Development of Algorithm for Expeditious Load Flow in Radial Distribution Network

摘要

The traditional load flow (Newton-Raphson) seems to be ineffective for the analysis of the distribution system owing to the non-convergence of the algorithm. Hence, the distribution load flow (DLF) method like backward/forward sweep is preferred due to convergence capability as well as the adaptability to the radial system. However, the DLF methods are quite a time consuming as well as convergence speed is low. In view of this, the paper proposes a fast and simple to implement DLF algorithm called the FSDLF algorithm. With the proposed algorithm, bus injection to branch current (BIBC) matrix is computed easily without the need for an additional algorithm, thus making the operation fast and simple. Improvement in various performance indicators like time per iteration, convergence speed, and pertinency for realistic applications outlines the threefold contribution of the paper. The performance of the algorithm is validated using different standard IEEE-benchmark systems. Finally, from the results, it can be emphasized that the FSDLF algorithm is comparatively faster in terms of performance indicator and is effective in computing voltage profiles for distribution networks in a different scenario.
