Abstract

The goal of this work is to understand the power balance on urban distribution transformers, and the changes in power capacities that may be needed in a large-scale PV deployment scenario. Hourly load demand by power transformer was estimated for a suburb of Lisbon, Portugal, from reference profiles published by the distribution grid operator, and hourly PV production was calculated using irradiance simulations from SolarAnalyst extension for ArcGIS, for building rooftops, and the LadyBug plug-in for Grasshopper/Rhinoceros, for building façades. The PV potential greatly surpasses the transformers’ capacity, suggesting that network upgrades will be unavoidable in the future.
Additionally, a storage strategy for maximization of self-consumption was investigated to smooth power ramps in the grid. It is shown that without proper management strategy, small storage capacity might lead to higher ramps, whilst larger capacity might smooth ramps when the PV production peaks.
