SMO-Optimized Shunt Active Filter to Mitigate Harmonics in DN

Semiconductor devices play a vital role in the efficient and smart interconnection of devices in industrial and home automation. This voluminous implementation of semiconductor devices inadvertently introduces harmonics into the power distribution network. These unwanted signals result in various issues like equipment malfunctioning, power quality issues, and increasing energy losses. Various mitigation techniques are employed to reduce harmonics in the network. By implementing these mitigation techniques, the adverse effects of harmonics caused by semiconductor devices can be minimized, ensuring a more reliable and efficient operation of power systems. In this research work, a shunt active filter optimized by an SMO is used to reduce the procreation of harmonics in the 33-bus radial network. The FFT analysis is carried out using the MATLAB / Simulink model. From the results, it is clear that the %THD of SMC controlled active filter is measured as 2.79 and SMO optimized filter is measured as 2.29. Also, the time domain parameters for the 33-bus radial network are analyzed. The steady-state error of the network is outlined as 0.94.
