“…States (3) that active power will just be provided through every current vector matched with both the voltage vector u, whereas reactive power would be created by any current vector connected with V⊥. The subsequent formulations, particularly form the cornerstone of the IARC methodology to detect the reference currents [32], [34], may be employed to describe this idea:…”

Recently, the regulation of photovoltaic inverters, effectively under imbalanced voltages on the grid, has been crucial for the operation of grid-connected solar systems. In this regard, determining the output current reference is an integral aspect of managing a solar inverter with an unbalanced voltage. Based on evaluations of Instantaneous Active-reactive Control (IARC), Positive Negative Sequence Control (PNSC), Balanced Positive Sequence Control (BPSC), and Average Active-reactive Control (AARC), this paper proposes a novel variablecurrent-t-reference calculation method for minimizing power fluctuations and current harmonics. The controller is employed to regulate both constructive and destructive sequences inside a static framework, therefore enhancing dynamic performance and facilitating the selection of suitable controls in the presence of significant network defects. This study also suggests comparing the four MPPT methodologies examined (fuzzy logic, current only, Incremental Conductance, and Perturb & Observe) to maximize energy output. The simulation results efficiently validate the suggested computation approach that is presented in the current reference.INDEX TERMS Grid-connected PV system; output current reference; Dual controller; current harmonics; MPPT Techniques; and DC-DC Converter.
