Solar PV system for off-grid applications is growing at a faster rate because of its compatibility and ease of implementation. The modern smart building consists of hybrid AC and DC loads. The solar PV system generates DC power and can also supply the DC loads. To supply the AC loads, the DC power need conversion to AC using a DC-AC converter. A general solar PV system consists of two stages, one is to extract the maximum power and the other one is to convert it into a suitable DC or AC. Here, a single-stage multi-functional converter (MFC) is employed, which extracts maximum power and supplies to both AC and DC loads. To overcome the intermittency of solar PV output, battery energy storage is interfaced through a non-isolated buck-boost converter. The MFC operates in two modes, i.e. hybrid power flow mode and inverter mode, depending upon the availability of solar PV output. The proposed system is simulated using the PSCAD/EMTDC software. An experimental test setup using solar array simulator and a multifunctional power electronics converter has been developed for demonstration of the results. The control algorithms are implemented using NI PXI-7842R series FPGA controller through LabVIEW platform.

“…A DC–DC converter operates the solar array at its peak value by using the MPPT algorithms. Among all algorithms, P&O and incremental conductance (INC) are easiest and most effective to implement in off‐grid small residential applications [3, 4]. In solar PV smart residential applications, the hybrid AC and DC loads are getting popular.…”

This study proposes a solar photovoltaic (PV) based nanogrid with integration of battery energy storage to supply both AC and DC loads using single-stage hybrid converter. A boost derived hybrid converter (BDHC) is used as a single-stage converter to supply the AC/DC hybrid loads. The BDHC reduces the number of conversion stages when compared to the conventional solar PV based systems to supply the AC/DC loads. A non-isolated buck-boost bidirectional DC-DC converter is used for charging and discharging of the battery to support the nanogrid. The power reference algorithm proposed in this study provides the proper utilisation of the solar PV in different operating conditions and uninterruptable power supply to the loads along with the battery storage management. A modulation scheme is implemented to operate the BDHC for generation of AC/DC hybrid outputs from a single input. The performance of the proposed system in different modes of operation has been evaluated using PSCAD simulation studies. A laboratory experimental setup is developed and control algorithms are implemented using LabVIEW based FPGA controller for verification of the results.
