Identification of optimal location for placing distributed generators for the mitigated power losses and upgraded voltage profile in radial distribution network is presented in this article. Load flow solution is obtained using Backward-forwardsweep method. Improved Binary Bat algorithm, as optimization technique, is used to evaluate the possible best location and magnitude of dispersed generators. Analysis is done by simulating over IEEE-33 and IEEE-69 bus system. Results signifies the loss reduction with voltage profile improvement.

This paper presents an algorithm for solving the power flow (PF) problem of droop-regulated AC microgrids (DRACMs) operating in isolated mode. These systems are based on radial distribution networks without having a slack bus to facilitate conventional computations. Moreover, distributed generation units have to distribute the power and voltage regulation among themselves as a function of operating frequency and voltage droop rather than having a slack bus that regulates voltage and power demands. Based on the conventional backward/forward sweep algorithm (BFS), the proposed method is a derivative-free PF algorithm. To manage the absence of a slack bus in the system, the BFS algorithm introduces new loops, equations, and self-adaptation procedures to its computation procedures. A comparison is presented between the proposed BFS algorithm and other state-of-the-art PF algorithms, as well as PSCAD/EMTDC. In comparison to existing algorithms, the proposed approach is fast, simple, accurate, and easy to implement, and it can be considered an effective tool for planning and analyzing islanded DRACMs.

This study presents an efficient power flow method for analysing distribution systems. The proposed method utilises efficient quadratic-based (QB) models for various components of distribution systems. The power flow problem is formulated and solved by a backward/forwardsweep (BFS) algorithm. The proposed QBBFS method accommodates multi-phase laterals, different load types, capacitors, distribution transformers, and distributed generation. The advantageous feature of the proposed method is robust convergence characteristics against ill conditions, guaranteeing lower iteration numbers than the existing BFS methods. The proposed method is tested and validated on several distribution test systems. The accuracy is verified using OpenDSS. Comparisons are made with other commonly used BFS methods. The results confirm the effectiveness and robustness of the proposed QBBFS at different conditions.
