Abstract


Abstract— This paper presents a Particle Swarm Optimization (PSO) method to solve Optimal Power Flow (OPF) problem. The proposed PSO method is used to minimize power losses in transmission line with involves two stages optimization, namely the minimization of power generation and followed by the minimization of reactive power or Optimal Reactive Power Dispatch (ORPD) in the optimization process. Then, this approach is applied to the 500 kV Java-Bali electrical power system during peak loads. Simulation results on the 500 kV Java-Bali electrical power system showed that, the proposed method is able to reduce power losses in transmission lines and also production costs amounted to 23.37 MW or 17.85% and amounted to RP 631.61 million per hour or 9.63%, respectively, compared with PT. PLN (Persero) operational data.

Intisari— Paper ini menyajikan metode Particle Swarm Optimization (PSO) untuk menyelesaikan masalah Optimal Power Flow (OPF). Metode PSO yang diusulkan digunakan untuk meminimalkan rugi-rugi daya saluran transmisi dengan melibatkan dua tahapan optimisasi, yakni minimisasi daya pembangkitan dan diikuti dengan minimisasi daya reaktif atau Optimal Reactive Power Dispatch (ORPD) dalam satu proses optimisasi. Kemudian, pendekatan ini diterapkan ke sistem kelistrikan 500 kV Jawa-Bali pada saat pembebanan puncak. Hasil simulasi pada sistem kelistrikan 500 kV Jawa-Bali menunjukkan bahwa, metode yang diusulkan mampu mereduksi rugi-rugi daya saluran tranmisi dan juga biaya produksi masingmasing sebesar 23,37 MW atau 17,85% dan sebesar Rp 631,61 juta perjam atau 9,63% dibandingkan dengan data operasional PT. PLN (Persero).
