Abstract

Transient Stability Constrained Optimal Power Flow (TSCOPF) adalah analisa untuk mencari daya optimum pada setiap unit pembangkit dengan mempertimbangkan faktor keamanan sistem. Pertambahan kebutuhan tenaga listrik yang tidak sebanding dengan pertumbuhan infrastruktur tenaga listrik menyebabkan sistem beroperasi lebih dekat pada batas kestabilan. TSCOPF menggabungkan Optimal Power Flow (OPF) dan Transient Stability Assesment (TSA). Pada suatu sistem dengan biaya pembangkitan yang paling murah karena sudah menggunakan analisa OPF, belum tentu ketika dilakukan pengujian kontingensi sistem tetap stabil. TSA diperlukan untuk memastikan sistem tetap stabil setelah ada gangguan. TSA menggunakan metode Time Domain Simulation (TDS) dan Center of Inertia (COI). Generator pada sistem dimodelkan secara multimesin dan dilihat kurva ayunan sudut rotor menggunakan TDS. Stabil atau tidak stabilnya sistem dilihat dari sudut rotor menggunakan COI. Pemecahan masalah TSCOPF ini menggunakan Oppositional Krill Herd Algorithm (OKHA). OKHA mensimulasikan sifat dari kawanan Krill merespon terhadap perubahan biologis dan lingkungan. Sistem yang digunakan menggunakan 6 generator IEEE 30 bus dan 10 generator sistem Jawa Bali 500kV 29 bus. Dari hasil simulasi menggunakan OKHA menunjukan keandalan dan keefektifan permasalahan optimasi yang tidak linear seperti TSCOPF. ================================================================= Transient Stability Constrained Optimal Power Flow (TSCOPF) is an analysis to find the optimum power in each generating unit by considering the system security factor. The rapid increase of electricity demand which not followed by growth of electricity inf rastructure causing power system tend to operate closer to the stability boundaries. TSCOPF combines Optimal Power Flow (OPF) and Transient Stability Assessment (TSA). System stability is undetermined when system with cheapest generation cost which have o ptimized with OPF analysis,being subjected with contingencies test. TSA is required to ensure the system remains stable after interruption. TSA uses Time Domain Simulation (TDS) and Center of Inertia (COI) methods. The generator on the system is modeled wi th multimachine and generator respon in the form rotor angle is beeing calculated using TDS. Instability of the system determined using COI. Oppositonal Krill Herd Algorithm is being used to solved TSCOPF problem. OKHA stimulates the herding behavior of k rill swarms responding to biological and enviromental changes. The system used 6 generator IEEE 30 bus and 10 generator Jawa Bali 500 kV system. From the simulation result using OKHA shows the robustness and effectiveness on non linear optimization problems such as TSCOPF.
