    • A comparison of bio-inspired optimization methodologies applied to the tuning of industrial controllers 

      Céspedes, Macarena; Contreras, Mónica; Cordero, Joaquín; Montoya, Gustavo; Valverde, Karen; Rojas Fernández, José David (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 

      Fernández Porras, Pablo; Panteli, Mathaios; Quirós Tortós, Jairo (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 

      Quesada, Pablo; Argüello Guillén, Andrés; Quirós Tortós, Jairo; Valverde Mora, Gustavo (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 

      Argüello Guillén, Andrés; Valverde Mora, Gustavo (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 

      Contreras Leiva, Mónica Patricia; Rivas Zúñiga, Francisco; Rojas Fernández, José David; Arrieta Orozco, Orlando; Vilanova Arbós, Ramón; Barbu, Marian (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 ...
    • OpenDSS-Based Distribution Network Analyzer in Open Source GIS Environment 

      González, Róger; Argüello Guillén, Andrés; Valverde Mora, Gustavo; Quirós Tortós, Jairo (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 ...
