PV-battery based single phase microgrid with grid synchronization and de-synchronization capabilities

In this paper presents an integration of battery with a PV grid tied based single phase microgrid with multifaceted facilities. The proposed PV-battery grid tied system has capability to perform in dual mode i.e. grid integrated mode and islanded mode, according to the availability of grid. The proposed system has multipurpose control for VSC (Voltage Source Converter), for power transfer, harmonic elimination and provides power balance to the microgrid. The purpose of this system is to supply uninterrupted power to the load at less PV generation or grid fault condition or at peak load condition by using a battery. This system is modeled in MATLAB and developed model is used to simulate its performance. Simulation results are analyzed the performance and the response of microgrid with an adaptive algorithm with frequency and voltage control under mode transition condition.
