The shift from regulated to restructured power system results in an increased competition among the electricity market. In restructured power system, the separation of transmission services from generation and distribution makes it necessary to find the contribution of power from individual generator to individual load. The power flow tracing method is used to obtain the generator power output to a particular load. The reactive power has to be maintained in order to sustain the voltage level throughout the system for reliable and secure operation. Hence the reactive power cost allocation has become imperative in the power system. In this paper, the tracing method is integrated with the optimal reactive power dispatch problem to trace the generator minimal reactive power for sustaining the real power transaction and enhancing the system security by meeting the demand. The Differential Evolution is used for optimal reactive power dispatch. The cost allocation to the generators for the reactive power service based on the opportunity cost method is obtained for 62 Bus Indian Utility Systems.

Power flow tracing based reactive power pricing scheme is presented in this paper. A method is suggested to solve the problem of bidirectional flow of reactive power. The reactive power allocated by each generator to all the load buses is found and the corresponding cost to be paid by the load to generator is calculated. Super position principle based method is used to calculate the allocation of reactive power by the generators to the loads. Costs allocated for generators are found using quadratic cost function. The method is implemented on IEEE standard bus system and the results are found satisfactory.
