Physically Meaningful Grid Analytics on Voltage Measurements using Graph Spectra

2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020
Time synchronized measurements of voltage magnitudes or phasors are increasingly common in electrical networks. Voltage measurement statistics are informative of the underlying network structure or topology making them useful for grid monitoring. However, this connection is poorly understood and many proposed voltage analytics are purely heuristic.

A voltage scheduling heuristic for real-time task graphs

2003 International Conference on Dependable Systems and Networks, 2003. Proceedings., 2004
Energy constrained complex real-time systems are becoming increasingly important in defense, space, and consumer applications. In this paper, we present a sensible heuristic to address the problem of energy-efficient voltage scheduling of a hard real-time task graph with precedence constraints for a multi-processor environment.

Graph partitioning of power network for emergency voltage control

2013 9th Asian Control Conference (ASCC), 2013
This paper presents an electrical network graph partitioning technique that divides a power network into zones. The idea of partitioning is to prevent the propagation of disturbances between zones and avoid cascading events in response to disturbances.

Voltage graph embeddings and the associated block designs

Journal of Graph Theory, 1979
AbstractThe voltage graph construction of Gross (orientable case) and Stahl as well as Gross and Tucker (nonorientable case) is extended to the case where the base graph is embedded in a pseudosurface or a generalized pseudosurface. This theory is then applied to produce triangular embeddings of K4(n); they in turn yield an infinite class of partially ...

FDCCII Based Voltage Mode Filter Design Using Signal Flow Graphs

2007 IEEE 15th Signal Processing and Communications Applications, 2007
In this work, a new fully differential current conveyor - FDCCII based voltage mode active-RC filter is designed. For this purpose, a new general synthesis method is proposed by using signal flow graphs. Using this method, a second order filter obtaining low-pass, band-pass and high-pass filter characteristics is designed. Passive element sensitivities

Online Dynamic Voltage Scaling using Task Graph Mapping Analysis for Multiprocessors

20th International Conference on VLSI Design held jointly with 6th International Conference on Embedded Systems (VLSID'07), 2007
This paper presents a run-time slack distribution strategy for precedence constrained task graphs mapped on to a voltage scalable multiprocessor platform. Online dynamic voltage scaling techniques use the slack formed due to early finish of tasks and lower the supply voltage suitably so that energy reduction is achieved while meeting the worst-case ...

Reinforcement of power distribution network against voltage sags using graph theory

2009 IEEE Student Conference on Research and Development (SCOReD), 2009
This paper presents the application of graph theory to reinforce a power distribution network against voltage sags. Voltage sag is considered as one of the main power quality problems which may cause sensitive equipment to malfunction and process interruption.

Employing Differential Voltage Current Conveyor in graph coloring applications

2010 International Conference on Power, Control and Embedded Systems, 2010
A non-linear feedback neural network for solving graph coloring problem is presented. The proposed circuit employs non-linear feedback, in the form of unipolar comparators realized using DVCCs and diodes, to introduce transcendental terms in the energy function ensuring fast convergence to the solution.
