Abstract

The surge in the use of fossil fuels has led to the alarming depletion of these resources. To save the non-renewable resources with a greener environment, battery electric vehicles (BEV) have been invented. However, the primary charging source of BEV is through the conventional grid. This does not fulfill the overall objective of having a BEV, as presently, electricity supplied to the grid is generated by nonrenewable sources. In this work, a standalone Solar PV array system has been developed to effectively charge the BEV battery and supply the excess electricity generated to an IEEE 5 Bus system. The power flow control logic has been developed to realize switching between various modes. The PID controller is used to eliminate the transients occurring in inverter output. The MATLAB simulations show that excellent transient overvoltage protection has been achieved with the effective utilization of surplus electricity by the proposed control scheme.
