Abstract

This research discusses the performance of the hydraulic type Load Frequency Control (LFC) system in hydropower plants using a single controller configuration equipped with a governor against power input. The Load Frequency Control (LFC) system is used to stabilizer the power frequency during load changes by considering the influence of droop characteristics on the governor. Analysis is performed using MATLAB simulation to measure transient parameters such as rise time, peak time, steady state time, and maximum skip. The results show that the use of droop on the governor is more effective in reducing overshoot, improving system stability, but slowing down the response time. Conversely, the configuration without droop accelerates the system response but risks overshoot. Controllers with derivative components such as PD and PDF, are superior in achieving rise time. Whereas, controllers that have integral components such as PI, PID, and PIDF are better at controlling overshoot when using droop characteristics. In conclusion, the combination of droop characteristics with derivative components in the governor provides optimal performance in maintaining the frequency stability of the hydraulic type Load Frequency Control (LFC) system.

Abstract

This study evaluates the transient performance of a hydraulic Load Frequency Control (LFC) system configured with a single controller and without a governor. The analysis focuses on rise time, peak time, settling time, and overshoot, using various controllers including PI, PD, PID, PDF, and PIDF. Simulation results indicate that eliminating the governor significantly enhances system responsiveness and reduces overshoot, particularly when using the PDF controller. Quantitative analysis shows that the PDF controller achieves 85% faster rise time (0.101s vs 0.607s for P controller) and maintains system stability with minimal overshoot (1.765% for PID vs 59.263% for P controller). This configuration enables for a more direct and efficient control response to load fluctuations, improving system stability. Thus, employing a single controller without a governor presents a promising alternative for frequency regulation in hydraulic LFC systems under dynamic load conditions. The findings of this study offer valuable insights for optimizing controller selection and configuration in practical implementations, providing guidance for engineers and researchers to enhance grid reliability, operational efficiency, and stability in various real-world hydraulic power system scenarios.

Abstract

This study aims to design and analyze a Load Frequency Control (LFC) system for a power plant with a reheat turbine, using PID-based controllers with various filter configurations to optimize frequency stability under load fluctuations. A series of PID, PD, and PDF controllers is implemented and tested through MATLAB simulations, focusing on key dynamic performance indicators such as rise time, peak time, settling time, and maximum overshoot. The findings reveal that PD and PDF controllers—particularly those that omit droop characteristics and incorporate filters—consistently outperform conventional PID controllers regarding faster response and improved transient stability. The integration of filters plays a crucial role in dampening oscillations and reducing overshoot, which is essential in maintaining system robustness during load disturbances. However, the study also identifies that the absence of droop control introduces limitations in achieving steady-state accuracy. Despite improvements in dynamic performance, the system continues to exhibit steady-state deviations, highlighting a trade-off between transient responsiveness and long-term stability. This underscores the need for hybrid or adaptive control strategies that combine fast response benefits with droop-based steady-state correction. The study contributes valuable insights toward developing more resilient and efficient frequency control mechanisms in modern power generation systems.
