Оптимальное размещение батарей конденсаторов в радиальной распределительной сети

Abstract

The increasing greatly demand leads to increase in system power losses and voltage profile disturbances. The need for more effective power distribution system has become more urgent. In this regards, shunt capacitors installation on radial distribution has always been an important research area to get the optimal allocations required for voltage profile improvement, system losses reduction and power factor correction. The developed study provides two-stages to evaluate the optimal allocation of capacitors in radial distribution system. In this paper, two stages are introduced. In the first stage, the loss sensitivity analysis with two methods is employed to select the most appropriate candidate capacitor placement. In the second stage, a novel hybrid particle swarm optimization (HPSO)algorithm is implemented to find optimal sizing and allocations of capacitors and their settings from the selected buses. The proposed algorithm has been tested on different test systems as 15-bus, and 34-bus IEEE standard radial distribution systems. Moreover, the proposed algorithm has been tested on different sizes of other radial distribution systems. In order to validate the proposed approach, the obtained results have been compared with other methods. The numerical results have been proved the capability of the proposed approach to find the optimal solutions with system losses reduction, voltage profile improvement and power factor correction. Numerical results have been evaluated by MATLAB package.
