Abstract
Objective. A modified imperialist competitive algorithm adapted to find the optimal distribu-tion network configuration with minimum active power losses is proposed. Technique. The pro-posed algorithm was used to solve the distribution network reconfiguration problem formulated as a multi-objective mixed-integer combinatorial nonlinear optimization problem with equality and inequality constraints that include a maximum active power losses reduction, maintaining of the bus voltages within a predefined limits, excepting the current overload of the network's branches, keeping the radial network structure and load connectivity. Results. A flow chart of the modified imperialist competitive algorithm to solve the distribution network reconfiguration problem for active power losses reduction is presented. MATLAB R2010a was applied as a computational tool to realize the presented algorithm. In order to demonstrate the effectiveness of the presented algorithm, it has been tested on IEEE 33-bus and 69-bus systems whereas the other artificial intelligence techniques (genetic algorithms, ant colony search algorithms, fuzzy-reasoning approach, and selective particle swarm optimization) were used to verify its accuracy. Scientific novelty. A simplified version of imperialist competitive algorithm using the "power of imperialist" and "power of empire" terms instead of "normalized cost of imperialist" and "normalized cost of empire" ones is developed. Practical value. The proposed algorithm can be used to optimize configuration of the real large-scale distribution system trying to reduce the both active power and energy losses as well as to improve the voltage quality in the system's nodes.
