Optimal Capacitor Placement in Distribution Systems by Using DPSO Algorithm

Usually the parallel capacitor are used in distribution systems with the goal of reducing power losses, improve voltage profile and etc. These goals are depends on how the capacitors are installation and to achieve them, since the capacitor placement is nonlinear problem and has some equally and inequality constraint, so in this paper the dynamic particle swarm algorithm to solve this problem with consider to the changing in load is used. The issue for the 33 bus system sample is implemented and the results are discussed.
