Abstract


Power generation from renewable energy sources is playing a significant role in today's world, where conventional energy sources are scarce and pollution of the environment is on the rise. Among them sun powered and wind are notable environmentally friendly power source, which definitely stand out from the concerned. Solar energy is a promising, popular, and alternative source due to its abundance, pollution-free, renewable, and maintenance-free qualities. A review of a standalone photovoltaic (PV) system with a storage device as a backup source serves as the foundation for this work. The best option is to run a PV system on its own in remote areas that aren't connected to the utility grid. However, solar energy is not always available throughout the day due to the earth's diurnal cycle and the climate, and PV generation may not always be sufficient to meet the fluctuating local load's power demand. As a result, the PV system is unstable because it is unable to provide steady power to the connected load in a standalone PV system. In order to improve the dispatchability and stability of this intermittent PV power, it is necessary to consider the utilization of specialized energy storage systems. At this point, the storage device is primarily thought to be a lead-acid battery because of its low cost and large size, making it ideal for high-power applications like solar and wind systems.
