Abstract: Appropriate design of controllers is primarily required for load frequency control (LFC). To achieve better LFC, controller parameters need to be tuned properly. Consequently, a honey badger algorithm (HBA)-based controller is designed for LFC of an interconnected system with multiple sources in this paper. The frequency deviations (FDs) and tie-line power deviation are considered as input signals to controllers. These deviation signals measured by synchrophasor technology are transferred via communication channel. The time-delay occurring during signal transfer is compensated by Padé approximation in this work. The minimisation of sum of integral-time-absolute-error (ITAE) of deviations is considered as objective function. The performance of proposed HBA-based controller is validated under different test case scenarios of varying step load perturbations. The obtained results are compared with the results reported in literature. Time-domain simulations are presented for each considered case. Additionally, the performance of proposed controller is tested for random step load variations.
