The PV system is a different model established to encounter the request for electricity essential by numerous services. Primarily the features of any smart grid rest on reliability, performance optimization and efficiency. The planned article comprises of PV system, connected to a DC-DC converter then attached to a DC-link bus again converted to AC using an inverter and then fed to the grid. Optimization technique like Cuckoo Search Optimization MPPT is used to maximize the generated power and the structure is established in the MATLAB environment Simulink. The outcomes indicate the CSO is better compared to the P&O and PSO approaches.
