HVDC Links for Automatic Generation Control in a Multi-Area Interconnected Power System

This research analyses how variations in multi-area power system automatic generation control (AGC) work when an HVDC system functions with an HVAC system taking into account system parameter alterations. A fuzzy logic controller serves to connect four areas through parallel HVAC/HVDC transmission link systems also referred to as asynchronous tie lines. A linear model of HVAC/HVDC becomes available for evaluation purposes while analyzing abrupt load variations in the system. The investigation uses a four-area interconnected thermal power system. A system whose dynamic performance has been improved will deliver appropriate solutions to the automatic generation control problem affecting the four-region electrical power system. The controller robustness evaluation happens through varying system parameters. The simulation output demonstrates effectiveness of this approach. Advanced Fuzzy logic controllers in MATLAB-Simulink perform dynamic system analysis both in presence of and absence of an HVDC link. The suggested system achieves better results regarding settling time and overshoot compared to the existing model.
