Optimal Placement and Sizing of Distributed Generation for Voltage Profile Improvement and Power Loss Minimization

Shah Jubin Rahman | Damodar Agarwal


Abstract: In active distribution network, distributed generators (DG) are integrated with the existing distribution system. It has several advantages but the most important benefits are reduction of line losses and voltage stability improvement. But, sometimes the presence of DG on the distribution system creates an array of potential problems related to safety, stability, reliability and security of the electrical system. Whether the impact of DG is positive or negative on the system will depend on the location and size of the DG. In this paper, objective function is optimal placement and sizing of the DG unit by minimizing power losses and improving voltage profile. The first method is based on analytical approach as well as artificial intelligence method (PSO). The other proposed method is Voltage Stability Index based analytical approach. Both the methods have been implemented using MATLAB 2013 software, and tested using IEEE 33-bus test radial distribution. The results obtained from the first method and the second method are compared with the results published by Nguyen Tung and Dam Xuan Dong (using Artificial Bees Colony Algorithm) [12]. It is found that the Voltage Stability Index based analytical approach gives improved results in case of power loss minimization and voltage profile improvement than the other methods mentioned.
