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 ...
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 ...
OpenDSS-Based Distribution Network Analyzer in Open Source GIS Environment
(2016-09-21)
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 ...
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 ...
Estimation of Lost Voltage Measurements in Distribution Networks
Estimación de medicines de tensión perdidas en redes de distribución
(2014-09-08)
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 ...
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 ...
Multivariable decoupling set-point approach applied to a wastewater treatment plant
(2016-10-21)
This paper presents a formulation for the inclusion of the second degree of freedom for MIMO system for decoupling purposes. The proposal is specially effective when combined with decentralized feedback controllers. Loop ...

Monitoring the moin beach to control morphological changes due the construction of the moin container terminal, Limon
(2016-05-10)
The Moin Container Terminal (MCT) is a project under construction that represents one of the largest investments in
Latin American port facilities. The first stage consists of a seven million cubic meter sand fill constructed ...
Use of drone technology and photogrammetry for beach morphodynamics and breakwater monitoring
(2016-05-10)
Results from the use of UAV-based photogrammetry for monitoring changes in beaches and breakwaters are presented. Main recommendations are provided on the basis of lessons learned about the collection of reliable results ...
