This study presents a novel micro-grid protection scheme based on Hilbert–Huang transform (HHT) and machine learning techniques. Initialisation of the proposed approach is done by extracting three-phase current signals at targeted buses different feeders. The obtained non-stationary are passed through empirical mode decomposition method to extract intrinsic functions (IMFs). In next step using HHT selected IMFs component, needful differential features computed. extracted further used as an...
The shift of transportation technology from internal combustion engine (ICE) based vehicles to electric (EVs) in recent times due their lower emissions, fuel costs, and greater efficiency has brought EV the forefront power distribution systems ability interact with grid through vehicle-to-grid (V2G) infrastructure. adoption EVs presents an ideal use-case scenario acting as dispatch, storage, ancillary service-providing units. This aspect can be utilized more current smart (SG) by...
With the remarkable growth and implementation of communication technology, sensors, measurement equipment in Smart Grid (SG) environment, demand side management (DSM) response (DRs) can be easily implementable residential energy systems integrated with renewable sources (RES).
