OPTIMAL D-STATCOM PLACEMENT METHODS IN RADIAL DISTRIBUTION SYSTEM USING SENSITIVITY APPROACHES

Abstract

The major challenge in the radial distribution network is the reactive power demand, which the system fails to meet up leading to high power loss, low voltage drop and low power factor. In order to compensate this reactive power demand, D-STATCOM installation at the candidate buses is the optimal solution. In this paper, five different sensitivity methods are analysed to examine the weak bus for optimal allocation of D-STATCOM with a fixed size of 500 kVAr. Also, in this paper multi objective has been achieved by the placement of D-STATCOM in the distribution system. The presented approach has been tested and validated on a 69-bus system and a real time 31-bus system under different loading conditions. The effectiveness of the proposed approach is the exact identification of the prior candidate nodes. The results show the robustness of the proposed methodology to solve the distribution network problems
