Research on the three-phase load imbalance control of the active distribution network based on the distributed power flow controller

Frontiers in Energy Research
In the background of the global commitment to low-carbon renewable energy transformation, new energy sources such as distributed wind–solar storage and charging and single-phase loads, such as electric vehicles, are connected to the distribution network.

A three-phase power flow algorithm for distribution system power flow based on loop-analysis method

International Journal of Electrical Power & Energy Systems, 2008
Based on loop-analysis method, a theoretical formulation of the forward/backward sweep with compensation power flow method is presented. The reason, why the convergence of this widely used method deteriorates when the network becomes more meshed, is also well analyzed. Subsequently, a novel solution of unbalanced three-phase power systems based on loop-

A high power density single flow zinc-nickel battery with three-dimensional porous negative electrode [PDF]

, 2013
Low power density (operated current density) is one critical obstacle to the development of single flow zinc nickel batteries (ZNBs). Three-dimensional porous nickel foams (NFs) are first introduced to ZNBs to improve power density.

Power flow control in single-phase and three-phase grid-connected inverters using LMI, state-feedback linearization and D-stability [PDF]

, 2013
This paper proposes a methodology for the active and reactive power flow controls, applied at singlephase and three-phase inverters operating in grid-connected mode at low voltage. The converter's control technique is based on Linear Matrix Inequalities (

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
