An attempt is made to develop an algorithm based on classical coordination equations for optimal reactive power dispatch in order to make it most challenging to other existing algorithms for real-time application. A set of new loss formulae for both active and reactive power losses are proposed. An innovative approach considering the concept of fictitious reactive powers is used for modelling on-load tap changing transformers. An attempt is made to consider constraints on bus voltages by expressing the bus voltages in terms of reactive power generations through distribution factors, which are developed from available load flow information using a perturbation technique. The proposed model based on classical coordination equations is tested on IEEE 14 and 30 bus test systems and the results are compared with those obtained by more rigorous methods
