Efficient Simulation of Power Grids
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2010Modern deep sub-micron ultra-large scale integration designs with hundreds of millions of devices require huge grids for power distribution. Such grids, operating with decreasing power supply voltages, are a design limiting factor and accurate analysis of their behavior is of paramount importance as any voltage drops can seriously impact performance or

A Machine Learning Approach to Detection of Geomagnetically Induced Currents in Power Grids
IEEE transactions on industry applications, 2020Geomagnetically induced currents (GICs) in power grids are mainly caused by geomagnetic disturbances especially during solar storms. Such currents can potentially cause negative impacts on power grid equipment and even damage the power transformers ...

Simulation and analysis of cascading faults in hybrid AC/DC power grids
International Journal of Electrical Power & Energy Systems, 2020With the increasing use of DC transmission in existing AC networks, the possibility of AC and DC circuits running parallel to each other and sharing the same right-of-way or even the same tower is increasing.

The paper describes on-chip 3D power grid (PG) modeling for high performance CPU designs. We show that for high frequencies (above 1 GHz) it is necessary to use the full RLM PG model with extracted partial self and mutual conductors' inductances, rather than resistive R or RL models.

Proceedings of the 37th conference on Design automation - DAC '00, 2000
The decrease in feature size and added chip functionality in large sub-micron integrated circuits demand larger grids for power distribution. Since power grids are performance limiting factors [1, 2, 3], then their analysis is important in order to (1) predict the performance and (2) improve the performance if necessary. Thus, there is a clear need for

Fast Screening of Vulnerable Transmission Lines in Power Grids: A PageRank-Based Approach
IEEE Transactions on Smart Grid, 2019In power system operation, there are usually a few vulnerable lines (VLs) which are prone to exacerbate the propagation of cascading failures and lead to severe blackouts with high probability.
