| dc.description.abstract | The penetration of power electronic converter into the power grid is increasing at a noticeable rate, which causes the number of conventional synchronous generators (SG) to decrease. As a result, the power electronic converter dominated power systems is lacking system damping and inertia. Consequently, the renewable energy source (RES) based grids are now vulnerable to various transient instabilities.
Swing equation-based virtual inertia (VI) emerged as the solution to the problem. The researchers proposed different swing equations with different terminologies and methodologies to implement VI. The GFCs mimic the inertial and damping response and make the pulse width modulator (PWM) converter to replicate the behaviour of SG. So, from the point of view of the grid, the PWM plays the role of SG.
The objective of this thesis is to analyze the rate of change of frequency (RoCoF), the inertial response and the influence of the grid forming converters in the dynamic performance of power system considering high penetration. | |
