Optimal Design of LLCL filter parameters for Grid-Connected Inverter Based on NSGAⅢ Multi-Objective Optimization Algorithm
摘要
Abstract
Photovoltaic grid-connected power generation systems and grid-connected inverter usually adgot L, LCL, LLCL filter to suppress harmonic injection into the grid. Compared with the former two, the LLCL filter can reduce the influence of the harmonics near the switching frequency to the power grid to a greater extent. In this paper, aiming at the problems of complex design, large amount of calculation and low accuracy of LLCL filter parameters, a multi-objective optimization algorithm based on NSGAⅢ was proposed to optimize the parameters of the LLCL filter. Finally, the simulation results based on grid-connected inverter system show that, the parameter filtering effect designed by NSGA Ⅲ multi-objective optimization algorithm is good and the harmonic suppression ability is enhanced, which verifies the validity and superiority of the optimization design method.关键词
