters. ...
