Active Power Loss Minimization in Electric Power Systems Through Artificial Bee Colony Algorithm

Reactive power optimization (RPO) is an important area of study to provide working for power systems in a secure and economical way. RPO is used for the voltage control, decreasing of active power losses, and for the optimization of the power coefficients. In RPO the non-linear power loss function is used as a purpose function to be minimized. The control parameters of that function are bus voltages of the generators, level settings of transformers and the reactive power output values of the capacitors added to buses. Artificial Bee Colony (ABC) algorithm, one of the intuitive methods is used in this optimization study. In this study, by using the ABC algorithm, RPO provided on the IEEE 6-bus and IEEE 30-bus test systems. The ABC algorithm is compared with some heuristic algorithms. It is shown by the results that active power losses can be decreased by ABC algorithm. Copyright (C) 2010 Praise Worthy Prize S.r.l - All rights reserved
