Semiconductor fabs use up to 100 megawatt-hours of power each and every hour Semiconductor manufacturing facilities require a massive amount of energy to support their facilities and manufacturing processes. Large fabs can use as much as 100 megawatt-hours of power each hour – more than many oil refineries and automotive plants. Energy use will continue to increase with higher production ...
At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power grids with stochastic distributed generation, we study the effects of erratic ...
Vulnerability analysis is a key issue in power systems since power transmission grids play a crucial role as a critical infrastructure. The power grid structure (number of nodes and lines, their connections, and their physical properties and operational constraints) is one of the main factors to assure ...
Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man–made systems like power grids, gas and water networks and the internet, have been also included in this network framework, albeit sometimes ignoring the huge historical body of ...
Most of critical infrastructures (CIs) depend on the power system. The predictable onset of a microgeneration paradigm (many dispersed small generators of medium-low power) will considerably decrease network stability and thus increase risk of failures and other's infrastructures dependence. In order to study the ...
Cascading failures in electrical power networks often come with disastrous consequences. A variety of schemes for mitigating cascading failures exist, but the vast majority depend upon centralised control architectures. ...
Apart from this, we evaluate how the topological efficiency and vulnerability measures (clustering coefficient, information centrality, betweenness centrality) evolve in the course of time. The decisions regarding the power grid topology are influenced by many, very often contradictory factors, such as costs, the size of the covered area, demand, fault tolerance, reliability and ...
The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. ...
The objective of this research is to investigate innovative power distribution components based on micro-electromechanical systems technologies integrated with advanced optimisation methods to improve the performance of electric power distribution systems. ...
The Intelligent Power Router (IPR), a concept based on scalable coordination, is proposed to control the next generation power network. ...
Specifically, our approach places one autonomous software agents at each bus of a power network, each of which is tasked with solving the global control problem with limited data and communication. ...
This paper describes a large set of electricity data for the IEEE 24 bus system generated on a test bed that copies the cyber layer of the electricity infrastructure in some detail. This data has been filtered and corrupted with natural noise and a realistic set of failure-induced and attack-induced corruptions. One of the main applications of this data is the development of ...
