Abstract
This paper deals with the design, modeling and performance evaluation of standalone solar-PV (Photo- Voltaic) system using interval type FLC (Fuzzy Logic Controller) based MPPT (Maximum Power Point Tracking) controller. The proposed system is designed for a 5 kW solar-PV generating system. The system consists of a solar-PV array connected with the single phase VSI (Voltage Source Inverter) through a MPPT controller and an LCL filter is used to feed the power to the consumer loads. The design procedure and modeling of the system components and controller is presented in detail. The performance of the system is evaluated in steady and dynamic system conditions to validate its design and model. The voltage controller is designed to maintain the dc link voltage and performing under varying input voltages. The output voltage and current regulator is designed to maintain the power quality under varying consumer loads and results are presented for THD (Total Harmonic Distortion) which are found under the limits of 5%.
