Abstract |
|
In this paper, an Optimal Load Shedding problem pertaining to system overloading is solved using the Firefly Algorithm (FA), a swarm-intelligence based, bio-inspired algorithm. The related objective functions, viz. the amount of load shedding and the New Voltage Stability Index (NVSI), indicating the optimal location of load to be shed, are minimized by the proposed algorithm. The NVSI acts as a voltage stability indicator in transmission line and its minimization improves transmission line performance, thus improving voltage stability of the system. The proposed algorithm is applied on a standard IEEE 30-bus test system for the overloading criterion. This paper implements the effectiveness of the Firefly Algorithm in solving the multi-objective problem. |
