Harmonic Distortion Mitigation with Single Tuned Filter in ULP Sungguminasa Using Whale Optimization Algorithm

The spread of distortion of harmonic in a distribution electricity system is a problem that can reduce system performance in terms of power quality. This can cause losses to equipment damage. This study attempts to optimize the placement and size of single tuned filters at harmonic orders 5, 7, 11, 13, 17 using the Whale Optimization Algorithm (WOA) method which has been validated in the electricity system of ULP Sungguminasa PT. PLN (Persero) with the objective function of minimizing total losses. the maximum optimization results were obtained in the form of placement and filter size at order 5 of 5081.22 kVAr on bus 83 capable of reducing total losses by up to 28.05% compared to the location and size of single tuned filters in other orders and the % THDv value was able to be reduced to the allowable limit.
