Abstract
In this paper, an application of pelican optimization algorithms (POA) for the enhancement of power quality (PQ) using active power filters (APFs) in radial distribution systems (RDS) is addressed. The harmonics is the main concern of the PQ. Nonlinear loads (NLs) inject the harmonics into the RDS. Here, nonlinear distributed generation (NLDG) is also considered along with NL at two end nodes. By using APFs, the harmonics are minimized to standard limits. Here, APFs are placed with proper size to minimize the harmonics and to improve the PQ. The POA is utilized to optimize the size of APF at proper placement. Inspired by natural processes, the POA has balanced exploration and exploitation characteristics. Subject to inequality constraints, the optimization’s goal is to minimize the APF current. The simulation is done on the IEEE-69 bus RDS to assess the POA’s performance. A comparison study is carried out using the artificial bee colony (ABC) optimization algorithm. The simulation results validate the POA algorithm’s stability and efficacy in solving the optimization problem.
