This work presents a protection scheme based on Artificial Neural Networks (ANNs) for fault detection and location in Multi Terminal Direct Current (MTDC) systems. To perform these tasks only local signals are used communication links not required. Three different schemes ANNs evaluated (DC current samples, DC spectrum wavelet coefficients), allowing comparison between the advantages disadvantages of each one. The proposed method has been tested locations resistances four terminal MTDC...

This work proposes a new methodology for reliability/availability analysis in power substations. The proposed is based on combination of Fault Tree Analysis and Monte Carlo Simulations, which are typically used separately reliability analysis. Results show that vulnerable points can be identified the substation under analysis, thus providing useful support when deciding about preventive maintenance schedule or investment direction. solution here presented compared to conventional...

The Hydrothermal Coordination problem consists of determining an operation policy for hydroelectric and thermoelectric plants within a given planning horizon. In systems with predominance hydraulic generation, the to be adopted should specify plants, so that resources are used economically reliably. This work proposes implementation reservoir rules, using inter-basin water transfer through optimization model based on Network Flow Particle Swarm Optimization (PSO). proposed algorithm aims...
