In this paper, an improved modular multilevel converter (MMC) control strategy based on one-cycle control (OCC) is proposed. With the introduction of OCC, the stability, rapidity and disturbance rejection of MMC is greatly improved. Based on the volt-second equilibrium, the control is distributed to every single submodule (SM). For further stability, an unbalanced OCC strategy is designed based...

This paper proposes a control methodology for compensation of grid voltage unbalances using a new scheme of doubly fed induction generator (DFIG) based on a series grid side converter (SGSC), the seriesDFIG scheme. In such DFIG scheme, the grid side converter (GSC), which is usually connected in parallel to the machine stator, is replaced by the SGSC, connected in series with the machine stator...

User experience is essential for humancomputer dialogue systems. However, it is impractical to ask users to provide explicit feedbacks when the agents’ responses displease them. Therefore, in this paper, we explore to predict users’ imminent dissatisfactions caused by intelligent agents by analysing the existing utterances in the dialogue sessions. To our knowledge, this is the first work focus...

Abstract A new inter-cluster DC capacitor voltage balancing scheme for a delta connected modular multilevel cascaded converter (MMCC)-based static synchronous compensator (STATCOM) is presented. detailed power flow analysis of applying negative sequence current (NSC) and zero-sequence (ZSC) injection methods in addressing the issue imbalance under unbalance grid carried out. control proposed wh...

The current paper provides modelling guidelines for nonlinear analysis and fragility assessment of corrosion-damaged reinforced concrete (RC) structures. A systematic guideline is proposed to model the adverse impact corrosion on mechanical properties steel materials including negative inelastic buckling low-cycle fatigue (LCF) degradation reinforcing bars. fibre-based technique capable simulat...

Many of the stochastic neuron models employed in the neurobiological literature generate renewal point processes, i.e., successive intervals between spikes are statistically uncorrelated. Recently, however, much experimental evidence for positive and negative correlations in the interspike interval (ISI) sequence of real neurons has been accumulated. It has been shown that these correlations ca...

In business and sports, teams often experience periods of positive and negative momentum while pursuing their goals. However, researchers have not yet been able to provide insights into how psychological and behavioral states actually change during positive and negative team momentum. In the current study we aimed to provide these insights by introducing an experimental dynamical research desig...
