摘要：

Single-phase inverters integrating battery storage and renewable energy sources are becoming popular among residential electricity consumers because of the need for reliable and quality power, pollution reduction, and savings in electricity costs. Gird-connected inverters have a multi-mode operation and are preferable over isolated ones, but their high complexity and cost are a concern. Battery integration with such inverters requires a high-voltage battery bank, which increases the cost further. Also, most single-phase grid-tied inverters don't support power quality compensation. This paper proposes an integrated power converter system forming a single-phase home grid, addressing the abovementioned issues. The proposed approach integrates a low-voltage battery (48V) at the DC link of the grid-tied inverter using a high-gain bidirectional converter. It also enhances the capability of the single-phase grid-tied inverter to compensate for the power quality issues such as reactive power and nonlinear current of the load. The proposed system is validated using MATLAB/Simulink simulation.
