Wind power technology has been developing widely in recent years. Several research fields in power systems such as prediction of wind speed, wind generator system modeling, system stability and control of wind energy conversion system are emphasized further with the consideration of wind power. With increasing penetration level in power system, the issue concerning the influence of wind power o...

It is important to improve the accuracy of wind speed forecasting for wind parks management and wind power utilization. In this paper, a novel hybrid approach known as WTT-TNN is proposed for wind speed forecasting. In the first step of the approach, a wavelet transform technique (WTT) is used to decompose wind speed into an approximate scale and several detailed scales. In the second step, a t...

Wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. Owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. In general, these wind power plant...

In a wind farm, the wakes formed by upstream wind turbines decrease the power outputs of downstream wind turbines by reducing wind speed. This wake interference significantly lowers the power production of a wind farm, especially that of a large-scale wind farm. In this paper, we express wind farm power as a differentiable function of location variables. We then apply a sequential convex progra...

Reducing fossil energy resources and increasing greenhouse gases necessitate the need of clean sources of energy. One of the sources of renewable energy is wind power which has been developed in recent years. Sometimes, wind power in peak hours does not respond. Hence, a storage system and backup power for such power plants seem necessary. In this study, a hybrid system, consisting of electroly...

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...

Wind energy conversion systems are very different in nature from conventional generators. Therefore dynamic studies must be addressed in order to integrate wind power into the power system. Angular stability assessment of wind power generator is one of main issues in power system security and operation. The angular stability for the wind power generator is determined by its corresponding Critic...

A wind farm is a collection of wind turbines built in an area to provide electricity. Wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. In this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in HL1 level is proposed. In proposed procedure, application of Fuzzy – Markov f...
