Description: A distribution system is an interface between the bulk power system and the consumers.
Among these systems, radial distribution systems are popular because of low cost and
simple design. In distribution systems, the voltages at buses reduces when moved away
from the substation, also the losses are high. The reason for decrease in voltage and high
losses is the insufficient amount of reactive power, which can be provided by the shunt

Description: Production of energy in centralized power plants
and transmitted via transmission lines to the customers is
always with high power losses. Distributed generation
(DG) especially renewable energy resources (RES) and
energy storage systems (ESS) through distributed system
are very cost saving and sometimes inevitable. If these
small DGs want to connect to power system and participate
in energy market directly, both distribution and energy
market would have many problems with control such a high amount of information and small supplies of DGs. Application of virtual power plant (VPP) as an aggregation of some DGs with own local energy management system and some fix and variable loads is a suitable solution for DGs and networks problems.

Description: In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased. The sizing and placement of DGs in the system must be optimal because a wrong choice has a negative impact on the system behavior. To solve this combinatorial problem, an algorithm known as Firefly algorithm is proposed in this paper. This is a meta-heuristic algorithm inspired by the behavior of fireflies flashing. The main objective of firefly flash is to act as a signaling system to attract other fireflies. Networks tested IEEE69-bus and IEEE33-bus are used to evaluate the effectiveness of this method. The results are compared with those obtained by genetic algorithm (GA) to IEEE69-bus, and Shuffled frog leaping algorithm (SFLA) for IEEE 33-bus. Platform: |

Description: Power distribution systems have tie and sectionalizing switches whose states
determine the configuration of the network. Reconfiguration of distribution network
is achieved through switching operation switches of distribution network branches.
Power companies are interested in finding the most efficient configuration for
minimization of real power losses and load balancing among distribution feeders to
save the energy and enhance the operation performance of distribution system.
The objective of this thesis is to show that the ant colony optimization
algorithm can be used successfully in the reconfiguration of electrical distribution
networks to minimize the power losses of the system and to balance the loading of the
feeders. This work is to provide a basis for power companies to use it in the
reconfiguration of the distribution networks to reduce the operational costs and to
