Delay - Dependent Stability Analysis of Load Frequency Control Systems Considering Wind Power Participation
(IEEE, 2024) Gul, Kubra Nur; Sonmez, Sahin; Ayasun, Saffet
This study presents the delay-dependent stability analysis of the load frequency control (LFC) system enhanced by dynamic participation of wind turbine (WT). The development of the energy conversion technologies in the variable speed WTs provides the inertia support based on rotational kinetic energy and primary frequency reserve for the grid. However, the extensive utilization of communication networks to exchange data for managing and control of generation units causes the network-induced delays which negatively affect the frequency stability of the system. In addition, the LFC-WT systems face with the parametric uncertainty issue due to increasing the complexity of the LFC system and uncertainties in the WT. In this regards, the study aims to obtain the stability delay margins of the LFC system with WT deloading operation by time-domain simulation and Kharitonov theorem. The obtained stability delay margins are verified by Quasi-Polynomial mapping Root (QPmR) finder algorithm. The obtained findings show that the integration of WT including inertia control and deloading control loops into LFC system improves the delay margins and robustness of the system.
