Analysing the Voltage Sensitivity in the Distribution Grid in Terms of Charging and Discharging of Electric Vehicle

Electric vehicle (EV) grid integration at a large scale is highly reliant on power costs, energy storage systems and renewable energy sources. This study employs an effective charge flow analysis method from a system for energy management to charge and discharge electric vehicles (EVs) in line with user needs. It consists of a regulated operating technique that utilizes the EV’s state of charge (SOC). The operation is primarily centered on two modalities, each of which completes the mission through EV SOC early detection. When EV charging and discharge may happen whenever during the day. The suggested method is put into practice and created in OpenDSS and Matlab to test the outcomes in various situations. This paper is proposed that the state of charge (SOC) of an electric vehicle (EV) when it is incorporated into a grid is determined using a control approach proposed in this research as an efficient way to charge and discharge EVs in a distribution system. In the first case, the EV’s SOC is determined by the controlling method system, and if it is within a certain range, the operation is started normally. In the second scenario, the user is free to choose a charging or discharging mode after the system reaches the predetermined limit. In addition, if VPP is unable to meet EV demand while charging during additional peak hours, the other mode will be engaged to do so and ensure appropriate functioning.
