چکیده:
Due to the expansion of free markets of electrical energy, the use of Distribution Generation
(DG) units is increasing to provide power in distribution networks. The impact of dispersed
productions on losses and the distribution network at the average pressure voltage is the main
subject of this research. DG has many beneficial effects, including minimizing losses and
operating costs, increasing the power quality and improving the voltage profile on the network.
Using the PSO algorithm is to optimization losses and reactive power network. IEC test network
includes 26 buses and 5 DG units, which has been implemented in the MATLAB software
environment.

Using the PSO algorithm is to optimization losses and reactive power network.
Many studies have been presented in the fields of voltage control and active and reactive power in the operation of distribution systems of distributed generation units, and most researches have sought a method to achieve the best response (loss reduction and improvement of voltage profile) [2].
To compensate for reactive power, the most common and widespread solution in distribution networks are capacitor banks that act as a reactive power source and, with proper voltage control, reduce losses.
Distributed generations can reduce losses by providing local supplementation; and they can be modeled as active power supplies that are able to inject and consume reactive power [6].
The load distribution algorithm is implemented in a coordinated control and determines the optimal work point using a modeled network separately for each unit of generation.
