Summary In grid‐connected (GC) photovoltaic (PV) system with a three‐phase voltage source inverter (VSI), one major requirement is that the DC‐side voltage should be greater than the inverter AC‐side voltage. In many PV installations, this is difficult to attain without an additional DC‐DC converter. For such scenarios, a three‐phase differential boost inverter, where input DC voltage can be less than AC‐side voltage, is a promising configuration. For GC PV systems integrated with such power electronic switching converters, the power quality control also plays a significant importance. In this paper, a novel power quality control technique for such a GC PV system based on three‐phase differential boost inverter has been proposed and evaluated. The proposed control system consists of three subsystem level control loops: (1) a novel control unit for reference voltage generation required for power quality improvement, (2) a double‐loop control strategy with plug‐in–type repetitive Proportional‐Integral (PI) control for outer loop and feedback linearizing control for inner loop meant for tracking of boost inverter output reference voltages, and (3) another bidirectional DC‐DC converter controller for battery operation. The performance of the proposed control algorithms has been tested under various scenarios, ie, power management, transition between GC to stand‐alone (SA) modes and vice versa, and grid current compensation under unbalanced load, nonlinear load, and unbalanced and distorted grid voltage conditions. Extensive simulation and experimental results are reported for validating the proposed control technique.

“…The PVP is equipped with a Maximum Power point Tracker (MPPT) [13] which is an electronic device that monitors PVP generation to operate near its maximum power point along the I-V curve and an inverter that provides the same output voltage as the electric grid (230 V/50 Hz) [7].…”

“…This mode is adopted when the network is not available or when the equipment function depends only on the sun occurrence (pumping, lighting, air-conditioning, heating, etc.). Research interests are essentially related to the modelling [2][3][4][5], the optimization [6] and the adaptation system [7] of the PVP supply according to equipment needs. As for researches carried out on grid connected PVP, they generally deal with system assessment and characterization depending on site climate [8,9].…”

This study introduces a new switching mean giving a real time optimum connection mode of domestic apparatus on either the electrical grid or a photovoltaic panel (PVP) output. A fuzzy algorithm makes the decision which ensures the optimal energy management basing on the PVP generation and apparatus states with respect to energy save criteria. Validation was driven on a 1kW peak (kWp) PVP and domicile apparatus of different powers installed at the Energy and Thermal Research Centre (CRTEn) in the north of Tunisia. Results confirm that energy save during daylight reaches 90% of the PVP generated energy.
