Different types of permanent magnet generators for wind power application have been subject of research during last two decades. In this thesis different topologies of electrical generators have been investigated for small scale vertical axis wind turbine application. A two stage induction generator is proposed as a alternative solution with respect to the cost of such a system. However, a bigg...

This paper presents a standalone hybrid power generation system based on low speed wind energy conversion system (WECS) using a variable speed permanent magnet synchronous generator (PMSG) with battery storage and diesel generator (DG). Different types of power management strategies are presents for minimal use of DG. For each PMS, mathematical model is developed based on the power balance (bet...

This paper aims to apply a maximum power point tracking (MPPT) algorithm into a wind turbine with variable speed generator model, jointly the wind energy conversion system (WECS). There are several types of wind turbine in different configurations and their efficiencies in energy extraction are different depending on their aerodynamic designs. In general, their power efficiencies are bounded by...

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...

The residential load is one of the largest consumers electric energy in Libya that could be supplied by renewable energies. Renewable technologies and systems can a good solution to build “Zero Energy Buildings”. A zero-energy house proposed for Maqrun city. It intended use wind turbine with batteries as storage system supply demand this house.The average daily estimated 35 kWh/day. Two WECS we...

A digital H∞ controller for a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) is presented. Wind energy is an uncertain fluctuating resource which requires a tight control management. So, it is still an exigent task for the control design engineers. The conventional proportional-integral (PI) control is not ideal during high turbulence wind velocities, a...

Abstract: Currently, the electric power production by wind energy conversion systems (WECSs) has increased significantly. Consequently, wind turbine (WT) generators are requested to fulfill the grid code (GC) requirements stated by network operators. In case of grid faults/voltage dips, a mismatch between the generated active power from the wind generator and the active power delivered to the g...

Abstract Wind energy is an effective and promising renewable source to produce electrical energy. conversion systems (WECS) have been developing on a wide scale worldwide. The expansion of wind demand tends high-quality output power in terms grid integration. Due the intermittent nature energy, great challenges are found regarding WECS modeling, control, This paper introduces comprehensive revi...

This paper presents the control of a WECS (wind energy conversion system), equipped with a DFIG (doubly fed induction generator), for maximum power generation and power quality improvement simultaneously. The proposed control algorithm is applied to a DFIG whose stator is directly connected to the grid and the rotor is connected to the grid through a back-to-back AC-DC-AC PWM (pulse width modul...

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...
