Abstract :
This paper presents modeling, simulation and performance evaluation of grid integrated photovoltaic (PV) with battery energy storage system (BESS). The battery energy storage provides additional benefit for DC bus voltage regulation, where it is interfaced to the common DC bus of the PV power conversion system. A control method for state of charge and BESS charge/discharge is proposed to ensure an efficient performance and safe operation of the BESS. The dynamic performance of the system during critical condition is evaluated by considering various simulation scenarios in which the system is subjected to disturbances such as step changes in solar irradiation and fault at the utility grid. The PSCAD/EMTDC based simulation provides the evaluation results.
