Modelling and simulation of a PV battery grid backup system for various climatic zones of India

摘要

India has five climatic zones and the performances of renewable PV-battery systems in these zones vary widely. In literature where PV battery systems are simulated, only generic battery models are used which ignores the effect of temperature on battery performance. We extend these approaches to incorporate the thermal behavior of battery which helps in better predicting the performance, life and viability of microgrids powered by renewable sources with battery storage under different ambient conditions. In this present work, the influence of different climatic zones in India on the lifetime of the Pb-acid battery integrated with PV is simulated. Moreover, the life cycle costing is computed based on the lifetime to understand the viability of PV battery backup to grid in different climatic zones.
