Comparison of results and calculation speeds of various power system power flow methods

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.
