Load balancing in distribution system using heuristic search algorithm

Abstract

With the increasing use of technology and automation in various fields of modern life, the electrical outage has become a major impact to complete the requirements in the daily life of most sectors like industrial, economic and even recreational. It is, therefore, necessary to have access to a reliable electrical system to ensure continuity of consumer electric consumption. Based on the above, the heuristic searching algorithm is proposed for loads balancing in an unbalanced electrical distribution network. The imbalance ratio was calculated for the network chosen for study. The heuristic algorithm is programmed using values represent the three-phase currents of 20 houses. Each house assumes to have a smart energy meter connected with some contactors used for current balancing by phases swapping. Three cases are programmed using the heuristic algorithm to study the effect of used different numbers of contactors in each house. All the cases show high performance in loads balancing and reduced the imbalance index.
