Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)
This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ...
STATCOM prototype in voltage control mode to assess its behavior in electric power networks
(2013)
The aim of this work is to present a Static Synchronous Compensator laboratory prototype for node voltage regulation at the connection point under load changes. Proportional Integral control systems are used to regulate ...

An Improved Parameterization Technique for the Continuation Power Flow
(IEEE, 2010-01-01)
Continuation methods have been long used in P-V curve tracing due to their efficiency in the resolution of ill-conditioned cases, with close to singular Jacobian matrices, such as the maximum loading point of power systems. ...
Singularities Analysis of the Jacobian Matrix Modified in the Continuation Power Flow: Performance Evaluation
(2017-11-01)
In the literature, a study to analyze stability and voltage instability is related to the P-V curve (power versus voltage magnitude) and the maximum loading point (MLP) (point on the curve that separates the stable operation ...
Modeling of open-circuit voltage of phenyl-C61-butyric acid methyl ester-like based bulk-heterojunction solar cells
(2015-12-01)
New materials are currently being sought for use in active layers of bulk-heterojunction organic solar cells, and computational modeling plays an important role in this search. Although open circuit voltage (Voc) is one ...
AI automates substation control
(2002-01-01)
An overview is given on the possibility of controlling the status of circuit breakers (CB) in a substations with the use of a knowledge base that relates some of the operation magnitudes, mixing status variables with time ...
