Micro grid is a latest concept for upcoming energy distribution system that enables, renewable energy integration. It generally combination of multiple distributed generations (DG's), that are usually connected to the grid through power inverters. During the islanding operation (autonomous mode) of grid, important task are to share the load demand among multiple parallel connected inverters proportionately,...
Renewable energy importance increases all over the world. Conversion of power from one level to another level achieved by using power switching devices. The performance of the converters mostly depends on its switching process. For maintaining the voltage at output constant irrespective of variations in DC input voltage and the load current, a control system must be required for the converter. This...
Various Islanding Detection Methods (IDMs) for distributed generations are reviewed in this paper. Special consequence is put on some of the islanding detection systems based on “active methods” and “Passive Methods” for distributed generations based system. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered. Moreover, extended islanding can also prevent...
Power Quality is one of the critical issues in the power distribution system operations, nowadays. Due to implementation of complex power device, their performance becomes very sensitive with the quality of power supply. This paper demonstrates the application of a dynamic voltage restorer to resolve the quality problems of the voltage Sags/Swells which may be severe for many sensitive loads. The...
