Abstract

The theoretical part describes basic power flow methods Gauss-Seidel and
Newton-Raphson in their practical forms for solving a load flow problem. In
practical part, IEEE test 24, 48 and 72 node networks are used to compare basic
methods in terms of calculation speed: on execution of one iteration, entire
calculation and on given accuracy influence. Also is analyzed optimal acceleration
factor for Gauss-Seidel method and convergences of methods. On the end, final
conclusions are obtained after analyzing comparison results.

Keywords

calculation speed; iteration; Load Flow; Gauss-Seidel; Newton- Raphson
