Optimal of shunt capacitor placement and size in Algerian distribution network using particle swarm optimization

The integration of shunts capacitor in the distribution system can have significant effects on the behavior of the system. An improper insertion of this equipment can cause negative impacts, the solution of these impacts requires an optimal location of shunt capacitors with adequate power injected. The main objective of this study is to determine the optimal placement and size so that the maximum annual benefit due to peak power and reduce energy loss, compared to the cost of installation be minimal. So it is necessary to use optimization techniques that we used the Particle Swarm Optimization (PSO) algorithm to solve this problem. The technique has been validated and tested on different types of distribution network including three IEEE standard networks (10 bus, 15 bus and 34 bus) and applied on a real network of Algerian distribution system.
