Holomorphic embedding method based Three-Phase power flow algorithm considering the sensitivity of the initial value

International Journal of Electrical Power & Energy Systems
The transmission network is generally considered as three-phase balanced, while the consideration of three-phase unbalance is mainly on distribution networks.

Grid-tie Three-phase Inverter With Active and Reactive Power Flow Control Capability

Eletrônica de Potência, 2014
This paper proposes a methodology for the active and reactive power flow control, applied to a low voltage grid-tie three-phase power inverter. The control technique is designed by means of feedback linearization and the pole placement is obtained using

Application of the SSA to the Optimal Phase-Swapping Problem in Three-Phase Asymmetric Networks

Revista UIS Ingenierías, 2023
This research addresses the optimal phase-balancing problem by applying a master-slave optimization methodology. The master stage defines the load connections per node using a discrete codification, while the slave stage evaluates each load ...

Three-phase distribution network fast-decoupled power flow solutions

International Journal of Electrical Power & Energy Systems, 2000
Abstract An efficient power flow solution is introduced in this paper. This solution is a current-injection based Newton–Raphson method in rectangular coordinates. The Jacobian matrix of the proposed method could be decoupled into two identical sub-Jacobian matrices. The G-matrix is used to execute load flow. The “Fast-Decoupled” idea is incorporated

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Improvements in Bidirectional Power-Flow Balancing and Electric Power Quality of a Microgrid with Unbalanced Distributed Generators and Loads by Using Shunt Compensators

Energies, 2018
Improper connections of unbalanced distributed generators (DGs) and loads in a three-phase microgrid cause unbalanced and bidirectional power flow problems. The unbalanced DGs and loads may also aggravate the electric power quality (EPQ), such as voltage

Effective theories of scattering with an attractive inverse-square potential and the three-body problem

, 2004
A distorted-wave version of the renormalisation group is applied to scattering by an inverse-square potential and to three-body systems. In attractive three-body systems, the short-distance wave function satisfies a Schroedinger equation with an ...

Bidirectional DC-DC-AC Three-phase Power Converter [PDF]

, 2013
poster abstractThis work proposes a dc-dc-ac three-phase converter in order to interface dc and ac variables allowing a bidirectional power flow. A comprehensive comparison between the proposed and conventional solutions will be addressed highlighting ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
