Estado del arte modelo óptimo de operación posterior a ataques intencionales considerando conmutación de los sistemas de transmisión

La presente investigación está enfocada en la operación óptima posterior a ataques intencionales considerando conmutación de los sistemas de transmisión. Los modelos aplicables para este proceso se enfocan en la aplicación de métodos de optimización binivel que son capaces de analizar dos posibles escenarios con el fin de disminuir el tiempo de pérdida o salida de la demanda del sistema eléctrico. El principal objetivo de este trabajo está relacionado en mantener los requerimientos mínimos que permitan la operación del Sistema Eléctrico de Potencia para esto se realizará el planteamiento de ecuaciones que permita establecer los modelos matemáticos ante ataques intencionales el mismo deberá mantener el funcionamiento del Sistema Eléctrico y reaccionar ante contingencias a través de la Conmutación Óptima de Líneas de Transmisión.This research focuses on optimal post-intentional attack operation considering switching transmission systems.

The main objective of this work is related to maintaining the minimum requirements that allow the operation of the Electric Power System, for this the approach of equations will be carried out that allows establishing the mathematical models in the event of intentional attacks, it must maintain the operation of the Electric System and react in the event of contingencies through the Optimal Switching of Transmission Lines

Exploration of TPUs for AI Applications

Tensor Processing Units (TPUs) are specialized hardware accelerators for deep learning developed by Google. This paper explores the performance of TPU with a focus on AI and its implementation in edge computing. It first provides an overview of TPUs, specifically their design in relation to neural networks, their general architecture, compilation techniques and supporting frameworks. Furthermore, we provide a comparative analysis of Cloud and Edge TPU performance against other counterpart chip architectures. It is then discussed how TPUs can be used to speed up AI workloads. The results show that TPUs can provide significant performance improvements both in cloud and edge computing. Additionally, we address the need for further research for the deployment of more architectures in the Edge TPU, as well as the need for the development of more robust comparisons in edge computing.Comment: Research done by the Robotics & AI Club at IE Universit

Análisis bibliométrico de la planeación de expansión de los Sistemas Eléctricos de Potencia

This article presents a bibliometric analysis on the planning of the expansion of electric power systems, a topic of great importance due to the continuous growth of electricity demand. For this reason, electrical power systems must be designed and built to foresee future expansions through the entry of new generation plants, transmission lines and compensating equipment. For the development of this research, keywords that will help find articles on the same subject in Scopus and Web of Science databases will be taken into account.

Modelling Complex Dynamics and Distributed Generation of Knowledge with Bacterial-Based Algorithms

This study aimed to test that connected and heterogeneous societies with peer-to-peer (P2P) exchanges are more resilient than centralized and homogeneous ones. In agent-based modeling, agents with bounded rationality interact in a common environment guided by local rules, leading to Complex Adaptive Systems that are named 'artificial societies'. These simplified models of human societies grow from the bottom up in computational environments and can be used as a laboratory to test some hypotheses. We have demonstrated that in a model based on free interactions among autonomous agents, optimal results emerge by incrementing diversity and decentralization of communication structures, as much as in real societies Internet is leading to the emergence of improvements in collective intelligence. In order to achieve a real “Knowledge Society”, what we have named a “P2P Society”, it is necessary to increase decentralization and heterogeneity through information policies, distributed communication networks, open e-learning approaches and initiatives like public domain licenses, free software and open data

Decentralization and heterogeneity in complex adaptative systems

Following a bacterial-based modeling approach, the authors want to model and analyze the impact of both decentralization and heterogeneity on group behavior and collective learning. The paper aims to discuss these issues. Inspired by bacterial conjugation, the authors have defined an artificial society in which agents’ strategies adapt to changes in resources location, allowing migration, and survival in a dynamic sugarscape-like scenario. To study the impact of these variables the authors have simulated a scenario in which resources are limited and localized. The authors also have defined three constraints in genetic information processing (inhibition of plasmid conjugation, inhibition of plasmid reproduction and inhibition of plasmid mutation). The results affirmed the hypothesis that efficiency of group adaptation to dynamic environments is better when societies are varied and distributed than when they are homogeneous and centralized.The authors have demonstrated that in a model based on free interactions among autonomous agents, optimal results emerge by incrementing heterogeneity levels and decentralization of communication structures, leading to a global adaptation of the system. This organic approach to model peer-to-peer dynamics in complex adaptive systems (CAS) is what the authors have named “bacterial-based algorithms” because agents exchange strategic information in the same way that bacteria use conjugation and share genome

Alternative Under Frecuency Load Disconection Methodology Based on Semi-Adaptative Model

Stability analysis in electrical power systems is based on the study in dynamic state of the voltage and frequency, since at the moment that there is some contingency it fluctuates drastically due to the primary and secondary controls of the voltage and frequency to the power systems that act on the generators. In order to solve the possible stability problems that may arise in power systems, various techniques have been developed that act on the generating machines for their protection as well as on the loads for the power cut. The present investigation proposes an alternative methodology for load disconnection by low frequency as an option to save the power system from a possible blackout due to instability due to a fall in the frequency, managing to improve the results affected by other improved techniques, the frequency change range, frequency deviation and the effects of demand disconnection. The proposed methodology was tested in the IEEE 14 bus system
