Economic load dispatch (ELD) is an important operational problem is formulated as an optimization problem of minimizing the fuel cost while satisfying several equality and inequality constraints. Usually the network loss is calculated using constant B-loss coefficients and net VSI (voltage stability index) is calculated sum of VSI of all load buses. More accurate solution due to can be obtained, if network loss and net VSI is calculated from load flow. A method involving the self adaptive firefly algorithm for solving the ELD problem for AC system has been developed. The firefly algorithm (FA), a heuristic numeric optimization algorithm inspired by the behavior of fireflies, appears to be a robust and reliable technique. This paper presents a self adaptive firefly algorithm for reducing both power losses and net VSI in power system. The proposed algorithm (PA) is applied to the standard IEEE 30 bus test system and the result are presented to demonstrate its effectiveness
