Modeling and design of a three-phase grid connected PV system based on PWM current source inverter and P-I curve slope MPPT technique

This paper describes a sensorless photovoltaic grid connected system using a MPPT technique based on optimal slope of P-I curve of power load. This system is composed of only one stage: SPWM current source inverter. This system operates without sensor and without tuning. Modeling is presented and a multi-objectives design is performed. The results are validated by simulation in the Matlab-Simulink environment.
