Stability and Control of Power Grids

Annual Review of Control, Robotics, and Autonomous Systems, 2022
Power grids are critical infrastructure in modern society, and there are well-established theories for the stability and control of traditional power grids under a centralized paradigm. Driven by environmental and sustainability concerns, power grids are undergoing an unprecedented transition, with much more flexibility as well as uncertainty brought ...

Multi-grid methods for power grid simulation

2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002
Power grids for sub-micron large integrated circuits are performance limiting factors due to the large power dissipated (e.g. 100 W at 1.8 V). The analysis of such power grids is important in order to predict and possibly improve the performance. Current classical analysis methods are falling behind as grids become ever larger.

Topology and power flows in power grids

2007 46th IEEE Conference on Decision and Control, 2007
In complex networks, such as electrical power grids, their properties depend on their interconnection topology. This paper studies the relationship between interconnection topology and power flows in power grids, and shows that by altering the interconnection topology one can alter the loadability of the grid. This has significance both in terms of the

Analysis and optimization of power grids

IEEE Design & Test of Computers, 2003
As the complexity of power and ground networks increases, methods for efficient analysis and aggressive optimization of these networks become essential. Here, the authors describe efficient hierarchical methods for analyzing distribution networks. To optimize the networks, the authors call for techniques that reduce noise on the power grid, including ...

On the Compressibility of Power Grid Models

IEEE Computer Society Annual Symposium on VLSI (ISVLSI '07), 2007
The simulation of power distribution networks is a difficult task owing to the large number of elements and ports in such circuits. In this work, the authors elaborate on the compressibility of power grid models. For this purpose, two main options are available, namely sparse or hierarchical model representations of such systems and equivalent reduced ...

Scrambling on electrical power grids

2008 IEEE International Conference on System of Systems Engineering, 2008
Deregulated, the U.S. electrical power grid system has shown the emergence of behaviors that include scrambling by buyers to purchase electricity and unexpected increasing costs of electricity to consumers. To infer those behaviors, in this paper, we adapt a theoretical framework, developed by Newman in his work on spread of epidemic disease on ...

On Robustness of Power Grids

2015
Current and future trends in environmental, economical, and human-caused factors (such as power demand growth, over-ageing of assets in power grids, and extreme weather conditions) challenge power grid robustness in the near future, necessitating research to better analyse and understand the notion of robustness in power grids, and ultimately to ...
