accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. in this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...

In this paper, the control scheme of a wind energy conversion system for remote sites using fuzzy logic is presented. Two fuzzy controllers are proposed: the first one is dedicated to the maximum power point tracking (MPPT) of a variable speed permanent magnet synchronous generator wind turbine. The second fuzzy controller has the the objective to manage both the production and the storage of e...

A wind energy conversion system (WECS) including a variable wind turbine in grid-connected mode is considered to control. In this paper, each component of WECS model is systematically presented and then the integrated overall model is validated.Regarding to nonlinear nature of WECS and the complex system structure as multiple-input multiple-output (MIMO), it is difficult to find a proper contro...

The purpose of this paper is to show the working limits of a Variable Speed Wind Turbine. The system is based on a Doubly-Fed Induction Generator and a Fixed-Pitch Wind Turbine. The machine rotor is connected to the network through an AC/AC Converter in order to allow energy recovery. Thermal, mechanical and electric limits are investigated. The study of the machine is based on a steady state m...

this study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. however due to unpredictable nature...

The objective of the paper is to develop a novel intelligent pitch control system of a 2MW wind turbine driven by variable-speed hydraulic pump-controlled system. For realizing the intelligent pitch controller, self-organizing fuzzy sliding mode control, which combines fuzzy sliding mode control and self-organizing modifier, is proposed. In order to verify the proposed concept experimentally, a...

in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...

Secure and reliable operation of complex interactive power networks poses significant theoretical and practical challenges in analysis, modeling, simulation, prediction, control, and optimization. In addition, mathematical models of such interactive systems are typically vague (or may not even exist); moreover, existing and classical methods of solution are either unavailable, or are not suffic...
