This paper proposes the model and design of optimal utilization of grid connected Micro Grid (MG) system with Enhanced Fruit fly Optimization with Gradient Boosting Decision Tree (EFO-GBDT) based controller technique. The integration (modeling and design) of high performance converter topology is formulated with the consideration of enhanced converter efficiency, effective implementation, source of renewable energy and reduced swapping loss. In the proposed technique the control scheme is used to consolidate the performance of both an EFO algorithm and also GBDT. In the proposed technique, the EFOA plays out an estimate method to initiate an exact control signal systems and accumulates the control signal database, an offline way of light in power variety between the source side (source of renewable energy and battery) and load side. The performance of dataset used to work as the GBDT mode for an online way and it leads to the control procedure in less performance time. In this proposed technique, an objective function is determined by the system, data subject to be an equality and inequality restrictions. The restrictions are the sources of renewable energy, power require the storage of an charged elements. A battery is implemented as source energy and it is used to permit and balance the renewable power system units and to keep running at a steady and balance output power. At that point the proposed model is performed based on MATLAB/Simulink, its working platform and the performance is assessed based on the existing techniques.

“…The p-q theory is used, which is mainly based on a-b-c conversion into α-β-0 coordinates and α-β-0 conversation into a-b-c parameters, which are familiarly known as Clark's transformation and inverse transformation, respectively (Durairasan and Balasubramanian, 2020;Hari Prabhu and Sundararaju, 2020;Sureshkumar and Ponnusamy, 2020). The transformation is shown in Figures 6, 7, from which compensating currents are generated.…”

This paper presents the integration of renewable energy sources such as photovoltaics, wind, and batteries to the grid. The hybrid shunt active power filter (HSHAPF) is optimized with the Gray wolf optimization (GWO) and fractional order proportional integral controller (FOPI) for harmonic reduction under nonlinear and unbalanced load conditions. With the use of GWO, the parameters of FOPI are tuned, which effectively minimizes the harmonics. The proposed model has effectively compensated the total harmonic distortions when compared with without the filter and with the passive filter, the active power filter with a PI controller, and the GWO-FOPI-based controller. The performance of the proposed controller is tested under nonlinear and unbalanced conditions. The parameters of the FOPI controller are better tuned with the GWO technique. The comparative results reflect the best results of GWO-FOPI-based HSHAPF. The suggested controller is built in the MATLAB/Simulink Platform.

Hybrid Renewable energy sources (HRES) are rapidly increasingly compared to the traditional system since they are less effective to the environment and meet the huge demand required by the utilities. In the proposed paper the modelling, control and design analysis is implemented with PV, wind and battery as an energy storing device. The grid-interfacing inverter is regulated with a single-stage, three-phase RES-based distributed generation (DG) system. A genetic algorithm (GA) based shunt active power filter (SHAPF) is used to mitigate the power quality issues under nonlinear and unbalanced load conditions. The DG is grid-connected through a current-controlled -voltage source inverter (CC-VSI) via a DC link capacitor. Here the VSI is utilized to transfer the power from DG to the point of common coupling (PCC), SAPF to compensate for load current harmonics, under distorted supply voltage conditions, reactive power demand and load current imbalance. Both of these functions are important either individually or concurrently. As a result, the proposed controller regulates the power flow, controls it and acts as a SHAPF or does both at the same time. The proposed method is employed in the MATLAB/Simulink platform and performances were analysed.
