Frequency and Voltage Control of Multi-Area Multisource Power System Using Whale Optimization Algorithm

The stability of terminal voltage and nominal frequency in an interlinked power system (IPS) is a foremost challenge. The active and reactive power requirements are impacted by load fluctuations or other disturbances, which has a negative impact on how well IPS functions normally. In order to keep the terminal voltage and frequency at their recommended levels, Tie-line is used to connect the loops of the automatic voltage regulator (AVR) and load frequency control (LFC). In this work, a control methodology based on a 2DOF-PID and PIDA controller is used in a multi-area IPS in mutual LFC and AVR. The optimal parameters of 2DOF-PID and PIDA controller were obtained using Whale Optimization Algorithm (WOA). The simulation outcomes of WOA-2DOFPID and WOA-PIDA control schemes were matched with recently developed nature-inspired computations. In addition to LPBO-PIPD, AOA-PIPD, and MPSO-PIPD, the suggested control schemes WOA-2DOFPID and WOA-PIDA are clearly more reliable, as evidenced by the comparison of the controllers.
