ABSTRACT One of the key challenges in interconnected power systems is developing an effective control strategy to mitigate frequency and deviations caused by intermittency renewable energy sources (RESs) varying load demands. This research introduces innovative cascade featuring a PPD controller followed PI (PPD‐PI) for (LFC) two‐area system with photovoltaic (PV), wind, thermal reheat sources. The walrus optimization algorithm (WaOA) employed fine‐tune parameters both PIDn PPD‐PI controllers, goal minimizing integral time absolute error (ITAE). study first applies WaOA‐tuned PID filter (PIDn) showcase WaOA's effectiveness LFC, achieving lowest objective function value 0.3862, surpassing MFO (0.3921) GA (0.4127). robustness then evaluated under various conditions, including step disturbances, random patterns, parameter uncertainties. proposed achieves significant improvements, 36.8% reduction ITAE compared second‐best CGO‐tuned PIDn‐PI Case 2, 54.45% COA‐tuned PDn‐PI 3. To further highlight advantages scheme, analysis also includes nonlinearities such as governor dead band (GDB), boiler dynamics (BD), generation rate constraints (GRC), along sensitivity stability testing change parameters. results strongly demonstrate superior performance WaOA‐optimized over existing methods.

Power system load frequency control is a key component in maintaining the stability of power system, but integration renewable energy sources poses additional challenges this balance. Due to intermittency and unsustainability energy, new controller, 2-degree-of-freedom double integral feedback controller (2DOF-PIDF-II), proposed effectively reduce errors caused by unsustainability. In addition, an improved Sinh Cosh optimizer (ISCHO) adjust parameters 2DOF-PIDF-II according characteristics excessive parameters. The performance based on ISCHO evaluated through two-area interconnected each area containing various conventional generation units renewables units. Furthermore, nonlinearities, uncertainties, fluctuations are considered designing controller. effectiveness verified comparing its with other techniques literature optimization algorithm.
