A Grid-Connected Solar PV/Wind Turbine Based Hybrid Energy System Using ANFIS Controller for Hybrid Series Active Power Filter to Improve the Power Quality

Abstract

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.

TS fuzzy control of PV assisted single phase three phase induction motor drive for rural pumping applications

“…The applications that are related to Grid-connected are used to exchange energy with the utility grid and supply energy for local loads, as opposed to standalone PV systems, which can only offer electricity for distant loads that lack a source of power. The DC current from the PV module is transformed into alternating current in a solar PV system by an inverter that is connected to the grid [17]. After meeting the current demand, the PV system can transmit the excess energy to the grid when it is connected to it.…”

“…Te several algorithms that are now in use to regulate DLCV regulation, current control methods, harmonic separation approaches, and SHAPF functioning are described [6]. In the meantime, ANFIS was used to manage the series flter in order to handle voltage-related troubles [7]. Te distributed energy system, which mixes PV and wind, was constructed to minimize load fuctuations and enable a smooth transition between the grid and the island [8].…”
