This chapter deals with a design of controllers for variable-speed fixed-pitch wind turbines. The chapter begins with an introduction to wind turbine control and the detail of nonlinear models of the wind energy conversion system (WECS). Linearization around a set of equilibrium points is presented to obtain a linear parameter variable model from a nonlinear system. Open-loop characteristics fo...

Wind energy conversion systems (WECS) have become increasingly common in recent years as a result of global warming. WECS needs to release the wind through pitch control during high winds. In this study, novel method for individual (IPC) via pitching moment estimation is designed. The conventional IPC considers blade load, without keeping rotor speed at rated value. This study proposes applicat...

nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...

This paper describes the modeling and simulation of a wind energy conversion system in Matlab/Simulink environment. The wind energy conversion system consists of a wind turbine, gear box, and induction generator. The dynamic model of a 30 kW induction generator is used for performance testing of the proposed system. Simulink models of the individual components of wind energy conversion are form...

Due to the intense penetration of wind energy into power grid, grid quality and stability have become a crucial necessity in this type generation. It is context that article has just designed an Adaptive Nonlinear Control strategy applied Permanent Magnet Synchronous Generator (PMSG) 1.5 MW power, order generate good cleanly usable energy. Interestingly, robust control algorithm mainly uses Lya...

The energy cost for producing electricity via wave energy converters (WECs) is still not competitive with other renewable energy sources, especially wind energy. It is well known that energy maximising control plays an important role to improve the performance of WECs, allowing the energy conversion to be performed as economically as possible. The control strategies are usually subsequently emp...

A self tuning PID control strategy using reinforcement learning is proposed in this paper to deal with the control of wind energy conversion systems (WECS). Actor-Critic learning is used to tune PID parameters in an adaptive way by taking advantage of the model-free and on-line learning properties of reinforcement learning effectively. In order to reduce the demand of storage space and to impro...

Commercialization of wave energy will lead to the necessary deployment of Wave Energy Converters (WECs) in arrays, or wave farms. In order for projects in the United States to be approved, regulatory agencies must perform an Environmental Assessment proving little to no environmental impact. However, little is known about the environmental impacts of such wave farms. As a result, the environmen...

This paper presents a hybrid intelligent control method that enables frequency support control for permanent magnet synchronous generators (PMSGs) wind turbines. The proposed method for a wind energy conversion system (WECS) is designed to have PMSG modeling and full-scale back-to-back insulated-gate bipolar transistor (IGBT) converters comprising the machine and grid side. The controller of th...

Abstract The presented paper gives a detailed observation of the PQ related problems for WE based on EFIG or DFIG (Extra Doubly Fed Induction Generator. Fundamental Frequency Components are most typical reasons disruption power quality. On other hand, wind loading conditions also disrupt Numerous modes removing these were studied to get rid fundamental frequency components WES (Wind Energy Syst...
