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 ...
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 ...
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 ...
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 ...
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 ...
A Prototype Mobile Expert System for Nutritional Diagnosis
(2013)
This paper describes NUTRITION UCR, a prototype expert system for human nutritional diagnosis developed in Java on Android using a service-oriented architecture. The system runs on mobile devices and offers smart features ...
