This paper proposes a new approach able to maximize the interface flow limits in power systems and to find a new operating state that is secure with respect to both, dynamic (transient stability) and static security constraints. It combines the Maximum Allowable Transfer (MAT) method, recently developed for the simultaneous control of a set of(More)
This paper presents a multi-objective mathematical model for optimal allocation of automated devices with protection and switching capabilities in distribution networks. A contingency simulation-based technique is used to model distribution reliability considering the protection system response to faults and the post-fault restoration, thus incorporating(More)
This paper presents a methodology to develop a Fault Diagnosis Integrated System in a Thermoelectric Generation Plant (TGP). The proposed methodology is based on three methods: Discrete Fourier Transform (DFT), Fuzzy Logic and Artificial Neural Network (ANN). The test electric system was built in BPA’s ATP/EMTP software, conformably to the needs presented(More)
This paper describes the MedFasee project aiming at the development of a phasor measurement system (PMS) prototype and its applications for monitoring and control of power systems operation. A review of the state of the art, presented in the paper, provided the starting point for the project. A PMS simulator, developed to identify functionalities and(More)
This paper presents an analytical mixed-integer linear programming model to improve reliability of distribution networks through the optimal allocation of automated switching devices. Optimal reliability is formulated as a multi-objective problem of minimizing customers' interruptions and the investment costs related to devices' acquisition, relocation and(More)
 The importance of Short-Term Load Forecasting (STLF) has been increasing lately. With deregulation and competition, energy price forecasting has become a big business. Load bus forecasting is essential to feed analytical methods utilized for determining energy prices. The variability and nonstationarity of loads are getting worse due to the dynamics of(More)
