Design of Switched Z-Source Converter for Grid Tied PV with Hybrid Storage System

Despite being essential parts of modern distribution networks, photovoltaic (PV) modules were previously employed primarily to produce money-making, ecofriendly electricity. Due to inverters with integrated Maximum Power Point Tracking (MPPT) algorithms, PV systems frequently reach their maximum power point while functioning effectively during the day. This article describes a method for MPPT prediction utilizing data on solar contact and ambient temperature called a Modified P&O based MPPT. The proposed method offers quick response, non-intrusive sampling, which is overall harmonic distortion reduction, better PV unit utilization, and simple MPPT algorithm training. An architecture for a switched Z-source converter is projected in this paper. In hybrid and renewable systems that store electricity, super capacitors have been employed as batteries to manage the source and the grid. Stable voltages are produced by using these devices. Combining switched-capacitor cells with common Z-source impedance networks results in a groundbreaking high step-up converter. The proposed converter provides a high voltage gain while limiting the responsibility of sequencing or needing an excessive amount of elements, while reducing the voltage demand on the diodes and the power switch to less than half the output voltage. The results of the simulation and testing are used to determine the productivity and position of the proposed converter. The comparison of the converters shows the greater efficiency of Switched Z-Source Converter as 93.6%.
