IET Generation, Transmission & Distribution, 2022 The increasing use of distributed generation (DG) in power systems can result in frequent online voltage problems. In scenarios in which substantial DG prediction errors occur because of high DG accommodation levels, traditional technical solutions ...

Multiobjective Approach to Schedule DAG Tasks on Voltage Frequency Islands
IEEE Access, 2023 Scheduling a Directed Acyclic Graph (DAG) on voltage frequency islands involves dividing the available processing units into multiple islands with varying voltage and frequency levels and then mapping the tasks of the DAG to the islands while minimizing ...

Lifting Graph Automorphisms by Voltage Assignments
European Journal of Combinatorics, 2000 The authors provide the first systematic combinatorial treatment of the automorphism lifting problem in the context of graphs. They make consistent use of several new fundamental concepts: the action of the fundamental groupoid, the notion of a voltage space, various kinds of invariance of voltage spaces, and the geometry of the lifted actions by means

LDPC codes from voltage graphs
2008 IEEE International Symposium on Information Theory, 2008 Several well-known structure-based constructions of LDPC codes, for example codes based on permutation and circulant matrices and in particular, quasi-cyclic LDPC codes, can be interpreted via algebraic voltage assignments. We explain this connection and show how this idea from topological graph theory can be used to give simple proofs of many known ...
