“…A vulnerable communication system may cause abnormal operation of power grids, and even cascading failure [149,150]. Therefore, advanced data routing and switching algorithms are required for a reliable operation [151]. Attacks against intelligent protection devices, which is normally performed through the SCADA systems, can also severely disrupt the operation of power grid [107,152].…”

Power grids are cyber-physical systems and can be modelled as network systems where individual units (generators, busbars and loads) are interconnected through physical and cyber links. Network components (nodes/edges) may undergo intentional and/or random failures. In catastrophic cases, a failure initiating from a small set of these components can quickly propagate through the whole network, leading to a cascade of failures that might force a deep whole-grid blackout. Often network components have different vitality and protecting some is more critical than others. This manuscript aims to provide a focused overview of modelling power grids as complex networks and their resilience and reliability analysis. We also perform a critical review of vitality metrics and their precision in power grid resilience analysis. The review is accompanied by some simulations on benchmark and real power grids to show the applicability of these concepts in studying resilience.

“…These methods improve the feeders' reliability because in the case of fault occurrences, the utilities can restore power to some of its nodes with the use of switches, by trying to isolate the fault area and restore power to the greatest number of customers as possible. Some methods for optimizing the distribution networks regarding its switches positioning for this purpose have been proposed, such as (Chen et al 2006;Sohn et al 2006;Chen et al 2006;Moradi and Fotuhi-Firuzabad 2008;Tippachon and Rerkpreedapong 2009;de Souza et al 2015;Alam et al 2016;López et al 2016;Ray et al 2016;Popović et al 2017;Girón et al 2018;Rodrigues et al 2019;Vaz et al 2019;Seta et al 2020): simulated annealing, binary programming, classic programming, genetic algorithms, immune system, particle swarm, ant colony and path relinking. It is noted that these works tend to the use of heuristic methods to solve the problem more efficiently, and that the feeder's models are based on graphs, with nodes representing customers.…”

This paper presents a method for improving indices and costs associated with reliability in radial distribution systems through switch placement using genetic algorithms. On this paper, the switch allocation problem will be solved with a method that allows novelties that can improve the quality of the solutions obtained. First, the possibility of switch allocation on both sides of each section of a feeder is proposed. Second, a method to quantify the non-supplied energy in terms of dollars per kWh of interruption is expanded, allowing a versatile way to simulate cases in which individual customers have different economic impacts when in situation of interrupted power delivery. The proposed algorithm is also versatile when additional restrictions are applied, such as fixing the number of switches or imposing SAIDI limits. Optimal switch locations are defined to improve restoration and reduce costs associated with reliability. Simulations in test and real feeders are performed, and the presented results show significant improvements.

Under the new situation of large power grids, security and stability control systems and their communication channels are facing new changes and new requirements. The article proposes a smart grid dispatching control system multi-channel information intelligent comparison method, through the network monitoring method to obtain the main plant station information interactive communication message, using the intelligent comparison algorithm to compare remote signalling, telemetry, sequence of events (SOE), Communication protocol parameters such as remote control and remote adjustment are compared, and alarm events are output in time according to the comparison results. By combining the principle of the stability control device and the principle of communication self-healing, the influence of the stability control channel communication self-healing ability on the operation of the stability control device is analysed, and the influence of whether self-healing is adopted in operation is analysed. Based on the comparison, it is concluded that the communication channel of the regional network stability control system should use self-healing method.
