  7. Abstract:
  8. After restructuring in power systems, Independent System Operators (ISO's) are looked for an appropriate auction mechanism to find the market operation point. In deregulated electricity markets, Offer Cost Minimization (OCM) auction is used to minimize the total bid cost for selecting offer and demand bids. But a uniform market clearing price (MCP) or Locational Marginal Price (LMP) is used for consumer payments. Hence, the minimized bid cost is different from settlement cost. The used mechanisms are for manufactures offer and their cost functions optimization. The Payment Cost Minimization (PCM) is one of the mechanims that affect directly on the consumers payment and lead to reduction of the payment costs. Besides this mechanism, simultaneously association of the conusmers in auction market using the Demand Response programs lead to electricity price reduction, transmission lines congestion resolving, security enhancement and improvement of market liquidity. Purpose of this research is the presenting of an appropriate mechanism for minimization of consumers payment costs and determining the on/off state of units in the mechanism. This study consists of simultaneously implementation of Unit Commitment (UC) program and Emergency Demand Response Programming (EDRP) and Interruptible/ curtailable loads (IL) to reduce payment costs, flatness of the load curve and increase the system reliability
