Improved performance network reconfiguration in coordinated planning in radial distribution system considering harmonic distortion

– This research deals with the development of a network reconfiguration on a radial distribution system in coordinated planning in the form of a combination of optimization techniques for DG placement, capacitor placement and network reconfiguration simultaneously in order to minimize losses, THDv and voltage deviation considering the spread of harmonics due to nonlinear loads. Particle Swarm Optimization (PSO) Method from previous researches is used in this research. The IEEE 33-bus test standard radial distribution system is tested in several MATLAB-based case studies in order to find optimal results, and this method is compared with the Simulated Annealing and Firefly Algorithm. The results obtained indicate the effectiveness of the approach using the PSO method in finding the objective function with predetermined limits.
