“…The presented method averts the usage of linear with NLCs, also it could not involve the modulator, so it was a simple method and the control strategy was simply to execute. Iqbal et al 26 have introduced a novel method for MG connected UPQC that regulates the VSCs switch of UPQC by considering the error derivative in three various stages, then combines over time, when enhancement through three gains, to enhance its stability with efficiency toward PQ issues. Here, sensing depending on fuzzy logic was utilized to induce the series switching or shunt compensators for conditioning any voltage sag/swell, voltage transients, current harmonics, current with voltage imbalance issue.…”

In this manuscript, a novel control scheme is proposed to achieve the power quality (PQ) enhancement of renewable energy sources (RES), such as photovoltaic (PV), wind turbine (WT), fuel cell (FC), and battery. The proposed hybrid technique is the consolidation of both the Improved Bat Algorithm (IBat) and Moth Flame Optimization Algorithm (MFOA), therefore it is known as Improved Bat search Algorithm with Moth Flame Optimization Algorithm (IBatMFOA) control strategy. The crossover and mutation function is utilized to modify the bats search behavior function. Here, MFOA is utilized to enhance the searching behavior of IBat technique by reducing the error function. The main goal of proposed IBatMFOA approach is "to enhance the PQ depending on active with reactive power varience." To attain the target, MFOA is optimized to lessen the power variation. Moreover, the functioning cost of RESs is diminished based on daily with weekly data forecast, like grid electricity price, electrical load, environmental parameters. By using IBatMFOA technique, the entire system efficiency is enhanced. By then, the proposed method is activated in MATLAB site, then the performance is examined with existing methods, like artificial bee colony, Gravitational Search Algorithm, and Firefly algorithm. The active power controller parameters of proposed technique are 8.8554 and 1.8569. The reactive power controller parameters of proposed technique are 8.1657 and 1.5698.active with reactive power, micro grid, power quality enhancement | INTRODUCTIONNowadays, most renewable energy sources (RES) with distributed generation (DG) units, including photovoltaic (PV) arrays and fuel cell (FC) 1,2 are directly produce the DC output energy, but other sources, viz micro turbines, Wind

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.

This paper proposes a coordination method for the voltage control devices based on optimal settings of the D-STATCOMs, on the load tap changer (OLTC) transformer and the distributed generations (DGs)-based renewable energy resources (RERs). The central controller is introduced to handle the active smart distribution network (SDN) problems to maintain the voltage profile within its permissible limits, minimize power losses in different operating conditions, and minimize the energy wastage from the distributed renewable energy resources. These problems are formulated as a multi-objective optimization problem. With increasing load demand and RERs in the distribution system, voltage coordination threatens real-time efficiency. In this research work, central controller-based Gorilla Troops optimization (GTO) algorithm is proposed to detect the optimum solutions for the voltage coordination problem. The load demand uncertainty and the stochastic nature of power generated from RERs (PV panels and wind turbines) are considered in the voltage coordination problem due to their significant effects on the operation and planning of the SDN. The proposed SDN has been represented based on the Internet of Things (IoT) communication protocol. It enhances the data and information transfer between the system-connected agents. A practical test system, NDEDC-24 bus radial distribution network from the North Delta Electrical Distribution Company and IEEE-33 node system are used to test and evaluate the proposed method. The results are compared with other well-known evolutionary methods. The proposed method obtains more accurate results than the other methods.INDEX TERMS D-STATCOM, distribution network, Internet of Things, on-load tap changer, voltage coordination.
