Deterministic load flow algorithm for balanced radial AC distribution systems

The developed load flow algorithm is computationally efficient, provides a good convergence property, is independent of load model, nos. of laterals and sub-laterals, nos. of buses and R/X ratio of conductors, can be used for online as well as offline applications, and in contingency. Loads, in the present formulation, have been represented as constant power. Finally, IEEE 69-bus system is used as a test system to demonstrate the effectiveness of the proposed work. The load flow results and results for critical loading condition for constant complex power load obtained for 69-bus system have been verified with the results published with other existing method and found to be in exact agreement. The convergence characteristics is analysed for various system parameters and loading conditions. The proposed distributed load flow method is superior in terms of time taken for execution when compared with six other existing methods for 33-node as well as 69-node network.
