Abstract: Over the last quarter of 20th century, many developments have been made in the power generation and major transmission networks optimization. For achieving this, digital computers have been used in the study of load flows, system stability and in optimum load allocation of generators. Until recently, concentration is confined to optimize the distribution systems, which represent some 50-60% of the overall cost of an electric power system. Often, sub-transmission and distribution systems were designed with a rule of thumb approach which can result in the system becoming more expensive. This thesis presents various methods for power loss reduction of unbalanced radial distribution systems. The base case load flow solution becomes the initial solution in realization of the algorithms presented here for transformer modelling, network reconfiguration, optimal sizing and siting of capacitors as well as distributed generators in unbalanced radial distribution systems. A simple method of three phase load flow algorithm for solving unbalanced radial distribution systems (URDS) with voltage dependent loads and detailed components modeling is presented in Chapter 2. The voltage magnitude expression is solved by storing the data in vector form with lesser memory resource. Basic electric circuit analysis is used in the algorithm.The computation is simple and efficient as the algorithm identifies the buses and branches beyond a particular bus which is required only once unlike identification of parent child buses many times in forward-backward sweep method. Accurate results are obtained with the current summation method used in the algorithm. The proposed method exhibits good convergence even for unbalanced radial distribution networks with realistic R/X ratios.
