Advanced Load Flow Analysis for Unbalanced Radial Distribution System Incorporating Weather Conditions

摘要

In this paper, an advanced load flow algorithm is prepared for an unbalanced radial distribution system incorporating weather conditions. To determine the exact power losses and to enhance the efficiency of unbalanced load flow solutions, the effect of ambient conditions of branch resistance is considered. This attempts to incorporate the weather conditions while solving unbalanced radial distribution systems. The proposed algorithm has been tested on 25-bus and 19-bus unbalanced RDS. The results are compared with conventional load flow analysis of unbalanced radial distribution systems, and a noticeable change in the power loss, resistance and node voltages was observed when impedances are considered as a fixed parameter than weather sensitive.
