Reduce power system losses and improve voltage profiles using PSO algorithm in the presence of distributed generation units.

One of the most effective methods to respond to load growth and also to provide a certain level of reliability is the use of DG dispersed products. Several technologies can be used as DG resources. Such as photovoltaic cells; Wind turbines; Combustion engines; Fuel cells and... Power factor correction means that the reactive power required by the load is generated near the load instead of from the mains. The construction of a capacitive bank at the load site is a suitable way to modify the power factor. In this paper, the aim is to optimally position and measure the DG and capacitor (simultaneously and independently) in a radial distribution network. By properly considering the objective function, the problem is solved in a multi-objective way with the help of a particle swarm algorithm. The simulation results are evaluated on the ۶۹-bus IEEE standard network and the effect of the presence of DG and capacitor in the network is investigated.
