Rodrigues Jacobi polynomial based control technique for on board EV charger in single phase power distribution system

Le résumé fourni par la source

The present research proposes a control technique for a bidirectional AC side converter that is based on the Rodrigues Jacobi Polynomial (RJP) algorithm. The bidirectional DC side converter, connected to the battery at the DC link of the AC-DC converter, will function as an on-board electric vehicle (EV) charger. In the proposed system, a bidirectional converter (AC-DC, DC-DC), nonlinear loads, and a single-phase grid are used to develop the model. The charging and discharging operations during the Grid to Vehicle (G2V) and Vehicle to Grid (V2G) modes of operation are illustrated and described in detail. The paper also examines the impact of harmonic distortion caused by nonlinear loads. The proposed system's performance is initially modelled and analyzed using Matlab/Simulink. In the laboratory, the prototype system is created for experimental verification. This work presents a detailed discussion of the performance in both steady state (SS) and dynamic state (DS) using the suggested control technique based on RJP. This study also compares the suggested algorithm's performance to that of algorithms based on Synchronous Reference Frame Theory (SRFT) and Laguerre polynomials (LP).
