dc.description.abstractThis study focuses on the computation of stability regions of the time-delayed two-area load frequency control including dynamic demand response (LFC-DDR) using stability boundary locus method. With the participation of controllable responsive loads into the frequency regulation service, dynamic demand response (DDR) has become an important solution for proper balancing between generation and peak load and to overcome the intermittent nature of renewable power generations. Although the utilization of DDR control technique increases the reliability and security of the load frequency control (LFC) systems, communication time delays because of the communication networks adversely affect the controller performance and LFC system stability. Therefore, this study obtains the all stabilizing proportional-integral (PI) controller gains that guarantee the stability of the LFC-DDR system. For that purpose, stability boundary locus method is used to obtain stability regions in the controller parameters space that constitute of complex root boundary (CRB) and real root boundary (RRB) loci of the time-delayed LFC-DDR systems. The accuracy of theoretical results is verfied by an independent algoirithm, quasi-polynomial mapping root (QPmR) finder algorithm, and time-domain simulations. Results indicate that the participation of DDR control loop increases the stability regions and stability margin of the LFC system even in the presence of communication time delays.
