Optimal probabilistic planning of passive harmonic filters in distribution networks with high penetration of photovoltaic generation

•Computing optimal probabilistic sitting and sizing of passive filter simultaneously.•Economic analysis including loss reduction benefit and passive filter costs.•Mitigating harmonic of high photovoltaic penetration and nonlinear load.•Simulation was performed using real data and low voltage distribution network.•Both magnitude and phase angle of harmonic currents are taken into account.
