A simulation is carried out in Matlab/Simulink , taking into account the elements representative of the photovoltaic system connected to the grid. The PV generator is simulated under nominal operating conditions. The analyses focus on the total harmonic distortion (THD) of the current and the grid voltage level. Data Analysing collection within the stability limits enabled us to identify a threshold for the penetration rate of 8 to 10% and a maximum penetration rate of around 47%. This is justified by the voltage drop and the unconditional nature of power flows at the limits of massive injections. Injections below the determined threshold have proved to be sources of pollution for the network, while massive injections change the direction of power flow. https://pubs.sciepub.com/ajer/12/4/1/ajer-12-4-1.pdf distribution grid PV system active power reactive power THD
