Aligning regulatory incentives and price signals in the Brazilian wholesale and retail electricity markets
Managing electricity supply and demand for electricity in Brazil is particularly challenging because of the great variability of supply and demand. The variability of supply is due to the stochastic nature of renewable ... -
Minimax approaches to optimal transmission expansion planning considering non-probabilistic scenarios of market-based renewable generation capacity additions
This paper investigates the potential of minimax-cost and minimax-regret approaches for centralized & determinative transmission expansion planning under uncertainty regarding market-based generation expansion, ... -
Explorative ex-ante consumer cluster delineation for electrification planning using image processing tools
The ex-ante division of consumers into potential off-grid and grid-extension clusters represents a crucial input to electrification planning. This paper explores the application of image processing tools to distinguish ... -
On the emerging role of spatial load forecasting in transmission/distribution grid planning
Spatial load forecasting methodologies spatially allocate expected electricity demand growth in a study area. In the last decades, this kind of forecasting has been applied to backup traditional transmission and distribution ... -
Comparison among deterministic methods to design rural mini-grids: effect of operating strategies
Mini-grids are well known to be a suitable solution to foster rural electrification in developing countries, and yet risks and high costs are hampering their spreading. Even though effective tools can help developers to ... -
Vertical load uncertainty at the T/D boundary under different spatial DER allocation techniques
Vertical load is the power flow between electrical transmission and distribution networks. In the past, large-scale generators connected to transmission systems supplied consumers connected to lower voltage levels across ... -

Optimal design of off-grid power systems operated by a rolling-horizon strategy: a method to reduce computational requirements
Reducing costs and risks to foster rural electrification in developing countries is one of the major hurdles for researchers, firms and practitioners aiming to develop business with rural minigrids, which are local networks ... -
Enhanced brain death diagnosis through teleneurology
Background: Brain death determination requires expertise and in some cases leads to additional medical procedures that may not be available everywhere. It also generates a great amount of distress for patients and their ... -
Identifiability matters: a closer look at the art of simple mathematical models for complex systems
Mathematical is a valuable tool in Immunology, enabling us to understand complex mechanisms at different scales and make predictions about their behaviour. However, designing a model that accurately represents a system can ... -
Damage clasification in composite materials using neural networks
Composite materials are widely employed in critical industrial applications, where their use has surged due to their numerous advantages over traditional materials. However, these benefits can be compromised if adequate ... -
