NEW TRENDS IN WIND ENERGY MODELING AND WIND TURBINE CONTROL

Energy planning through optimization techniques is not a new concept, although different new models have been proposed and used over the last 30 years. Environmental concern over the use of conventional sources has reached an alarming stage, thus alternatives sources is imminent. Renewable sources such as wind have gain popularity and demand over the last decade. Renewable sources of electrical energy, which have been lately promoted, are causing problems in distribution and transmission operation networks globally on-shore wind power has seen considerable growth in all grid systems. In the coming decade off-shore wind power is also expected to expand rapidly. Wind power is variable and intermittent over various time scales because it is weather dependent. Therefore wind power integration into traditional grids needs additional power system and electricity market planning and management for system balancing. This extra system balancing means that there is additional system costs associated with wind power assimilation. In this paper, wind energy is reviewed and opened for further discussion. Wind economy, the energy climate relations, wind turbine technology, wind industry, wind control for the wind turbine applications and the current status of installed wind energy capacity all over the world reviewed critically with further enhancements and new research trend direction suggestions. This paper deals with the modeling of Doubly Fed induction Generator (DFIG) cooperating with wind turbine. The wind turbine and the DFIG models are presented step by step. Overall control system of the DFIG is modeled in details in program ATP-EMTP.
