PI-based controller for low-power distributed inverters to maximise reactive current injection while avoiding over voltage during voltage sags
(2018-10-25)
Article
Accés obertIn the recently deregulated power system scenario, the growing number of distributed generation sources should be considered as an opportunity to improve stability and power quality along the grid. To make progress in this ... -
Local frequency restoration for droop-controlled parallel inverters in islanded microgrids
(2018-01-01)
Article
Accés obertIn islanded microgrids, voltage source inverters working in parallel are expected to provide regulation of the local frequency while granting active power sharing. This paper presents a local control approach at each ... -
Receding-horizon model predictive control for a three-phase VSI with an LCL filter
(Institute of Electrical and Electronics Engineers (IEEE), 2018-11-20)
Article
Accés obertThis paper presents a Continuous Control Set Model Predictive Control with receding horizon for a threephase voltage source inverter with LCL filter, using a reduced model of the converter. The main advantages of using ... -

(Institute of Electrical and Electronics Engineers (IEEE), 2018-01-23)
Article
Accés restringit per política de l'editorialTraditionally, the vector operation technique has been used to control three-phase converters using one cycle control. In this paper, a three-phase active power filter large-signal model with vector operation technique in ... -
Analysis of the effect of clock drifts on frequency regulation and power sharing in inverter-based islanded microgrids
(2018-02-12)
Article
Accés obertLocal hardware clocks in physically distributed computation devices hardly ever agree because clocks drift apart and the drift can be different for each device. This paper analyses the effect that local clock drifts have ... -
Performance comparison of grid-faulty control schemes for inverter-based industrial microgrids
(2017-12-11)
Article

Control strategy for distribution generation inverters to maximize the voltage support in the lowest phase during voltage sags
(Institute of Electrical and Electronics Engineers (IEEE), 2017-08-07)
Article
Accés obertIEEE Voltage sags are considered one of the worst perturbations in power systems. Distributed generation power facilities are allowed to disconnect from the grid during grid faults whenever the voltage is below a certain ... -
Assessing the 2014 retroactive regulatory framework applied to the concentrating solar power systems in Spain
(2018-02-15)
Article
Accés obertThe RD 413/2014 new economic and regulatory framework applied to the concentrating solar power plants (CSPP) in Spain has been here analysed and its new remuneration scheme has been formulated, becoming evident its high ... -
Analysis, design and implementation of a DC/DC boost resonant-inductor converter with sliding-mode control
(2018-03-20)
Article
Accés obertModern DC-DC resonant converters are normally build around a voltage-source series-resonant converter. This study aims to facilitate the practical use of current-source parallel-resonant converters due to their outstanding ... -
Positive and Negative Sequence Control Strategies to Maximize the Voltage Support in Resistive-Inductive Grids During Grid Faults
(2017-07-27)
Article
Accés obertGrid faults are one of the most severe perturbations in power systems. During these extreme disturbances, the reliability of the grid is compromised and the risk of a power outage is increased. To prevent this issue, ...
