A study on highly efficient BBFIC for grid connected photovoltaic battery energy storage system using optimization techniques

Abstract

A wide range of community stakeholders have given renewable newlineenergy resources a lot of attention in recent years since they may be used to newlinegenerate electricity without threatening environmental protection. Solar cells newlinehave gained popularity among real-time users due to a number of benefits, newlineincluding low cost and advanced technology. These models undergo a great newlinedeal of modifications in their power generating phases, starting with the newlineconversion of AC input to DC output. As a result, operating the power system newlinewith a high efficiency output-based converter becomes very challenging. newlineA high voltage conversion ratio is necessary for the majority of newlinethese applications. On the other hand, basic switching converters have a low newlinevoltage conversion ratio. High gain power converter development has drawn a newlinelot of interest. The operation of DC sources or loads may be hampered by newlinehigh ripple currents and voltages at the input and output of DC-DC newlineconverters. newlineThe use of DC-to-DC converters is required for low potential newlinesources like batteries, SPV panels, and fuel cells. A significant step-up newlineconversion is therefore necessary. newlineA DC-to-DC converter takes an unregulated DC voltage input and newlineconverts it to a constant or regulated voltage output. Linear and switching newlineregulators are the two basic types of regulators. A power transfer stage and newlinecontrol circuitry are present in all regulators, which sense the output voltage newlineand change the power transfer stage to maintain a constant output voltage. newlineBecause a feedback loop is essential to sustain regulation, compensation is newlinerequired to keep the loop stable. Different control schemes require different newlinecompensation strategies, and a modest signal analysis of the system is newlinerequired to develop a stable compensation circuit. newline
