Abstract
This paper presents the design methodology using Proportional and Integral plus (PI+ ) controllers and Proportional-Integral (PI) with Filtered Integral (PIFI) mode controller for the Automatic Generation Control (AGC) of a restructured power system. The control parameters of PIFI and PI+ controllers are optimized employing Krill Herd (KH) algorithm to achieve the optimal transient response of the two-area thermal reheat interconnected power system under various possible transactions in the restructured environment. The proposed controller, a filter was added to the integral term which decouples the effective frequency ranges between the integral and proportional terms without degradation of the integral action. It produces a phase lead in a certain frequency range without having a derivative term, enhancing the control performances and stability robustness. In this study, a sophisticate application of Hydrogen Energy Storage (HES) coordinated with Interline Power Flow Controller (IPFC) is adopted for the improvement of AGC loop of the power system. The IPFC unit is to stabilize the frequency oscillations of the inter-area mode in the interconnected power system by the dynamic control of tie-line power flow and HES unit share the sudden changes in power requirement and to maintain the power quality of distributed power resources. From the simulations results, it can be observed that the proposed controllers are implemented for AGC loop of a test system with the incorporation of IPFC and HES units to enhance the total transfer capability and decrease the line congestion and to ensure power system restoration in order to provide good margin of stability.
