Optimal Capacitor Placement In Presence Of Distributed Generations For Optimal Management In Distribution networks

In this paper, the problem of active and reactive power losses and voltage profile improving in distribution system with the installation of distributed generations and capacitor banks is considered. By installation DGs in distribution systems, different objectives can be pursued. The main objective of this paper is reducing the active and reactive power losses, and also improving the voltage profile. In this paper, the sensitivity analysis is used to optimize the placement of DG. to reduce the search space and more influence on the voltage profile. This method is applied on candidate buses. Also, to optimal sizing of DG, the plant growth simulation algorithm (PGSA) is used. In this paper the capacitor placement method has been used to improving the voltage profile and reducing the power losses. For optimal placement of capacitor banks, the ETAP software is used. To evaluate the effectiveness of the proposed method, this method, tested on the 33-bus IEEE test system and the results are satisfying.
