Barrier functions for design centering and security enhancement

چکیده
This paper does two things. First, it relates the notions of power system security to the concepts of design centering. A benefit is a family of metrics for measuring security. Such metrics are badly needed security is too ephemeral to lend itself readily to measurement. Second, the paper develops a method for solving centering problems and thereby, extremis ing the aforementioned security metrics. The method uses Barrier functions to translate centering problems Into unconstrained minimization problems. It appears to be simpler and more widely applicable than methods based on inscribing norm bodies in approximations to feasible regions." Snail test problems indicate that the Barrierfunction method has a performance edge over inscribed norm body methods. We expect, this edge to Increase with problem size.

Local Self-concordance of Barrier Functions Based on Kernel-functions
Many efficient interior-point methods (IPMs) are based on the use of a self-concordant barrier function for the domain of the problem that has to be solved. Recently, a wide class of new barrier functions has been introduced in which the functions are not self-concordant, but despite this fact give rise to efficient IPMs. Here, we introduce the notion of locally self-concordant barrier functio...
متن کاملOptimal placement of post-tensioned self-centering yielding braced systems for braced frame structures
The experience of past prominent earthquakes establishes the fact that the structure’s catastrophes and casualties can be dramatically decreased through the use of self-centering systems. A promising post-tensioned self-centering yielding braced system (PT-SCYBS) has been developed, comprising of two main components, including the post-tensioned wires, exhibiting the desirable self-centering pr...
متن کاملModeling of Dynamic Behavior and Estimation of Damage Incurred by Self-Centering Rocking Walls
Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...

Housing is viewed as a collection of characteristics that are used to satisfy goals, such as comfort and visual quality. Identifying the most important functions of facade results in improving quality. In this regard, the facade plays a crucial role in creating the borders of inner space in contact with its surroundings and can be considered as an interface. This study aimed to investigate and ...
متن کاملPost-Tensioned Steel Connections Self-Centering Behavior Using the Finite Element Method
Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...
