An efficient tabu search approach for optimal operation of MV distribution networks using a past evaluation of power losses

In the present, paper the problem of minimum losses operation of automated electrical distribution networks is dealt with. Automation implies that remote control of tie-switches and capacitor banks is possible. To speed the overall procedure a fast network solution method for local search algorithms is also presented. To prove the efficiency of the proposed method a tabu search algorithm has been implemented. The evaluation of power losses and voltage drop has been done using dynamic data structures for the network representation. Test results on a large distribution network are presented and commented.
