Abstract

Power systems are usually exposed to numerous disturbances that can have an adverse effect on system
operation. Insufficient generation could lead to frequency declination and subsequently system collapse
in the absence of immediate control action. Frequency Load Shedding (UFLS) is a technique commonly
applied to overcome overloading and restore the system frequency. This paper presents an adaptive load
shedding approach to determine the best location with minimum amount of load to be shed. Load Ranking
Fuzzy Logic (LRFL) is used to rank the load based on their sensitivity and stability index. In order to
achieve this, the proposed strategy is verified using 11 kV Malaysian distributed network consisting of
different type of loads connected with single and multiple Distribution Generator (DG). The simulation
results show that the proposed strategy successfully stabilizes the system’s frequency.
