A comparison of bio-inspired optimization methodologies applied to the tuning of industrial controllers
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 ...
Distribution Network Model Builder for OpenDSS in Open Source GIS Software
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 ...
OpenDSS-Based Distribution Network Analyzer in Open Source GIS Environment
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 ...
A risk-based methodology for defining the time of intentional controlled islanding
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 ...
Estimation of Lost Voltage Measurements in Distribution Networks
Estimación de medicines de tensión perdidas en redes de distribución
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
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 ...
Robustness/performance tradeoff for anisochronic plants with two degrees of freedom PID controllers
In this paper, the anisochronic model (which is able to represent both over-damped and under-damped process with the same topology) is used for the tuning of PI and PID controllers. The relationship between robustness and ...
Fractional order model identification: Computational optimization
This paper deals with the identification of fractional models with one fractional parameter. This kind of models are capable to represent an extensive range of dynamics, including overdamped and oscillatory behaviors. The ...
Development of an alternative procedure to verify “in situ” volumetric diaphragm type gas meters for residential use
Cet article montre les performances métrologiques du compteur de gaz portatif mis au point pour les mesures de volume dans le domaine, quand il fonctionne à différentes conditions à l'obtention du diplôme, mais similaires ...
