STUDI OPTIMASI LOKASI PENEMPATAN PEMBANGKIT DG TIPE GENERATOR SINKRON PADA SISTEM DISTRIBUSI DENGAN METODE FLOWER POLLINATION ALGORITHM (FPA) = Optimization Study of DG Placement Location of Synchronous Generator Type in Distribution System with Flower Pollination Algorithm (FPA) Method

In power systems, the increase in demand for electrical energy by consumers has exceeded the capacity of grid-connected generators which negatively affects system reliability and the quality of electricity received by consumers. One proposed solution to address this challenge is through the use of distributed generation (DG). Many studies have been conducted to optimize DG placement to improve power distribution efficiency. One artificial intelligence method that shows potential is the flower pollination algorithm (FPA). In addition, the application of type 3 DGs, which have the ability to inject active and reactive power into the system, has proven successful in reducing power losses and improving voltage profiles. The analytical results of this study indicate that the placement of single or multiple type 3 DGs on an IEEE 33 bus radial distribution system results in a reduction in active power losses of 64.73% to 92.86%, and a reduction in reactive power ranging from 59.58% to 91.3%, while achieving a minimum voltage at 0.9636 pu. In a similar scenario in the IEEE 69 bus distribution system, the placement of single and multi DG type 3 resulted in a reduction in active power losses of approximately 52.845% to 84.98%, and a reduction in reactive power losses ranging from 47.88% to 75.33%, with the minimum voltage reaching 0.9668 pu. This study explains that the placement of type 3 DGs can effectively reduce active and reactive power losses, while improving the voltage profile in the distribution system.
