This article presents our view of why machine learning (ML) has not been able to find its way commercial products in the field protection. All methods we have reviewed literature essentially propose some ML-based technique replace a legacy protection scheme. The results are substantiated by training and testing ML models through simulated data. Legacy methods, on other hand, developed using mat...

The purpose of this paper is to analyze the supply chain resilience of Electric Power industry in Iran using fuzzy approach. The research is based on a survey of 23 experienced managers and experts in electricity industry having MA, MS or PhD degrees in Management, Electrical Power and Industry Engineering. Questionnaire data was used to assess the resilience status of Electric Power Industry i...

Abstract: Due to the energy savings and environmental protection they provide, plug-in electric vehicles (PEVs) are increasing in number quickly. Rapid development of PEVs brings new opportunities and challenges to the electricity distribution network’s dispatching. A high number of uncoordinated charging PEVs has significant negative impacts on the secure and economic operation of a distributi...
