Bi-Directional Search Optimization: A Search Strategy to the Optimal Placement and Sizing of Distributed Generation

In this paper, a novel search algorithm, called Bi Directional Search Optimization (BDSO) Algorithm, is formulated to solve optimization problems. The algorithm is based on search in two directions. The proposed algorithm aims to find a new and better solution by moving towards the known best solution, while at the same time moving away from the known worst solution. In the first section, the algorithm is validated against the standard benchmark functions available in the literature. In the next section, the algorithm is used to find the optimal location and size for DG placement while considering loss minimization as the objective function. The results are compared against the existing literature. ANOVA test is carried out on the DG placement results. IEEE 33 bus test system is used for the study.
