This manuscript proposes a hybrid approach for multi-functional grid connected photovoltaic (PV) interleaved inverter using power quality improvement. The proposed approach is a combination of Spherical Evolution Search Algorithm (LSE) and Wild Horse Optimizer (WHO), therefore it is called LSE-WHO approach. The main objective of the proposed approach reduces DC voltage fluctuation and improves power quality. The interleaved inverter is utilized at the grid side, which consists of four legs and every leg contains a power electronic switch and a diode. Due to the configuration of interleaved inverter shoot-through effect is overcome. The system performance is enhanced by the utilization of interleaved inverter. The proposed approach operation is classified into 2 parts such as power harvesting and the harmonics reduction. The LSE approach is utilized to extract the maximum power of PV and the WHO approach is utilized to reduce the harmonics distortion and eliminated the DC link voltage fluctuation through double band hysteresis current controller (DBHCC). DBHCC provides lesser switching frequency, hence, the switching losses is low. By then, the LSE-WHO approach is implemented in the MATLAB site, its performance is compared to the existing approaches. From the simulation, it is conclude that the LSE-WHO approach provides the THD as 2.12% and increase the power quality.

A grid-connected photovoltaic (PV) system with interleaved inverter using a hybrid approach is presented in the paper. Generally, high deviation of DC voltage causes severe damage to the grid-linked system generate power quality issues. Therefore, a hybrid technique called LA-HBO, which is a combination of Lichtenberg optimization algorithm (LA) and heap-based optimizer, is proposed. The proposed method works with the interleaved inverter to realize a multifunctional operation and improve the power quality efficiency of the system. Here, LA techniques improve the power generated from PV and self-charging of the DC-link voltage control loop. The reference current signal is generated through the self-charging DC-link voltage control loop to eliminate the power quality issues. The double band hysteresis current controller generated a minimum switching frequency to provide low switching losses. A MATLAB platform is utilized to implement the proposed system, and the performance of the system is compared with other existing techniques. The test result validated that the proposed system can able to perform multilevel functions and produce power with high quality compared to other techniques. The value for the THD that achieves the proposed hybrid technique is 21.22%. The elapsed time of the proposed hybrid technique is 2.09 seconds.

The current needs of more nonlinear loads and the frequent usage of single-phase loads in three-phase system drastically create power quality issues in the grid-connected system. As a consequence, it creates an undesirable power quality issue (PQI) in the form of a change in the nature of voltage and current magnitude and waveforms in the power system. The voltage-related PQI leads to a huge disturbance in the system when compared with the current-related PQI. The hybrid series active power filter provides grids with the required voltage in series and suppresses the voltage-related harmonics caused by grid-connected nonlinear loads. The present work deals with an adaptive neurofuzzy inference system controller for the generation of a reference voltage signal that uses a reduced active filter rating. The simulation study was done in the MATLAB 2020b/Simulink environment and the experimental effectiveness of the proposed ANFIS controller was compared with that of a conventional controller. In the grid-connected system, this system prevents voltage quality problems such as voltage sag, flickering, voltage swell, neutral currents, and reactive power. The renewable energy sources interfaced into the DC-link minimize short and long voltage challenges so that they improve the overall performance of the system. In accordance with IEEE standard 519-1992, a prototype model was proved to demonstrate that the power delivery system works effectively under different conditions and reduces the total harmonic distortion by approximately 30%, which is less than the 5% acceptable limit.
