A novel approach to computationally efficient algorithms for transmission loss and line flow formulations

This paper presents a novel approach to powerful, effective and computation ally efficient algorithms for formulation and evaluation of transmission lo ss and line flow through efficient loss coefficients and distribution facto rs, respectively which are uniquely suitable for real term application. The se loss coefficients and distribution factors are generated extremely elega ntly and efficiently from the hidden treasures of an available load flow so lution with trivial computational burden. Results on few IEEE Test systems are extremely exciting which reveal that the loss coefficients evaluated at the normal operating conditions are quite robust and for all practical pur poses need not be re-evaluated for wide changes in system operating conditi ons for evaluation of transmission loss or economic load dispatch solution.
