Abstract
The incorporation of Energy Storage Systems (ESS) has become vital in advanced power systems, especially with the enhancement of penetration of Renewable Energy Sources (RES) and rapid development of Electric Vehicles (EVs). Batteries are exploited among distinct ESS, because of their reliability, compact size and quick dynamic response, making them appropriate for grid-connected applications. Nevertheless, efficient battery incorporation requires advanced power conversion and management approaches. This research develops an innovative approach for improving power conversion efficacy and battery management in Photovoltaic (PV) related EV systems via a Switched Quasi Z-source (SQZSC) converter coupled with an active balancing circuit. The low voltage of the PV system is solved by the SQZSC converter to offer maximum voltage gain and efficacy. Moreover, a Maximum Power Point Tracking (MPPT) based on Radial Basis Function Networks (RBFNN) approach is utilized to assure effective power extraction in dynamic conditions. To regulate the delivery of power when no power is available from PV, a bidirectional battery balancing circuit is exploited that adapts the voltage level based on the battery state and is managed by a Proportional Integral (PI) controller. The implemented work is implemented in MATLAB/Simulink, the outcomes validate that the developed balancing approach achieves inferior switching loss in the equalization period, in addition to enhancing the performance of bidirectional battery equalization.
