In this paper , the authors introduced the basic concept and analysis tools of complex network theory to provide a deeper analysis of integrated energy systems (IES) and proposed the measures to optimize the reliability of the IES.Abstract:
As integrated energy systems (IES) continue to undergo development and advancement, the degree of coupling between subsystems and their complexity are also on the rise, posing a challenge for the reliability assessment of such systems. The conventional method is unable to explain the interaction between subsystems as well as system-level phenomena. The complex network theory is needed to provide a deeper analysis. Firstly, this paper introduces the basic concept and analysis tools of complex network theory. Secondly, the topological network model and the identification indexes of weak links for the IES are summarized as the basis for reliability assessment. Then, the reliability assessment indexes and assessment methods are sorted out for the IES based on the complex network theory; and further, the measures to optimize the reliability of the IES are put forward. Finally, from the perspective of complex network theory, directions for future research on the reliability assessment of IES are suggested. read more

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Emergence of Scaling in Random Networks
TL;DR: A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.

Energy hubs for the future
TL;DR: In this paper, the authors present a project named "Vision of Future Energy Networks", which aims at a greenfield approach for future energy systems, defined energy hubs and the conception of combined interconnector devices represent key approaches towards a multicarrier greenfield layout.

Recognition and Vulnerability Analysis of Key Nodes in Power Grid Based on Complex Network Centrality
TL;DR: Simulation results of IEEE 30-bus and IEEE 57-bus test cases show that the key nodes can be effectively identified with high electrical centrality and resultant cascading failures that eventually lead to a severe decrease in net-ability, verifying the correctness and effectiveness of the analysis.

Reliability modeling of multi-carrier energy systems
Gaudenz Koeppel,Göran Andersson +1 more
TL;DR: In this paper, a model for analyzing and calculating expected reliability of supply and expected energy not supplied in such multi-carrier energy systems is presented, which can be used to identify the benefit and sensitivity of certain conversions as well as their limits in terms of reliability improvements.
