Developed Analytical Technique for Optimal Placement and Sizing of DG and DSTATCOM in Radial Distribution Systems

摘要

This paper proposes an analytical technique to determine the optimal allocation of Distributed generation (DG) and Distribution static compensator (DSTATCOM) in radial distribution systems. Minimizing the power loss and improving the voltage profile are taken as the main objective functions. Power stability index (PSI) is used to determine the optimal locations of DG and DSTATCOM that identifies the candidate buses which are more suitable for connecting these devices. Sensitivity analysis is used to determine the optimal size of DGs, while the size of DSATCOM is increase gradually by step size until reach to lowest losses. The developed algorithm is validated using two standard IEEE test systems: 34-bus and 69-bus and the results are compared with other well-known techniques.
