This paper presents the methodology applied to determine the level of acceptable costs of a Smart Grid module, able to support combined acting of demand side management (DSM) and demand response (DR) programs. The results of the methodology use have been illustrated by case studythe simulation of one particular DSM/DR program implementation throughout the whole consumption area of Electricity Distribution Company in Serbian capital, Belgrade. The results of the research show that the implementation of DSM/DR program would be useful and profitable for analyzed case study and supposed values of input dataunit costs for each part and device of the system. In order to check the certainty of these results, a sensitivity analysis has been performed, too, changing input data within reasonable limits.
Resultsshow that proposed DSM/DR program implementation would be beneficial, even for increased prices of necessary equipment.
