This paper focuses on the modeling of wind turbines equipped with direct drive permanent magnet synchronous generators for fundamental frequency power system simulations. Specifically, a procedure accounting for the system active power losses to initialize the simulation starting from the load flow results is proposed. Moreover, some analytical assessments are detailed on typical control scheme...

An autonomous microgrid is often formed by incorporating distributed generators into the distribution system. However, have less inertia compared to traditional synchronous generators, and can cause system frequency become unstable. Additionally, as more clusters are integrated microgrid, instability increases. To resolve in cluster, this study proposes a supercapacitor control approach. The co...

In this paper, a novel approach to control a single generator, connected to an infinite bus, is presented. Modifying published results for nonlinear identification using recurrent neural networks, a block controllable neural identifier is proposed, based on this neural model a control law is derived, which combines sliding modes and block control. The neural identifier and the proposed control ...

Wind energy development is consumer and environment friendly, it requires shorter construction time compared to thermal, nuclear generation and is cost competitive. It becomes one of the most competitive sources of renewable energy. However, wind power has some disadvantages. For example, wind power is considered an intermittent power supply because wind does not blow 100% of the time. Besides,...

Because of the development of electric power industry accurate analysis of incipient faults in generators becomes very important. This paper presents a method for simulating the internal faults in synchronous generators using artificial intelligence technique. The internal faults like single line to ground, double line to ground & triple line to ground of generator stator current, rotor speed, ...

A novel application of Artificial Neural Network (ANN) to estimate and track Hydro Generator Dynamic Parameters using online disturbance measurements is presented within this paper. The data for training ANN are obtained through off-line simulation the generators modelled in a one-machine-infinite-bus environment parameters sets that representative practical data. Levenberg-Marquardt algorithm ...

The use of doubly fed induction generator in wind power plants has result in new necessities to maintain a reliable operation of the network. The tendency of the grid codes is to require the ability from the wind power plant to keep connected during and after grid disturbance, similarly to the synchronous generators requirements. This paper analyse the behaviour of a wind power plant equipped w...
