In previous era, coal and oil like non‐renewable resources were mostly used for power generation, thus causing a severe environmental problem as well as high economic. An intelligent maximum power point tracking (MPPT) system was proposed to overwhelm the above‐mentioned impacts, which tracks the maximum generation of photovoltaic (PV) under various atmospheric conditions. Moreover, a modified DC‐DC converter was introduced to low inrush current and switching oscillation. The proposed model working process was split into three steps: first, design the normal PV with a grid‐integrated power system. Second, create a dataset with the aid of a designed PV model, and finally, design an intelligent MPPT controller based on that dataset. The difference among the MPPT and PV voltage was fed to an optimal controller that generates an appropriate pulse signal of the modified DC‐DC converter. The proposed intelligent tracking system was analyzed under various circumstances like static, dynamic and combined shading conditions. The proposed model offers 99.5% efficiency and very low harmonics values like 0.15% current total harmonic distortion (THD) and 0.46% voltage THD. The outcome verifies that the intelligent MPPT approach performs well than that of the currently used controllers in solar power generation and conditioning systems.

“…When the converter operates under ideal conditions, considering the phase change process, the 6kth characteristic harmonic voltage will be modulated on the AC side to be generated. For the system side, even if the corresponding 6kth ripple current generated by the 6kth characteristic harmonic voltage on the AC side is considered, the AC current and the 6kth ripple current are modulated by the switching function at the same time [4] . If the system voltage does not satisfy the ideal conditions and a non-characteristic harmonic voltage appears on the AC side, the corresponding noncharacteristic harmonic current will appear on the AC side after modulation by the switching function [5].…”

The current conventional power quality control method mainly realizes the control of power quality by designing the high voltage power control strategy for suppressing power routers, which leads to poor control effect due to ignoring the influence of harmonics. In this regard, the power quality control method of flexible AC transmission project based on harmonic suppression is proposed. The multi-objective voltage reactive harmonic optimization algorithm is designed, and the harmonic tidal wave voltage value is calculated, and the power quality control strategy is proposed. In the experiment, the control effect of the proposed method is verified. The experimental results show that when the proposed method is used for voltage control, the harmonic voltage distortion rate of the grid is low and has a more ideal power quality control performance.

Renewable energy penetration in distribution networks, especially wind turbines (WTs) and photovoltaics (PVs), leads to an increase in power quality disturbances. One of the most important power quality issues is flicker produced by WTs. Here, to mitigate the flicker produced by WTs, distribution network planning (DNP) problem is solved concerning flicker minimization. For this aim, a weighted objective function is defined in which in addition to power losses, flicker emission is also considered. In the planning problem, siting and sizing of WTs as well as siting of PVs are investigated to simultaneously minimize power losses and flicker emission. Owing to the difficulty of this optimization problem, a new variant of genetic algorithm (GA), named elitist‐based GA (EGA), is proposed whose crossover operator works based on the elite chromosome. This variant provides a promising way to efficiently use information from the best solution to generate new solutions. Simulation results show that optimal siting and sizing of WTs can considerably improve the network parameters in terms of power losses and flicker emission. Moreover, simulation results show the efficiency and effectiveness of EGA compared to the other studied techniques.
