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.
