Planification des réseaux de distribution en présence de la production décentralisée

Abstract

Given the widespread number of users from the mains and also the increase in network load, the electricity distribution companies attempt to provide the energy required by good design and operation of the network .With regard to the widespread use of distributed generation or distributed in the distribution network , technical impacts in the distribution system must be carefully analyzed. In this paper , decentralized production and capacitors are placed simultaneously optimally at the radial distribution network and for different load levels , with the aim to reduce the total loss of active and reactive power and reduce losses energy . And the effect of capacitors and decentralized production on improving the voltage profile has been considered in this paper. An optimization algorithm known algorithm Firefly or Fireflies is used to find optimal solutions. This is a new meta-heuristic algorithm mimicking the social behavior of fireflies flying in the sky summer tropical and temperate. The performance of the proposed algorithm is evaluated on three tests of distribution networks. Key-words: Distribution networks, shunt capacitor, optimization of the compensation, power factor.
