Novel power electronic device for power angle stability control

open access: yesThe Journal of Engineering, 2022
This letter proposes a novel phase sequence exchange (PSE) device. When the generator loses synchronization and the power angle gradually increases, the primary side of the contact line is disconnected and quickly connected in a staggered phase using the

Voltage Stability Analysis of Power System with Photovoltaic Power Plant

open access: yesJurnal Nasional Teknik Elektro, 2023
Photovoltaic power plants usually do not provide reactive power output; hence the application of large photovoltaics in power systems will decrease the voltage stability level of the power system. Capacitor banks can provide reactive power to compensate

Asymmetry underlies stability in power grids

open access: yesNature Communications, 2021
Behavioral homogeneity is often critical for the functioning of network systems of interacting entities. In power grids, whose stable operation requires generator frequencies to be synchronized—and thus homogeneous—across the network, previous work ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
