Three-stage method for intentional controlled islanding of power systems
Journal of Modern Power Systems and Clean Energy, 2017 Power system controlled islanding is an emergency control to stop the propagation of disturbances and to avoid blackouts. This paper presents a three-stage method for intentional controlled islanding of power systems.

Some voltage graph-based LDPC tailbiting codes with large girth [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 The relation between the parity-check matrices of quasi-cyclic (QC) low-density parity-check (LDPC) codes and the biadjacency matrices of bipartite graphs supports searching for powerful LDPC block codes. Algorithms for searching iteratively for LDPC block codes with large girth are presented and constructions based on Steiner Triple Systems and short ...

A graph search algorithm: Optimal placement of passive harmonic filters in a power system [PDF]
Journal of Artificial Intelligence and Data Mining, 2015 The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers ...

Discrete Mathematics, 1974 AbstractA possible way to obtain a complicated graph imbedding in a surface is to derive it as a covering of a simpler imbedding by assigning “voltages” to the edges of the simpler imbedding. Although this new method is but the dual of the current graph construction,it has independent importance in practical applications, illustrated here by a ...

Conservation laws and open systems on higher-dimensional networks [PDF]
, 2008 We discuss a framework for defining physical open systems on higher-dimensional complexes. We start with the formalization of the dynamics of open electrical circuits and the Kirchhoff behavior of the underlying open graph or 1-complex.

Multi-objective partition planning for multi-infeed HVDC system
Global Energy Interconnection, 2021 The close proximity and the necessity of coordination between multiple high-voltage direct currents (HVDCs) raise the issue of grid partitioning in multi-infeed HVDC systems. A multi-objective partition strategy is proposed in this paper.
