Reactive power procurement has been identified as an important ancillary service. The cost characteristics must be able to recover the lost opportunity cost component of generator reaching the field limits and causes the decrease in its active power when the reactive demand in the system increases. The Synchronous condensers supply reactive power to maintain the voltage and reduce the burden on the synchronous generators. In this paper, the cost characteristics of reactive power support by the generator are proposed based on its capability chart. A non-linear optimization problem formulation is proposed to compute both real and reactive power nodal prices for pool electricity market model with hydro condenser. The marginal prices at each node have been determined for both real and reactive power considering the minimization of fuel cost, reactive power cost, and cost of condenser. The cost characteristics of reactive power have been determined based on the existing methods and the proposed method. The comparison of the results obtained with existing method is also provided. The results have been determined for IEEE 24 bus test system.
