The retail electricity market is the intermediary between end-user customer and the wholesale market to supply customers’ energy. One of the basic tools in interaction between the retailer and the end-user customer is use of demand response programs. In this research, a business-economic model with the aim of maximum interaction between retailer and other electricity market players based on interval optimization and demand response programs is proposed to achieve an optimal decision of retailer in bilateral contracts and the pool electricity market. This proposed model calculates the retailer's profit before and after the implementation of appropriate demand response program and ultimately maximizes the difference between these two values. The results show that by using price-based demand response programs and price elasticity of each customer, maximum participation of customer in reducing peak load of the power grid can be achieved. On the other hand, based on proper modeling of uncertainties such as price elasticity and pool electricity market prices, the retailer's profit will increase with a suitable level of risk. For retailer profit, it can be concluded that based on application of fuzzy and epsilon constraint method, determining an optimal pareto points and retailer profit maximization will occur in real time pricing tariff compared to time of use pricing tariff . From the maximum interaction point of view between the retailer and the end-user customer in the electricity market based on the current research, the preferred policy is the policy of using intelligent methods of price-based demand response programs.

Various studies in electrical energy markets show that the active participation of the demand side in the electricity market, under the title of participation in demand response programs, leads to lower electricity prices, elimination of transmission line density, increasing of network security and improving the liquidity of the market. Accordingly, and in order to get the most out of these programs, it is first necessary to provide an economic model and use it to increase the willing of clients to participate. In this study, a simulation of a economic model of demand response has been performed based on price elasticity of demand and utility function. Since the demand of electricity depends on various elements of decision, such as the price of electricity, level of participation, the value of incentives and penalties specified in the demand response plans, it has been attempted to simulate them in an economical proposal. The proposed model has been evaluated using data related to the city of Tehran. And the results of the simulation have been presented in different scenarios. The results show that time-based rate programs are not sensitive to elasticity, and in any case, changing elasticity is not a determining factor in choosing the optimal policy for market decision makers, and only by changing elasticity, technical and economic indicators can be improved. But incentive-based programs and combined programs are sensitive to elasticity, and changing elasticity, in addition to improving technical and economic indicators, is a determining factor in choosing the optimal policy for market decision makers.
