Abstract: In this paper, a vector-based synchronization technique is proposed for the synchronization of a solar photovoltaic (PV)-battery system to the grid. In this technique, the three-phase grid and point of common coupling voltages are transformed into two vectors in the α – β plane.
Solar photovoltaic is one of the most emerging and greener renewable sources of electric power. Integrating a PV system into a power grid system poses certain issues in terms of utility power grid stability and power quality. The main problem is the phenomenon of islanding. Therefore, Anti-islanding protection is an essential feature of every grid …
