| Summary: | This paper presents an optimized design method for an LCL filter for a grid connected photovoltaic system. This method is based on the Fast Fourier Transform (FFT) of the current and voltage which provides the current ripples thus allowing to find the LCL filter passives elements. A trick which consists of inductances fragmentation is adopted in order to reduce the volume and the cost of the filter. Then, we do an analysis taking into account the impact of our neighbors' consumption. This system is controlled by a decoupled active and reactive power control ( PQ control) using a Phase Locked Loop (PLL) for the system’s synchronization. Finally, we present and discuss the results of our simulation obtained by Matlab software (simulink and simpowersystems) in order to highlight the proposed study. |
