Abstract: This paper presents real-time simulation for single area power system with demand response (DR) to evaluate the performance of controller using LabVIEW. Here the mathematical model of LFC-DR for explorations is considered with external load disturbance are given in real-time. In this, controller is checked non-real-time simulation environmental platform and transformed the controller into a real-time model controller, which is used for testing in real operating conditions. This simulation in real-time provides a rapid solution for prototyping novel functions in different types of industrial processes and devices which are to be controlled in complex system. With the controller, simulation is carried out to monitor the results, i.e., the change in frequency deviation, the response plots are obtained for 1% to 100% load disturbance. It shows better performance and superiority by using fuzzy-PID controller-based LFC-DR single-area power system has over a classical controller under different operating scenarios.
