Enhanced under frequency load shedding (UFLS) schemes performance in Sabah Grid System
In the last five decade, peoples can survive successfully even without the existing of electrical energy. Nowadays, electricity is one of the important aspects for human being to run their daily life. Generation capacity should increase in proportion to the increase of its loads, but, if there...

In the last five decade, peoples can survive successfully even without the existing of
electrical energy. Nowadays, electricity is one of the important aspects for human being
to run their daily life. Generation capacity should increase in proportion to the increase
of its loads, but, if there are sudden changes in the system generation capacity through
loss of generator or due to line tripping can produce severe generation-load imbalance.
Under frequency load shedding scheme is implemented to restore power system
frequency stability if system frequency drops below the operational set point during
major disturbance such as lost of generation. Different countries/utility companies have
their own philosophies in implementing the under frequency load shedding scheme.
Generally, it is based on country/utility requirements, e.g. the overall power system
network and the country’s demographic. As the main power utility in Sabah, Sabah
Electricity Sdn Bhd (SESB) takes the responsibility to ensure that the daily operation are
always operated in a reliable and secure condition in supplying power to the consumers.
This project presents the principles and implementation of the under frequency load
shedding (UFLS) scheme and conducted through simulation of 150,000 test bus-system
in Sabah Grid System. The performance of the existing schemes under various
conditions of disturbance were compared and analyzed. All the simulation works were
performed using Siemens PTI software Power System Simulator for Engineering
(PSS/E). |
