Abstract

Load shedding is considered one of the methods used in emergency situations to avoid instability and quickest recovery. In load shedding, anti-instability and spreading, it is important to quickly propose a reasonable load shedding strategy that will allow rapid recovery frequencies and the frequency values are acceptable. This paper presented the building of load shedding strategy that includes pre-designed rules based on the Fuzzy-AHP algorithm. The Fuzzy-AHP algorithm calculates the importance factor of the load in the electrical system. Load shedding are performed with low priority loads to help reduce the economic losses. When the electrical system is determined to be unstable, immediately, the load shedding control commands is executed, so the decision-making time is shortened and the damage caused by the load shedding is reduced compared to the traditional methods. The effectiveness of the proposed method is checked on the IEEE 39-bus system.
