IMPLEMENTATION OF SOLAR PV ARRAY BASED MULTIFUNCTIONAL EV CHARGER USING FUZZY LOGIC CONTROLLER
Abstract
This research paper presents Analysis of Grid-PV based Electric Vehicle charger by using Fuzzy Logic Controller. A grid connected solar photo voltaic panel is considered to provide the continuous power supply to the household loads as well as to charge the electric vehicle. Mainly two cases are going to be considered here,They are grid connected mode and islanded mode. The generation of power from the solar PV panel changes due to climatical conditions. So, if variations happened in the system then the power supply to loads will get interrupted and there will be the possibility of occurring power quality related problems. So, at this point of time the grid comes into act and supply uninterruptable supply to the loads. In islanded mode of operation, the grid is going to disconnect by using a circuit breaker and the related performance can be evaluated. In this process, two converters are mainly used for the power conversion process namely Bi-directional (AC to DC) and (DC to DC) converter. By implementing the FLC (fuzzy logic controller) the charger can have seamless mode of operation. The Dc link voltage is regulated by using the proposed controller known as FLC to the system. The drawbacks that are occurred in the conventional methods can be overcome by using FLC Controller. The distortions in the harmonics can be reduced compared to the traditional SMC controller. At islanded condition, the charger is empowered for proving the support of active and reactive power in the modes of V2G and V2H. For generating sinusoidal reference grid current a SOGI-FLL based phase locked loop is utilized in the system.The simulation output of this proposed method can be assessed by using Matlab/Simulink R2018a software.
