STUDY OF BATTERY ENERGY MANAGEMENT FOR EV UNDER CONDITION HYBRID BESS AND V2G IN MICROGRID

Abstract

Abstract  This paper discusses the installation of electric vehicles (EVs) integrated with battery energy storage systems (BESS) in the setting of transferring energy from vehicle-to-grid (V2G) to a microgrid distribution system, employing the IEEE 13 bus standard. The EVs have a power rating of 4.8 kilowatts (kW), while the BESS has a power rating of 500 kW. The overall design connects These systems to the three-phase bus, utilizing the daily load profile. Bus settings are available on 632, 633, 634, 671, 675, and 680 buses. The power flow computation in the Open Distribution System Simulation (OpenDSS) program is utilized by the simulation. Results of a research investigation comparing the implementation of EVs and BESS within microgrid systems. The study's findings were compared to both the regular system and the system that was implemented. The highest and minimum values of the per-unit system exhibit equality. The aggregate power distribution for active and reactive power exhibits a negligible disparity of less than 1 %. Regarding the power loss value in both active systems, namely free and reactive, a marginal difference of less than 1 % exists. The presence of the backup power supply does not have any impact on the primary testing system utilized in the experiment.    Keywords : Electric vehicles, Battery energy storage systems, V2G
