In this paper, the methodology used for optimal placement and best sizing of distributed generation units is particle swarm optimization algorithm. The objectives include improvement of voltage profile using voltage profile improvement index and congestion management using locational marginal price approach. In order to reduce the congestion, the difference of the locational marginal price between various buses is reduced. The IEEE 14 bus system is presented to represent the usefulness of the particle swarm optimization with locational marginal price-based approach as an objective function in relieving congestion and improving voltage profile. In this paper, voltage criteria-based approach is used to improve the voltage profile of the system and locational marginal price-based approach is used to reduce the congestion by using particle swarm optimization.
