The research used a method for hybrid installing the system in a microgrid distribution system. The IEEE 13 bus standard was applied to test the installation system with a computer program. The program was tested with the Open electric power distribution (OpenDSS) program, a simulator for electric distribution. It was simulated continuously loading within 24 hours of installation of EV charging station, PV and ESS at 680 bus as it is the last bus of the microgrid system. OpenDSS was developed to implement hybrid under the condition that the PV size is 0.48 kW, 2000 kW, and the ESS size is 500 kW, 3000 kVAR. The EV battery with a power of 4.8 kW. The active power under the condition adds hybrid systems under the condition PV-EV, PV-ESS, and PV-ESS-EV. The results of the study on the installation of hybrid systems in the microgrid system. The comparison between the standard and the installed system showed that the maximum and minimum values of the percentage system were almost the same for the sum of both active and reactive power supply. There are similar values with a percentage difference of less than 1 %, while the power loss in both active and reactive systems have a percentage difference that is less than 1 %. The installed hybrid systems do not affect the tested system in the microgrid systems. Keywords—hybrid PV and ESS, EV, EV charging station I. INTRODUCTION Electricity demand has seen a significant increase in demand due to economic growth and technological advancement in sectors such as industry, communications, transportation, and transportation in electric vehicles (EV). It causes an inevitable increase in energy consumption activities. General electricity from fossil fuels such as coal, oil, and large amounts of natural gas. Renewable energy using reduces the capacity use of fossil fuels and promotes the use of clean energy in the industry. The EV use of power from solar energy hybrid stored in batteries to support the power of charging electric vehicles during peak periods can High Voltage Transformer Grid Commercial Load Residential Load EVs PV Systems AC DC Inverter EVs EVs Inverter Battery Energy Storage Systems AC DC EVs EVs Industrial Load Fig. 1. The concept of hybrid PV and BES for EV charging station reduce the cost of using electricity during peak demand [1] periods. In particular, solar PV technology is a renewable energy source that can be part of distribution generators (DGs) [2]. The PV can be used in energy management to charging stations and inject power from DGs into the grid. The demand for energy [3] from PV is timing for power to connect to the grid but battery energy storage is used to keep power in charging stations. The concept of hybrid PV and BES for EV charging stations [4] is shown in Fig. 1. In the microgrid system, there are loads used for industrial load, commercial load, residential load, and other loads [5]. The
