Automatic Generation Control Based Sliding Mode Observer Design for Multi-area Multi-source Power Systems

Today, a multi-area power system (MAPS) has been implemented with a variety of power sources, including gas, hydro, thermal and nuclear, which will have an influence on load frequency regulation. Therefore, using the single-phase sliding mode control-based state observer (SPSMCBSO), load frequency control (LFC) of a deregulated two-area gas-hydro-thermal power system (TAGHTPS) is developed. Second, feedback control state variables are estimated using the state observer. Third, to enhance TAGHTPS performance in term of settling time and overshoot, the SPSMCBSO is designed to adjust the fundamental sliding mode control. Additionally, the SPSMCBSO is set up to totally depend on the state observer to resolve the issue with the state variable measurement. Finally, to verify the SPSMCBSO scheme, the results of the MATLAB/SIMULINK simulation are displayed and contrasted with newly established conventional control approaches.
