This paper presents an analysis of the behavior of under frequency load shedding in isolated
power systems based thermal generation and renewable energy intrusion. Wherein the effect
of disturbances was studied in the system frequency due to changes in the load- generation
and as a serious disturbance influences load shedding to stabilize the system frequency.
In order to calibrate the frequency relays to perform load shedding every step drive using the
nonlinear optimization process generalized reduced gradient, which allowed to extract
minimum values of frequency change to a disturbance, and simultaneously calculate the
suitable loading rate in each step to disconnect the relay, avoiding unnecessary burden off.
Thus the effect of load shedding in the studied systems also allows us to see how it affects
the presence or absence of renewable generation in the system and the impact of these
sources of generation to the system frequency in steady state as to a disturbance. |
