Fault Location Estimation in Smart Grid

Abstract

This thesis presents a proposed method for fault location estimation within the transmission grid using different optimization algorithms. An introduction on fault types is presented and illustrated with the concentration on the fault location estimation problem.

Fault location estimation problem is a very crucial one affecting the reliability and continuity of energy supplied to different customers, considering that transmission system is the most exposed system to different types of faults.

Then a literature survey took place mentioning many algorithms used for this purpose and illustrated the theory behind each of them.

The next part shows different case studies and different algorithms were used and compared to reach the best fit from the accuracy and execution time point of view.

The last part shows an illustration of the proposed method of fault location estimation accompanied by the obtained results, curves and graphs when applied to the case study.

Finally, a general conclusion with a recommendation for future work to enhance the presented method, in addition to ways of as well. Key words:

1- Fault Location. 2- Genetic Algorithm. 3- Harmony Search 4- Casue- Effect. 5- Optimization Technique.
