Sažetak
Nowadays, Photovoltaic (PV) system’s contribution to the power grid is increasing immensely.
The PV system is linked with power grid through one or more inverters and a power conditioning unit to ensure smooth power delivery while also maintaining system voltage and frequency
stability. However, due to grid load expansion, weak power grids have emerged as the dominant
one today. As a result, the voltage and frequency of the grid got distorted. It may cause serious
damage to the entire system in some cases. A single phase ZSI with the proposed Fractional order
SMC technique is used to address these issues. The single phase ZSI consists of only two power
switches and perpetuates the voltage transfer ratio like full bridge inverter. It also corroborates
the sharing of power, regulatesactivepower,voltage, frequency, reactive powerand alleviates the
harmonics in current. The input voltage of inverter is boostedby using theshoot through state
and it also improvesthe reliability of inverter. The execution of the single phaseZSI withproposed
FOSMCtechnique is assessed in MATLAB/Simulink to bear out the magnificent features of the
proposed FOSMC in weak grid.
