A study of gauss seidel, newton raphson and fast-decoupled methods in load flow analysis for different loadings / Ahmad Amirul Hakimi Ahmad Sabri
Analisis aliran kuasa adalah alat penting untuk analisis sistem kuasa dalam merancang dan menjadualkan kuasa antara utiliti. Untuk melakukan analisis ke atas sistem, ia perlu mencari kuasa sebenar dan reaktif dalam talian penghantaran. Kuasa yang nyata dan reaktif juga diperlukan. Ini adalah perlu untuk menentukan kaedah mana yang sesuai dan untuk analisis aliran beban sistem. Terdapat banyak algoritma dalam menyelesaikan analisis berangka menggunakan kaedah iteratif tetapi algoritma yang paling utama yang digunakan ialah kaedah Newton-Raphson, Gauss-Seidel dan Fast-Decoupled. Matlamat projek ini adalah untuk membandingkan semua algoritma ini menggunakan beban-beban yang berlainan dan melihat salah satu daripadanya antara kaedah Newton-Raphson, kaedah Gauss-Seidel dan kaedah Fast-Decoupled untuk aliran beban dijalankan untuk mencapai masa tamat masa. Kaedah berangka: Gauss-Seidel, Newton-Raphson dan kaedah Fast Decoupled dibandingkan dengan penyelesaian analisis aliran kuasa. Simulasi dijalankan menggunakan MatlabR2019a untuk kes ujian IEEE 14-Bus, IEEE 30-Bus dan sistem IEEE 57-Bus dalam pelbagai keadaan bebanan. Keputusan simulasi dibandingkan dengan masa diambil dan pengiraan lelaran yang diambil. _______________________________________________________________________________________________________ Power flow analysis is an important tool for power system analysis in planning and scheduling a power between utilities. To do an analysis on a system, it will need to find real and reactive power in transmission lines. The real and reactive power in each is also needed. It is necessary to determine which method is suitable and for the system’s load flow analysis. There are many algorithms in solving numerical analysis using iterative methods but the most and main algorithms that were being used are Newton-Raphson, Gauss-Seidel and Fast-Decoupled method. The goal of this project is to compare all these algorithms using different load loadings and see which one of them between Newton-Raphson method, Gauss-Seidel method and Fast-Decoupled method for a load flow run to achieve less run time. The numerical methods: Gauss-Seidel, Newton-Raphson and Fast Decoupled methods were compared for a power flow analysis solution. Simulation is carried out using MatlabR2019a for test cases of IEEE 14-Bus, IEEE 30-Bus and IEEE 57-Bus system in various condition loading. The simulation results were compared in terms of number of iterations and computational time taken.
