Optimal Allocation of Multiple Distributed Generators and Shunt Capacitors in Distribution System Using Flower Pollination Algorithm

Abstract

Optimal siting and sizing of Distributed generators (DGs) and capacitors helps in enhancing the overall performance of distribution system. A proficient method to optimally allocate DGs and shunt capacitors in distribution system is proposed in this paper. The major objectives of the work are power loss reduction, voltage profile improvement and operating cost minimization. A standard IEEE 33 bus test system with constant power load at various load levels is considered for the analysis. Optimal siting of DGs and capacitors is carried out using sensitivity analysis technique. Further Flower pollination algorithm is employed for optimal sizing of DGs and capacitors and the results are compared with few other noteworthy methods.
