To the inverse, disorganized and non controlled introduction of these systems would lead to stroke on verse deterioration more and more increased from PQ. In this research, it is intended to introduce a simplified method as according to existing topology and space-temporal distribution of loads, it would allow the energy system operator to know active and reactive powers potential margins to inject at the network in order to reduce losses and to improve the level voltage. The gait adopted in this research is based on insertion of production Distributed Generation (DG) in various positions with application and verification on the East Algerian zone electrical network.
