The transmission networks are no longer responsible solely for security issues in low voltage distribution networks due to high penetration of distributed generation (DG) in distribution networks. Penetration of DG units in distribution network has increased rapidly, stimulated by reduced network power losses, improved bus voltage profile and better power quality. To maximize the availing benefits, optimal DG planning is necessary. Two critical issues of DG planning: (i) Optimal placement (ii) Optimal sizing. The objective of this work is to demonstrate a simple and fast technique to determine appropriate location and size of DG units. In this project DG placement problem is solved based on voltage stability technique (Modal Analysis). The Modal Analysis determines the critical modes and their associated participating buses, which lead the system to instability. The bus with the biggest participation factor in each mode is selected for allocation of DG units. The effectiveness of this methodology is tested on a well known 33-bus radial distribution network.
