With the growth of electrical energy demand, providing reliable energy without interruption has become very important nowadays. Maintenance scheduling of generating units is one of the crucial factors in delivering reliable electrical energy to the vital industrial and urban loads. As number of generating units and constraints over their operation is increasing, there is growing need for developing...
Wind energy is one of the most important renewable energy sources due to its unique characteristics such as cleanliness and availability. Since wind blow swings have major effects on voltage levels and active and reactive powers of wind turbine generators, it is of vital importance to fully analyze the power system containing such generators via transient simulation with distributed generation units...
This paper describes an improved technique for identification of coherent regions. In this technique, the coherent generators are identified using a pattern recognition method called hierarchical clustering technique. This method is based on the derivation of the generators' parameters and measures distances among generators. Through measuring the generators' distances, the hierarchical clustering...
Due to development of modern distribution systems, distributed generation (DG) has become more important. Since circuit breakers are not used in distribution systems, protection of these systems has raised some problems which are mostly due to malfunction of circuit breakers and lack of coordination between them. That is, if a fault occurs, some parts of the grid may be separated from the main grid...
