Abstract
Load flow calculation is one of the most basic problems in power engineering. The repetitive solution of a large set of linear equations in load flow problem is one of the most time consuming parts. Load flows are calculated using the traditional method such as Gauss Seidel or Newton Raphson methods. Gauss Seidel algorithm is an iterative numerical procedure and in this method the number of iteration depends on the acceleration factor (?). Here we attempt to choose the appropriate acceleration factor (?) so as to minimize the number of iteration and get the result in minimum required time. In this paper, a Fuzzy based efficient approach with MATLAB is used to evaluate the voltages at different buses by using Gauss Seidel Method for the Solutions of Non Linear differential equations. Different areas will be highlighted wherever possible based on the author’s own knowledge and experience. In conclusion and future scenario, the trend of various methods for the analysis of Load Flow Problem along with some possible research and development areas will be highlighted.
