Optimal Sizing and Placement of Capacitors in Radial Distribution Systems

Different optimization algorithms are proposed for optimal allocations and sizing of capacitors in various distribution systems. First the most candidate buses for installing capacitors are suggested using Loss Sensitivity Factors (LSF). Then the proposed optimization algorithms are employed to deduce the locations of capacitors and their sizing from the elected buses. The proposed algorithm is tested on different radial distribution systems. The obtained results via the proposed algorithms are compared with others to highlight the benefits of the proposed algorithms in reducing total cost and maximizing the net saving. Moreover, the results are introduced to verify the effectiveness of the proposed algorithms to enhance the voltage profiles for various distribution systems.
