In this paper, an approach for optimal sizing and sitting of D-STATCOM in radial distribution network is proposed with multi objective functions of power loss minimization, voltage stability, and voltage profile enhancement subjected to equality and inequality constraints. Voltage stability index is used to pre-determine the candidate bus for optimal sitting of D-STATCOM. Genetic algorithm is proposed to determine the optimal size and sit of D-STATCOM. The performance of the proposed method is tested on the two IEEE 33-bus and 69-bus radial distribution feeders. The test systems are analyzed with different loading and sizing condition of D-STATCOM. The simulation result shows that optimal sitting and sizing of D-STATCOM in the proposed networks effectively upgrade the performance of the system.
