Direct Methods for Transient Stability Assessment in Power Systems Comprising Controilable Series Devices

IEEE Power Engineering Review, 2002
In this paper, new energy functions that incorporate the action of controllable series devices (CSDs) are presented. They make it possible for the direct method to acquire the critical clearing time (CCT) of a single machine-infinite bus (SMIB) power system and the certain series flexible AC transmission systems (FACTS) devices directly.

In chemico assessment of potential sensitizers: Stability and direct peptide reactivity of 24 fragrance ingredients

Journal of Applied Toxicology, 2018
AbstractTwenty‐four pure fragrance ingredients of concern as potential skin sensitizers were previously subjected to degradation studies and evaluated using the high throughput with dansyl cysteamine (HTS‐DCYA) method. The experimental results showed that two‐thirds of the 24 fragrance ingredients underwent chemical degradation.

A Comparative Analysis of Decision Trees, Support Vector Machines and Artificial Neural Networks for On-line Transient Stability Assessment

2018 International Conference on Smart Energy Systems and Technologies (SEST), 2018
Transient instability is considered the most severe form of instability in power systems with grave socioeconomic repercussions if not prevented. Conventional methods, such as time domain simulations and direct methods impose limitations to fast on-line ...

Methods for Dynamic Stability Assessment

EPE, 2019
The paper deals with dynamic stability assessment. It analyses application of two approaches for the transient (rotor angle) stability calculations. It compares results of the conventional time domain simulation tool with simplified direct methods.

A Hybrid Analysis Approach for Transient Stability Assessment in Power Systems

2019 IEEE Milan PowerTech, 2019
The computational complexity involved in time-domain simulations, commonly used for analyzing transient stability in power systems, usually limits system studies to a few scenarios during the planning process.

A simple direct method for fast transient stability assessment of large power systems

IEEE Transactions on Power Systems, 1988
A method for online transient stability assessment of large power systems is proposed. It consists of: replacing the multimachine system by a two-machine dynamic equivalent, further amenable to a one-machine-infinite-bus system; reducing the stability problem to a sole algebraic equation, devised from the equal area criterion, or equivalently from the ...

Immobility, stability and ineffectiveness: Assessing the impact of direct election of the Israeli prime minister

The Journal of Legislative Studies, 1999
The Israeli parliamentary system has recently undergone radical structural changes due to the introduction of direct election of the Prime Minister. This paper sets out, first, to describe briefly the reform as a consequence of particular political developments of the Israeli system.

Assessing colour stability of direct printed and thermoformed aligners: An in vitro study on aesthetics longevity

International Orthodontics
To evaluate and compare the colour stability of direct-printed and thermoformed clear aligners after exposure to common staining agents.Clear aligners fabricated using two direct-printed resins, TC85 and TA28 (Graphy Inc., Seoul, Republic of Korea), and one thermoformed aligner, Erkodur (Erkodent, Germany), were tested for colour stability in coffee ...
