Application of probabilistic three-phase load flow for electrical distribution systems with photovoltaic generators

This paper shows how to solve a probabilistic three phase load flow in radial distribution networks with photovoltaic distributed generation (PDG). Voltage regulation is one of the principal problems to be addressed. This research study applies a three phase power flow combined with the Monte Carlo method to solve this problem. Load and PDG are modeled as random variables. A case study is presented. The results obtained show the decrease of the unbalance factor due to the presence of PDG.
