Optimal Power Flow the Sulselrabar 150 KV system before and after the penetration of wind power plants considering power loss and generation costs

Abstract

Optimal Power Flow (OPF) is to optimize power flow in interconnection systems to decrease production costs and increase system reliability, quality, and stability. This research was conducted on power generation 150 KV systems in South Sulawesi, Southeast Sulawesi, and West Sulawesi, abbreviated as Sulselrabar. The number of buses is 44, 15 generator buses before penetration with the Sidrap Wind Power Plant (PLTB), and 16 bus generators after penetration with PLTB. The method used in this study is Improved Particle Swarm Optimization (IPSO) and Lagrange. The results showed that IPSO showed better results compared to Lagrange and the results of existing systems.
