Design and successful operation of wind energy conversion systems (WECs) is a very complex task and requires the skills of many interdisciplinary skills, e.g., civil, mechanical, electrical and electronics, geography, aerospace, environmental etc. Performance of WECs depends upon subsystems like wind turbine (aerodynamic), gears (mechanical), generator (electrical); whereas the availability of wind resources are governed by the climatic conditions of the region concerned for which wind survey is extremely important to exploit wind energy. This paper presents a number of issues related to the power generation from WECs e.g. factors affecting wind power, their classification, choice of generators, main design considerations in wind turbine design, problems related with grid connections, wind-diesel autonomous hybrid power systems, reactive power control of wind system, environmental aspects of power generation, economics of wind power generation, and latest trend of wind power generation from off shore sites.

Voltage control and reactive power compensation in a distribution network with embedded wind energy conversion system (WECS) represent main concern of this paper. The WECS is of a fixed speed/constant frequency type that is equipped with an induction generator driven by an unregulated wind turbine. The problem is viewed from time domain responses of the system to different wind speed changes. Being disturbed by a variable wind speed, the WECS injects variable active and reactive power into the distribution network e0xposing nearby consumers to excessive voltage changes. In the FACTS-based solution approach, the Unified Power Flow Controller (UPFC) is used at the point of the WECS network connection to solve technical issues related to voltage support and series reactive power flow control.

Double Fed Induction Generator

The advancements in power electronics have supported the widespread penetration of wind energy conversion systems (WECS) in electric grids. In this context, power converters have crucial functionality in the control of active and reactive power injection, moreover they are directly related to voltage and current harmonic distortion levels, mechanical and thermal stress that are experienced by the wind turbine. Currently, several topologies have been tested in order to improve the performance and increase the power processing of WECS to support the network demand. Based on the relevance of this issue, this paper presents a performance comparison of a Double Fed Induction Generator(DFIG)-based WECS employing three topologies of back-toback converters: two-level voltage source converter topology (2L-VSC), neutral point clamped (NPC) and modular multilevel converter (MMC). Simulation results present DFIG currents, voltages, torque, speed and the total harmonic distortion (THD), highlighting the performance improvement employing multilevel topologies and the impacts of using each topology.
