Uninterruptable PV-battery based grid tied PV inverter using cascaded FLC MPPT and high gain BIFRED DC-DC converter

Energy storage and interfacing the energy storage device to the grid have become increasingly essential with the rise in demand for the production of electricity from renewable energy sources. Continuous supply of energy to the grid obtained by using Photovoltaic (PV) systems. The output from the PV system is intermittent so that a DC-DC converter is used to step up/step down the output. In this paper, a Boost integrated flyback rectifier energy storage DC-DC (BIFRED) converter that can supply both AC and DC loads from a solar-powered PV to the nano grid. The output from the PV module is fed to the cascaded FLC (Fuzzy Logic Controller) using MPPT algorithm which generates the gating pulses and delivers them to the inverter. Inverter fed PV grid topologies are used to meet energy needs and link green energies into power grids. One of the additional benefits delivered by PV is reactive power. In order to compensate for reactive power in localized networks, reactive power from the inverter should be fed into the grid. Results for varied irradiance and temperature circumstances are obtained using a simulation model for solar panels and MPPT based fuzzy logic controller. Making use of batteries is ideal for conventional sources of energy such as solar, wind, etc. For charging and discharging of the batteries, a bidirectional DC-DC converter battery is used. Moreover, 1ϕ VSI is linked to the grid and developed by using FLC. The MATLAB simulation model verify the usefulness of the proposed control technique. The results of the simulated responses having the efficiency of 95.8% and 1:12 of voltage gain.
