Abstract

Stability is the most important feature of power system networks. But the inclusion of power electronic devices has negative impedance instability. In addition to that local instabilities may arise due to converter when interacting with the other dynamic subsystems. This paper discusses a simple control technique for inter connection of distributed generation resources to the AC power grid tied converters. The concerned method introduces a required active signal at the control loop of the converter due to which the input impedance of the grid tied converter changes. Simulations are conducted in SIMULINK , used to examine the performance of the system after the application of control technique.
