Abstract
In this article, a new and powerful algorithm called the flower pollination algorithm is proposed for optimal allocations and sizing of capacitors in various distribution systems. First, candidate buses for installing capacitors are suggested using loss sensitivity factors and the voltage stability index. Then the proposed flower pollination algorithm is employed to deduce the locations of capacitors and their sizing from the elected buses. The objective function is designed to reduce the total cost and, consequently, to increase the net savings per year. The proposed algorithm is tested on 10-, 69-, and 118-bus radial distribution systems. The obtained results via the proposed algorithm are compared with other algorithms to highlight the benefits of the proposed algorithm. Moreover, the results are introduced to verify the effectiveness of the suggested algorithm to minimize the losses and total cost and to enhance the voltage profile and net savings for various distribution systems and different loading conditions.
