“…With the increase of these electric fields in the presence of the air voids in the structure of the solid insulation layer, the solid insulation material will be exposed to the formation of the conductive cracks. These formed cracks resemble the shape of tree branches as a realistic embodiment of the electrical treeing phenomenon (ETP) [1][2][3][4].…”

“…As the non-uniform electric fields play a vital role in the ET inception and growth, the researchers seek seriously to the accurate calculation and distribution of these fields. They realised the complexity of the calculation of these fields by using the traditional methods so the numerical methods are the best approaches to be used [1,2,[13][14][15][16].…”

In this research, digital image processing method (DIPM) is used as an innovative approach to predict precisely the shape of electrical tree (ET) in cross-linked polyethylene (XLPE) power cables in the presence of air voids based on the field calculation using finite-element method (FEM). With the help of DIPM, two case studies are held to detect the accurate parameters of either the first initiated major branch or the tips of the major branches of ET. A hyperbolic needle-to-plane simulation model is proposed to illustrate the ET inception and propagation stages. The non-uniform electric fields thatare accompanied with the electrical treeing phenomenon are calculated using FEM as one of the most effective numerical methods to deal with non-uniform shapes. The predicted shapes of ET initiation and growth are provided in an innovative manner with the implemented hybrid connection between FEM and DIPM for the two proposed case studies. Direction branching approach and deviation angle branching approach are provided in this work to predict the shape and the direction of ET branched voids. The validity of the proposed model is assessed with the help of available previous experimental and simulation data.

“…The complete study of High Voltage (HV) and Extra High Voltage (EHV) complicated dangerous issues or phenomena in the generation, transmission and distribution systems is nowadays considered as an open challenge for researchers to either discover more hidden secrets or improve the methodologies to enhance the features of the power system networks in the presence of these harmful phenomena [1][2][3][4][5][6][7]. One of the most effective and common studies that are related to these HV and EHV phenomena is the accurate distribution of electric and magnetic fields and their calculation methodologies that affect and control directly the severity degree of these issues on the quality and service continuity of the different power system networks [8].…”

“…Due to the heat treatments and sudden cooling processes, The solid insulation is extremely exposed to the formation of air voids in the manufacturing. The presence of both air voids of the solid dielectric around the conducting wire and the initiated conducting protrusions through the conductor under abnormal operational modes will lead to the excessive generation of the nonuniform electric fields and the initiation or propagation of Electrical Tree (ET) [1][2][3][4]. It is necessary to show that the term Electrical Treeing is associated with the theoretical concept of ETP unlike the term Electrical Tree that is associated with the actual configurable representation of ETP so, it is commonly said that ET is the realistic embodiment of ETP .…”

This paper investigates the effect of the voltage variations and the change of solid insulation material on the initiation and propagation of Electrical Tree (ET) through solid dielectrics based on the application of Finite Element Method (FEM) approach using the environmental domain of [COMSOL Multiphysics ] program as an innovative way to be used in the complicated study of Electrical Treeing Phenomenon (ETP). This research provides an innovative solution to suppress the initiation point of ET and suppress its growth rates using a composite solid insulation material of Poly-Vinyl Chloride (PVC) and Cross-Linked Polyethylene (XLPE) regardless to the mechanical features of this composition. In this research, the study cases are conducted for High Voltage (HV) and Extra High Voltage (EHV) power system networks as the effect of ETP is to be observed clearly. The simulation model is used in this research to imitate the proposed hyperbolic needleplane system. Case studies are compared between each others to validate the results

In recent decades, the operational impact of Artificial Intelligence (AI) strategies is massively dominating the scientific arena of improving the operation of energy systems and their hybrid integrations. Comprehensively, this paper highlights the firm methodological link of AI strategies with the different defined categories of numerical methods in hypothetically simulating the complex integrated energy systems especially the integration of Renewable Energy Sources (RES). The conducted studies in this paper are related to the bifurcations of the applied numerical simulation methodologies for efficient energy systems and the practical implementations of the optimal operated energy systems considering the integration scenarios of these methodologies with AI strategies. Furthermore, this research reviews innovatively several case studies and practical examples to emphasize the effective contributions of AI strategies in enhancing the computational analysis of numerical simulation methods forming a smart approach for assessing experimental studies that are associated with energy systems. Finally, this paper deeply discusses the concept of integration either in the hybrid controlling strategies combining AI with numerical simulation methods or in combining different energy systems in one hybrid model for reliable operation considering the complexity level.
