Improving AGC Performance with Hybrid Energy Storage Systems for Enhanced Utilization of Renewable Energy

This paper explores a two-area power system that incorporates hybrid energy storage (HES) for enhanced frequency regulation services. The focus is on a hybrid hierarchical control method that includes inherent communication delays, serving as a generalized load frequency control (LFC) model. A quasi-oppositional Harris Hawks Optimization (QOHHO) algorithm is deployed to optimize the coefficients for the suggested cascade tilt integral-tilt derivative (TI-TD) controller. The dynamic performance of the applied HES system is compared to a battery energy storage (BES) and a system without energy storage (WES) in terms of real-time load and renewable energy intermittency. Real-time analysis using OPAL-RT demonstrates the proposed hybrid HES-based LFC model’s effectiveness in boosting the test power system’s frequency regulation capabilities.
