Integration of Solar PV System with Storage Battery System

Abstract

AbstractEvery year, a lot of work is carried on the development of hybrid energy systems for constant and continuous output power to everyone at affordable prices. Hybrid energy systems are preferred more because of the irregular patterns in energy availability from the renewable energy systems alone. The irregularity is due to the changing nature which is not avoidable and this irregularity results in output voltage fluctuations, which further leads to the damage for the machine operating system working under steady supply. So, in this paper, a hybrid system is designed by integrating a solar photovoltaic system with a storage battery system for steady and constant supply even though variable parameters are present. In recent developments, the battery system has become a feasible energy storage device for integrating it with solar energy and thus converting solar energy into a more steady and reliable power source. The control of charging and discharging state of the battery is carried by a bidirectional DC-DC converter. Different irradiance levels are the inputs for this paperwork. This work provides basic information about the simulation and working of a solar photovoltaic system integrated with a battery system. The storage technology plays a vital role in providing continuity for power supply to the load. The load taken is a DC load equivalent to the small loads used in our households. The reason for considering the DC load is to ensure the proper functioning of the system. The simulated results obtained from the designed hybrid energy system output voltage show some better performance and reliability. The small rating loads such as fans, lights, mobiles, and laptops, can be used as a load for the designed methodology and it will ensure the continuous supply of the power with minimal cost price in terms of consumption.KeywordsSolar photovoltaicBatteryMPPT algorithmHybrid energy systemBidirectional DC-DC converter
