D-STATCOM in Electric Vehicle for Mitigating Power Quality issues in Grid

With the increased focus of the government on green mobility, we can expect the EV sector to flourish in India. Electric vehicles are becoming more efficient due to new battery technology and power electric converters. All most many electric vehicles are left idle in the parking lots and used for traveling only for a short time. Many grid services can be provided when electric vehicles are not used for transportation. It is possible to use EV as a storage device and also restore power to the grid, especially during peak hours. The ability to provide both harmonic and reactive power to the grid is possible by combining the DSTATCOM and Shunt Active Power filter. To control the amount of reactive power in a D-STATCOM and providing the amount of harmonic current to the grid is possible with the help of a controller. The main objectives of this paper are the development of three-phase grid-connected voltage source inverter control in dq frame. Development of charging/discharging control of EV battery connected to the DC link where EV battery will be represented using a constant DC voltage source. Modify control to incorporate D-STATCOM function and to develop the control to add active filter features to the converter. Here in this work, the EV connected D-STATCOM can improve the quality of the distorted grid. As a result, the devices connected to the grid will not be affected by the connection of a nonlinear load.
