JPS_V5_N1_RP2 A Novel Loss Distribution Strategy after Removing Slack Bus using Improved Kinetic Gas Molecules Optimization Algorithm D. Srilatha S. Sivanagaraju Journal on Power Systems Engineering 2322–0376 5 1 10 25 Loss Allocation, Removing Slack Bus, IKGMO, Economic Aspect, Environmental Aspect The modern power system analysis, operation and control use pneumatic solution methodologies to solve more realistic power system problems to enhance the operational aspects of power systems. The conventional load flow methods work independent of economic and environmental aspects and allocates total power losses to slack bus which increases the burden on this generator. In this paper, a novel methodology to remove extra generation by the slack and to optimize the system operation in economic and environmental aspects is presented. Further, a new hybrid optimization algorithm namely Improved Kinetic Gas Molecules Optimization (IKGMO) is presented to solve Optimal Power Flow (OPF) problem while satisfying system equality and inequality constraints. The effectiveness of optimization over the conventional load flow in loss allocation is tested on standard IEEE-14 bus and IEEE-30 bus test systems with supporting numerical and graphical results.
