Optimized damping for LCL filters in three-phase voltage source inverters coupled by power grid
Journal of Modern Power Systems and Clean Energy, 2017 The application of LCL filters has become popular for inverters connected to the power grid due to their advantages in harmonic current reductions. However, the power grid in a distribution system is non-ideal, presenting itself as a voltage source with ...
