Impact of Rooftop PV Integration in Distribution Systems Considering Socioeconomic Factors

This paper presents a methodology to realistically assess the impact of rooftop photovoltaic systems in large-scale distribution networks. The proposed methodology sensibly assigns a photovoltaic capacity and probability of installation to each customer in the network before running the impact assessment. The study makes use of geographic information systems to model the network in detail, including hundreds of secondary systems and thousands of residential and commercial customers. Extensive simulations with different photovoltaic penetrations show that, contrary to simplified adoption models, the proposed methodology can capture the effects of clusters of customers with high probability of installing photovoltaic systems.
