Abstract
Due to the advent of modern power technology in a wide area monitoring system (WAMS), demand response (DR) will play a vital role in the development of future power grid. A number of studies in the literature have presented several advantages and applications of DR with economical and societal benefits of a power system. However, very few studies have presented the impact of intelligent DR, especially in load frequency control (LFC) with renewable resource (RR) in Smart grid (SG) perspective. The participation of DR control loop and supplementary control (SC) loop for different load variations is presented for the system under study. In this paper, an effort has been made to present the impact of intelligent DR control loop with communication delay in a single area thermal power system integrated with a wind power generation system. Furthermore, this paper introduces a linear matrix inequality with linear quadratic regulator (LMI-LQR) controller as a coordinator between DR loop and SC loop to minimize the frequency deviation caused by communication delays. The results of this study validate the feasibility of the proposed control, as well as the capability of the DR loop for the operation of LFC in SG perspective.
