SUMMARY:

Nowadays, there is a growth in integration of small-scale photovoltaic (PV) modules to low voltage (LV) distribution systems. In this respect, several benefits can be observed from this new scenario, such as reduced distribution and transmission losses, lower polluting gas emissions and improved power quality and reliability. However, if this integration is not properly planned some power quality operational constraints can be violated such as over/undervoltage, voltage unbalance and overload of transformers. Thus, it is important to relate these power quality indicators to the system PV hosting capacity, aiming to reach correct operation of the distribution system, even for high penetration level of PV modules. Therefore, in this work, Particle Swarm Optimization (PSO) was used with the purpose of maximizing the PV hosting capacity of LV distribution systems, through the optimized adjustment of the PV systems power factor, based on the reactive power capability presented in the Standard IEEE 1547-2018. It is worth mentioning that this study was carried out taking a probabilistic approach into account, through the Monte Carlo Simulation, due to the stochastic characteristic of several variables present in the optimization model, such as the load, irradiance and PV system location and size.
The IEEE European LV Test Feeder and a real system from the city of Salvador were adopted to validate the proposed methodology.  Through the proposed method, it was possible to improve the voltage profile of the distribution systems and reduce the number of scena
