Summary Demand response (DR) programs are effective tools to relieve power systems operational risks and will play key role in future smart grids because of emerging advanced communication and metering technologies. Enhancing power system reliability is one of the main goals of employing DR programs. This paper presents a nodal viewpoint for reliability‐based planning of DR programs. It aims to demonstrate the superiority of nodal evaluation and prioritization of DR programs to improve reliability over the global approach. Here, a sequential state‐enumeration‐based method is presented for composite system operational reliability assessment, and a multi‐segment optimal power flow approach is developed to evaluate the effects of DR programs. In addition, analytic hierarchy process is employed for global and nodal prioritizing of different DR programs. The results show that employing DR programs based on nodal prioritization can lead to higher reliability, lower costs, and greater assurance on programs implementation.
