A new control problem called Disturbance Tracking Control (DTC), which arises in active control of variable speed horizontal axis wind turbines for electric power generation, was developed previously. Feedback control of a linear plant, which is persistently disturbed, must cause the plant output to track a linear function of the disturbance. This control theory is related to Tip Speed Ratio Tr...

– In this paper, the authors propose a scheme to react to grid faults. This is based on block control technique using sliding modes. For normal operation the electric torque and the reactive power are controlled; when the fault is incepted the electric torque and the stator current are controlled. The wind turbine is emulated by a DC motor, which is controlled using a discrete time block contro...

Nowadays, power systems, energy generation by wind has been very important. Noting that the production of electrical energy by wind turbines on site is depend on to several factors (such as wind speed and profile site for the turbines, especially off the wind input speed, wind rated speed and wind output speed disconnect) is dependent. On the other hand, there are several different types of tur...

Harnessing wind energy is one of the pressing challenges of our time. The scale, complexity, and robustness of wind power systems present compelling cyber-physical system design issues. In response to these emerging challenges, Purdue has initiated strategic partnerships for infrastructure development. Working with the US Department of Energy, Purdue is developing physical infrastructure for an...

The coherence between single bottom pressure .4 barotropic velocity records collected in the North •c during BEM• and air pressure, wind stress, and wind stress cuff derived from FNOC products are examined •ov• the 2-'00-1 day period band. Strong coherence between the bottom pressure and all atmospheric variables is seen, with nonlocal coherence (maximum up to 1000 km to the southeast) dominati...

Wind and solar power generation differ from conventional power generation because of the variable and uncertain nature of their power output. This can have significant impacts on grid operations. Short-term forecasting of wind and solar power generation is uniquely helpful for planning the balance of supply and demand in the electric power system because it allows for a reduction in the uncerta...

To reduce greenhouse gas emissions, ports around the world are considering using electric cargo handling equipment. To assess the benefits of the strategy, this study provides a comparative life-cycle assessment between diesel and electric yard tractors in a case study of the Port of Los Angeles. Results indicate a significant reduction in life-cycle emissions as the port shifts to electric veh...

In the recent years, due to the increase in the average temperature and environmental pollution and also the demand for energy, finding new resources for energy generation has been a big challenge for the governments. Among the various renewable energy resources, the energy derived from the wind farms has absorbed a great deal of attention. Due to the increase in the power generated by the wind...

Demand response Allows the management of customer consumption of electricity in response to supply conditions. Distributed generation Electric energy that is distributed to the grid from many decentralized locations, such as from wind farms and solar panel installations. Distribution grid The part of the grid dedicated to delivering electric energy directly to residential, commercial, and indus...
