Simulation and Evaluation of micro-grid synchronization with main network
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 12
Abstract
Nowadays, due to their high reliability, Micro-grids have improved dramatically. Micro-grids work in two main modes: islands and a network connection. Under certain conditions, the micro-grid is connected or disconnected to the main network. Synchronization of a Micro-grid with the main network must be done when the voltage of micro-grid is in synchronization with the voltage of main network. Phase-locked loops are responsible for detection of phases of micro-grid and main network voltages and when the two voltages were synchronized, micro-grid is connected to the main network. This article studies and simulates the connection of a micro-grid to the main network when the voltages are synchronized and asynchronized.
