With the development of deregulated power systems and increase of prices in some hours of day, demand side management programs were noticed more by customers. In restructured power systems, DSM programs are introduced as DEMAND RESPONSE. In this paper it is tried to evaluate the effect of DR programs on power system reliability and local marginal price. In order to reach to this target, Direct Load Control program, as the most common demand response program, is considered. Effects of demand response programs especially direct load control (DLC) on system reliability and Local marginal price of a deregulated power system are investigated using direct load control and economic load model, DC and AC power-flow-based optimal load curtailment objective and reliability evaluation techniques. The proposed method is evaluated by numerical studies based on a small reliability test system (RBTS), and simulation results show that demand response programs can improve the system reliability and reducedlocal marginal price spike.
