Abstract

In this research paper, the study on how the under frequency load shedding (UFLS) and under voltage load shedding (UVLS) can be affected the islanding operation in distribution network has been reviewed and implemented. By exploring the methods of UFLS and UVLS and implemented, problems during islanding can be solved. UFLS and UVLS slowly becomes significant for the islanding in distribution network due to it can precise determine the location of load to be shed and amount of load to be shed. Hence, the proposed technique for UFLS and UVLS is presented in order to achieve the optimum load shedding when islanding is occurs. 2 different types of 11 kV distribution network will be used to determine the proposed method. The presented UFLS consists 3 different type of load shedding module which is Load Shedding Controller Module (LSCM), Stability Index Controller Module (SICM) and Optimum Load Shedding Module (OLSM) while UVLS consists 2 type of load shedding module which is Load Shedding Controller Module (LSCM) and Stability Index Controller Module (SICM). The proposed technique is modelled by using DigSilent Power Factory Software. In addition, this paper is only consider intentional islanding (event based) and conventional load shedding. Besides, the effectiveness of proposed UFLS and UVLS scheme is compared to the conventional UFLS and UVLS. The output result of proposed load shedding method is discussed and studied. Lastly, the results shows that the proposed UFLS and UVLS technique has achieving the optimum load shedding. In short, the most suitable of load shedding method for UFLS and UVLS is proposed load shedding technique.
