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...
