Combination of Diesel Generator Set with Solar PV-Powered Battery Proposed EV Battery Exchange Charging System

Abstract

In this study, a EV charging station powered by the grid (CS), a diesel generating set with an energy storage system, a solar PV (Photovoltaic) array, and battery are used to enable continuous charging in connected to the grid, attached to a DG set, and islanded modes. With the help of a BES and solar photovoltaic array, the charging station is primarily used for charging EV batteries. In the event that the storage battery runs out or the solar array does not generate electricity, smart use of the charging station can utilize a DG (Diesel Generator) unit or the grid to provide electricity. The DG sets are designed so that they always operate at 80–85 percent loading in order to optimize fuel economy. As an additional benefit, the charging station utilizes a storage battery to keep the generator running at a constant frequency and voltage rather than relying on an external speed governor for this purpose. In addition, it ensures that any power used for to raise and lower girds and DG sets has a power factor of one (UPF) even when under nonlinear loads. Syncing the PCC (Point of Common Coupling) voltage to the grid/generator voltage is also necessary to maintain continuous charging. The global environment is contaminated by the transportation industry's large carbon emissions. Electric vehicle (EV) adoption has a significant possibility to cut back on carbon emissions. A Battery Swapping Station (BSS) is an effective way to power electric vehicles while decreasing the time it takes to charge them at battery charging stations (BCS). For completing a lengthy interstate excursion, Swapping Technology offers the perfect option.
