Abstract

Stand-alone photovoltaic (PV) systems have been used in remote electrification for decades due to their low infrastructure cost and clean energy source. However, their dependency on environmental conditions is a concerning issue. Therefore, backup energy storage is required along with a Maximum Power Point Tracking technique (MPPT). A dc-dc converter is usually used to implement MPPT before the inversion stage resulting in two-stage architecture. Meanwhile, single-stage conversion systems offer superior privileges in reducing the overall system's complexity, size, and cost. Among the single-stage boosting topologies, Split-Source Inverter (SSI) has been offered as an option with some advantages over the commonly used Z-source Inverter (ZSI). This paper presents step-by-step design procedures for a stand-alone PV system, including SSI and a Battery Storage System (BSS). Moreover, the small-signal model of the proposed system is analyzed to develop a robust control with superior dynamic characteristics. Finally, the control scheme is analyzed and simulated using MATLAB/Simulink.
