Power Imbalance Analysis of Modular Multilevel Converter with Distributed Energy Systems
(2024)
The modular multilevel converter (MMC) can integrate distributed energy systems (DES), such as a battery energy storage system, to expand its functionalities and carry out multiple simultaneous tasks. However, a DES induces ...
Experimental evaluation of a CPT-based four-leg active power compensator for distributed generation
(2017-06-01)
Four-wire microgrids (MGs) and distribution systems are inherently unbalanced with the presence of negative and zero sequence components in voltages and currents. In small autonomous systems, the imbalance, in addition to ...
Cooperative control of power quality compensators in microgrids
(2021-04-01)
This paper proposes a consensus-based distributed control scheme, augmented by the conservative power theory for compensating imbalance and harmonics at the Common Connection Point (PCC). The consensus algorithm allows to ...
Compensação ativa paralela baseada na teoria de potência conservativa
(2012)
Trying to validate the Conservative Power Theory (CPT) for active filters controlling applications, this paper proposes a selective methodology for the generation of the active filter’s reference signals, which is based ...
Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmitters
(Springer Verlag Berlín, 2011-07-13)
The design of predistortion techniques for broadband multiple input multiple output-OFDM (MIMO-OFDM) systems raises several implementation challenges. First, the large bandwidth of the OFDM signal requires the introduction ...
Contributions to the mitigation of voltage imbalances in modern distribution networks with modular multilevel static synchronous compensators: modelling, control and energizing strategies

Sagittal balance: from theory to clinical practice
(British Editorial Soc Bone & Joint Surgery, England, 2021)
Adequate sagittal balance (SB) is essential to maintain an
upright, efficient, and painless posture. It has been shown
that sagittal profile alterations affect quality of life of patients
with a similar or even greater ...
