Abstract

This paper proposes vector based load flow technique for the solution of balanced and unbalanced radial distribution networks using sparsity technique. The proposed method presents a simple algorithm to solve radial distribution systems with realistic R/X ratio, which involves the evaluation of a simple algebraic expression for receiving end voltage. The algorithm uses basic principle of circuit theory, and can be easily understood. The proposed algorithm has been tested with several distribution systems and results are compared with an existing method [10]. The effectiveness of the proposed algorithm is demonstrated through three examples, two for balanced and another for unbalanced radial distribution networks.
