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 ...
Integration of Open Source Tools for Studying Large-Scale Distribution Networks
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 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 ...
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 ...
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 ...
Reactive Power Limits in Distributed Generators from Generic Capability Curves
This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal ...
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 ...
