摘要

The integrated study of automatic voltage regulation (AVR) and load frequency control (LFC) in a two-area hybrid power system is examined in this research. A new Moss Growth Optimization and Artemisinin Optimization (MGO-AO) algorithm is suggested for the best controller parameter tuning, while a traditional FOPID controller is used as the secondary controller. First, a test system with two-area non-reheat thermal turbines is used to apply the MGO-AO algorithm. The analysis of the joint LFC-AVR problem is then expanded to a combination model. In addition, a high-voltage direct current (HVDC) link is added to the system in addition to the traditional AC tie-line. A battery energy storage system (BESS) is also incorporated to reduce frequency and voltage fluctuations and enhance system stability. When compared to an AC-only network, the AC/DC hybrid transmission system dramatically improves system dynamic performance, according to comparative studies. Robustness is demonstrated for representative disturbances e.g., \(\:3\text{\%}\) and \(\:5\text{\%}\) step load perturbations in the two regions and a \(\:5\text{\%}\) generation loss with a \(\:3\text{\%}\) generation increase and for configurations with and without BESS. Comparative analysis against ARO, GWO-PSO, modified SSA, and the standalone MGO and AO shows that the proposed hybrid MGO-AO/FOPID achieves the lowest settling times and overshoots. Hardware-in-the-Loop (HIL) validation on dSPACE MicroLabBox confirms the practical implementability of the unified FOPID scheme.
