Integration of Open Source Tools for Studying Large-Scale Distribution Networks
(2017)
The penetration of Low Carbon Technologies (LCTs) is expected to increase in the
near future given the attractive incentives from governments, the cost-effectiveness of the technologies
and the appearance of Smart Grid ...
A comparison of bio-inspired optimization methodologies applied to the tuning of industrial controllers
(2016-11-09)
A comparison of different bio-inspired methods is presented for the problem of tuning the
parameters of a PID industrial controller for second order plus time delay plants. The compared algorithms are representative of ...
Multi-objective optimal tuning of two degrees of freedom PID controllers using the ENNC method
(2016-10-13)
In this paper the Enhanced Normalized Normal Constrained method is applied to find the optimal tuning of second order PID controllers. This tuning takes into account both the servo and regulatory modes simultaneously, as ...

Desarrollo de un Microscopio de Efecto Túnel
(2010-11-13)
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 ...
A risk-based methodology for defining the time of intentional controlled islanding
(2015-10-05)
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 ...
Distribution Network Model Builder for OpenDSS in Open Source GIS Software
(2016-09-21)
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 ...
