Abstract

To increase power quality (PQ) in radial distribution systems (RDS) by utilizing active power filters (APFs), this research discusses the application of walrus optimization algorithms (WaOA). The main problem with the PQ is harmonics. The harmonics are added to the RDS by nonlinear loads (NLs). In this instance, together with NL at two end nodes, nonlinear distributed generation (NLDG) is additionally considered. APFs are used to decrease the harmonics to specified limits. In this instance, APFs are positioned correctly to reduce harmonics and improve PQ. WaOA is utilized to maximize the APF's size at the ideal bus location. The WaOA is inspired by natural processes and contains features that are well-balanced for both exploration and exploitation. Within limitations on inequality, optimization seeks to minimize APF's current. On the IEEE-69 bus RDS, a simulation is run to assess the WaOA's performance. Four distinct cases are examined here: a) NL+NLDG only (no APF); b) APF at bus 27; c) APF at bus 67, and d) APFs are located at busses 27 and 67. These examples are taken into consideration to examine the impact of APF sizing and location on PQ in RDS. Using the artificial bee colony (ABC) optimization method, a comparison analysis is performed. The simulation results confirm that the WaOA algorithm solves the optimization problem with stability and efficacy.

Keywords: Active power filter, Harmonics, power quality, Radial distribution system, Walrus optimization algorithm.
