SMES and TCSC Coordinated Strategy for Multi-area Multi-source System with Water Cycle Algorithm Based 3DOF-PID Controller

ABSTRACT This paper attempted to assess the supremacy of designed higher-order degree of freedom (DOF) proportional(P)-integral(I)-derivative(D) (PID) (3DOF-PID) controller making use of a new meta-heuristic optimization approach of water cycle algorithm (WCA) in the study of load frequency control. For this, two test system models of dual area hydro-thermal system system and multiarea multisource systems are believed for investigative purposes. The investigation is performed by imparting the area-1 of test system models with a disturbance of 10% step load (10%SLP). Parameters of 3DOF-PID are rendered optimally over the index of integral square error. Efficacy of the presented 3DOF-PID regulator fine-tuned with WCA is demonstrated with other control schemes that have been implemented on the same test systems. Moreover, superconducting magnetic energy storage and Thyristor controlled series compensator territorial schema is implemented for the MSMA system for performance enhancement. Finally, the robustness of the presented approach is demonstrated through sensitivity analysis. Graphical abstract
