Аналіз режимів роботи замкнених електричних мереж з джерелами розподіленої генерації

Abstract

Owing to increase of a current consumption, the electric system is appeared on the verge of excess for rated loading. At the same time, tendencies of last decade have shown that the problem of full-scale modernization of power branch is open and the network companies are forced to work with the equipment which has almost exhausted the resource. Taking into account it, the economy of electropower branch starts to prefer sources of the distributed generation [1'3] which are integrated into distribution network. Now there is no possibility of exact definition of the electric power losses in conditionally closed circuits, because energy overflows between mutual spare circuits both in normal and in emergency conditions are not taken into account. Therefore, circuits’ state optimization of the distributive electric system becomes a problem question. Its solution will allow using available power capacities more effectively.
