Abstract

The research on using and exploiting effectively Distributed Generations (DGs) to generate electricity is meaningful to reduce the climate change and dependence of power demand on fossil energy sources, which are at risk of both being exhausted and causing environmental pollution. The use of Power System Stabilizers (PSS) in grid connection confrol of distributed generation is to provide improved stabilization of the system. It is not similar to conventional power plants, distributed generations have small scales in comparison to those of networks. Therefore, despite having an advantage to reduce the dependenece of on traditional power plants, the integration of DGs into power supply systems is still a major issue. The article presents simulation result of the grid-connected control model of DGs using power system stabilizers, which maintains maximum capacity of the systems with irrespective of connected power loads.

Key words: Power System Stability; Power Stability; excitation system; distributed generation; grid-connected distributed generation.
