PROJECT TITLE :

A New Simulation Modeling for Nonlinear Current Control in Single Phase Grid Connected PV System

ABSTRACT:

Nonlinear current control schemes for single-phase grid-connected PV systems yielded better outcomes than linear current control schemes. However, designing its controller is a time-consuming task. A nonlinear current control approach for single-phase grid-connected solar systems is described in this paper. The maximum power that can be given to the load is controlled using a partial feedback linearization technique. The Lyapunov function is used to calculate the nonlinear reference input current. To maintain PV system stability, a function has been developed. Simulation software is used to assess the system's performance for variables such as changes in atmospheric conditions. In order to verify its design characteristics, a comparison with classic controllers is also carried out.
