Power systems are operated close to their stability limits and this increases the probability of cascading outages leading to large-area blackouts. To mitigate these phenomena, intentional controlled islanding (ICI) has ...

This paper presents a tool to automatically generate distribution network models for the power engineering software OpenDSS. The tool was developed in a free and open source Geographical Information System (GIS) software ...

This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal ...

This paper presents an algorithm to estimate lost bus voltage measurements in balanced distribution networks regulated by centralized control schemes. The objective is to feed controllers with reliable estimations of lost ...

The adoption of low carbon technologies (e.g., photovoltaic systems) is expected to increase in the near future given their contribution to reduce greenhouse gas emissions. However, high penetrations of these new technologies ...

En esta tesis se presentan los resultados de la aplicación de la técnica denominada espectroscopía de ruido Flicker para el análisis del proceso de producción del silicio poroso, un material que exhibe interesantes propiedades ...

The present thesis expands the topic of lithographic resolution improvement of poly(methyl methacrylate) (PMMA) as a positive tone electron-beam resist. The investigation used electron-beam lithography (EBL) to define ...

Incluye la investigación desarrollada para crear el primer microscopio de efecto túnel en Costa Rica. Este sistema se basa en la utilización de las propiedades de movimiento nanométrico de los materiales piezoeléctricos y ...
