Considerable number of procedures are presented regarding sale and payment structure in power markets. However, the proper analysis of these mechanisms have proved challenging. Offer Cost Minimization (OCM) procedure was previously proposed for addressing this issue that conducts minimization of the cost evaluation by locational marginal prices. The Payment Cost minimization (PCM) structure was proposed recently that carries out direct payment minimization of the consumer and is more sophisticated than OCM in aspect of structure, transformation to single-level linearized optimization problem and computational burden. In this work, a new stochastic search algorithm was proposed for minimization of the payment via dealing with the joint energy-reserve in PCM problem which the time limit of 15 minutes was set to stop the branch and cut model. By application of proposed algorithm to the PCM problem and OCM, 174 second for OCM and 133 second for PCM problems have been obtained. Also, by considering the reserve problem the solution time was about 37 seconds and 15 minutes for OCM mechanism and PCM mechanism, respectively. The proposed algorithm is tested over different benchmark function (CEC-2013 testbed) and a real-world engineering problem. Obtained results are compared with conventional model based OCM over different case studies
