Enhancement of Voltage Stability in Distribution Systems by Optimal Placement of Distribution Generator

摘要

This article presents a methodology for optimal placement of DG units in distribution networks to guarantee the enhancement of voltage profile, maximize loadability and reduce distribution system losses. The methodology aims to find the configuration, among a set of system components, which meets the desired system reliability requirements, taking into account the stability limits. Results shown in the article indicate that the proposed formulations can be used to determine which are the best buses, where the addition of small distributed generator units can greatly enhance the voltage stability of the whole system and improve power transfer capability by reducing the system power losses. The proposed methodology is tested and compared with the existing distribution system.
