摘要

Excessive utilization of distributed generation (DG) leads to power quality issues in the radial distribution system (RDS). The harmonic level exceeds the IEEE-519 standard limits if DG penetration level extends. In this paper, the impact of DG penetration on the optimal placement and sizing (OPAS) of active power filter (APF) is discussed. The new nonlinear load position based APF current injection (NLPCI) technique is proposed to locate the feasible buses for the placement of APF in presence of nonlinear load only as well as in presence of DG also. Here, the grey wolf optimizer (GWO) is used to recognize the optimal size of APF. The result shows that the size of APF required with inclusion of nonlinear load and DG is bigger as compared to that with nonlinear load only. The GWO outcomes are compared with the results of particle swarm optimization (PSO) and harmony search (HS). The result shows that penetration of DG affects the placement and size of APF, and GWO gives significant outcomes compared to PSO and HS.
