Abstract


The main aim of this paper is to propose a concept of PLL based ST switching control method which is used between islanding and grid connected modes. In this paper the Phase Locked Loop is used to maintain phase synchronization between grid voltages and load voltages in cased of grid connected mode, and also as well as in islanding condition. In this the stability of both current loop control and voltage control loop control for both grid and islanding modes is analyzed. This paper also proposes the concept of renewable energy source (Solar System) as distributed generating source for grid connected system, since the renewable sources are present leading generating sources. The performance of this proposed system is verified by using Matlab/Simulink tools.


Keywords


Phase Locked Loop, Photovoltaic System, Seamless transfer, Grid and Islanding Conditions.
