Sliding Mode Control Technique for Single Phase Sub Module Integrated PV System
Ms. Jyoti C. Deshmukh, Prof. Sampath Kumar Bodapatla, Dr. P.Mallikarjun sharma
The photovoltaic (PV) system that is based on sub module-integrated converters (subMICs) is capable of maximizing solar energy harvest by eradicating power losses due to intra panel mismatch. This paper presents an improved procedure to design a sliding controller for the PV system, which drives the PV voltage to follow a reference provided by an external MPPT algorithm and mitigates the perturbations caused by the irradiance changes and oscillations in the bulk voltage. By considering that the switching surface is the linear combination of the input capacitor current and the PV voltage error, the proposed design exhibits advantages in comparison with existing solutions that rely in the linearization of inner current loop dynamics. However, the simulation of such systems can be very challenging due to the large number of switching-mode power units, nonlinear nature of PV generators, and complication of the coordinating control. This paper provides an effective solution to simulate and control, single-phase grid-tied PV systems that are based on a practical subMICs configuration by sliding mode control. The approach includes the simplified PV cell model and averaged model for power converters, which consider all dynamic interactions among the maximum power point tracking (MPPT).
