Optimal controller design for high performance of solar energy for grid-connected systems

Engineers are searching for alternatives to conventional sources of electricity to solve the energy crisis as a result of the sharp increase in energy usage. The design, simulations, and investigation of a three-phase, 10.44 kW solar energy system are presented in this study. PV analysis is also done. The photovoltaic system consists of six concurrent strings, each consisting of four photovoltaic cells connected in series, and an inverter that provides a two-way flow of energy. The output of a Phase Lock Loop (PLL) comments linearization system is utilized for generating a signal, and the power converting voltage is synchronized with the signal using this reference voltage. Two stages that are most appropriate for the battery's rechargeable charging process are chosen to replenish a battery bank in either quantity or float arrangement for eight sequences of 12.5 V and 200 Ah rechargeable battery packs. The designed photovoltaic (PV) system falls under the category of hybrid systems. Not to mention, a MATLAB computer model has been developed for a grid-dependent solar PV system that makes use of a sinusoidal pulse width modulator and a voltage source inverter.
