ADDRESSING SOLAR IRRADIANCE INTERMITTENCY IN PHOTOVOLTAIC POWER SYSTEMS WITH INTEGRATED ELECTRIC VEHICLE CHARGING CAPABILITY

Abstract

Relief of the changeability in yield force of sustainable generators, for example, sun powered photovoltaic (PV) frameworks is a developing worry as these generators arrive at higher entrances on electric networks. Moreover, expanded infiltration of electric vehicle (EV) loads presents a test for circulation feeders. The high-voltage dc bus of a PV inverter is connected to the EV battery by a bidirectional, highly efficient dc–dc EV charger, as shown in this paper. By providing the EV battery with quick charging from the PV system, the system reduces feeder overloading in part. Moreover, the charger is fit for redirecting quick changes in PV power result to the battery, subsequently decreasing the pace of progress of inverter yield capacity to a level beneath the slope pace of existing network assets. The paper tends to estimating of the charger and energy stockpiling in view of the PV framework rating, the ideal greatest slope rate, and site sun powered light qualities, including geographic scattering of PV exhibits. Examination proposes that modest quantities of energy stockpiling can achieve enormous decreases in yield power slope rate. Trial results are displayed for a 10 kW, 98% productive dc charger in light of bidirectional four-stage zero-voltage-exchanging converter.
