Our electricity network has been plagued by power outages, which have been blamed on a variety of factors including overcurrent, overvoltage, and harmonic distortion induced by waves, to name a few. We show how an optimization strategy may be used to reduce the effects of power harmonics on our distribution transformers. The harmonic distortion data was obtained from the Power Holding Company of Nigeria (PHCN), formally known as the National Electric Power Authority, using a 500KVA distribution transformer (NEPA). The harmonic mean was determined from the harmonic distortion data obtained; optimising the mean from the collected data, training the optimised result to minimise harmonic in power distribution transformer, designing a Simulink model for mitigating the resultant effect of harmonics, which are the sinusoidal components of a complex wave, using simplex optimization technique; and designing a Simulink model for mitigating the resultant effect of harmonics, which are the sinusoidal components of a complex wave, using simplex optimization technique. When the optimization strategy is used, we get a result that is 69 percent better than the traditional method of proportional integral derivative (PID) in terms of minimising harmonics in power transformers. When the objective function was maximised under two restrictions, the result was a lower value of 14.33W, which reduced the overcurrent even further and increased the total power factor. The collected findings reveal that harmonics were decreased from 14.8333Kw to 3.7kW, indicating that improved harmonics resulted in a significant reduction in overcurrent and overvoltage, resulting in a stable power system.
