Optimal under voltage load shedding based on voltage stability index [PDF]
This paper presents a methodology for under voltage load shedding using a metaheuristic optimization technique and a stability criterion. Two strategies are proposed to find the minimal size and location of load to shed for the recovery of normal ...

Proposal of indexes for fast voltage stability evaluation of ac/dc transmission systems
This paper develops voltage stability analysis of ac/dc systems using static and modal indexes. New indexes treatment is proposed to provide more information on requirements for specific network strengths in terms of voltage stability constituting a means to prevent potential issues of high voltage dc transmission system (HVdc), connected to weak ac ...

Fast Load Voltage Stability Index constrained PMU Placement for Complete Observability
This paper proposes a Fast Load Voltage Stability Index (FLVSI) constrained Binary Integer Programming (BIP) method for Phasor Measurement Unit placement at optimal locations in network to obtain complete observability. Every load bus of network is considered to sort out weak load bus from proposed FLVSI approach.

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 ...
