The design of an advanced controller for wind turbine load mitigation is presented. The controller is based on Nonlinear Dynamic Inversion control methods combined with Pseudo Control Hedging to account for the actuator limits and a two degree of freedom control system for the collective pitch control of the rotor blades. The controller uses wind speed measurement information to adjust to wind ...

The work under this Task developed control methodologies and designs that address the problem of maintaining grid electromechanical stability in light of increasing percentage of production from power-electronically coupled renewable resources, such as wind. The challenge in maintaining stable frequency control can arise as synchronous generators, the traditional grid-stabilizing mechanisms, ar...

Renewable energy now-a-days is playing vital role in energy demand market and solar and wind are most wanted renewable energy resources to support the enormous power demand across the globe. Due to insufficient wind for more than half of the year, wind turbines are not capable of meeting the power demand. Hence, solar is treated as the main energy resource among all the renewable energy resourc...

Wind power is sustainable, renewable and clean energy. There are abundant wind resources in Yunnan province, China. In recent years, wind power integration has developed rapidly in Yunnan province. With the first batch of the wind farm being built and a part of them going into production in Yunnan, the wind power resources will be large-scale developed and utilized in the future. Based on the w...

An extensive literature on climate change modeling points to future changes in wind climates. Some areas are projected to gain wind resources, while others are projected to lose wind resources. Oklahoma is presently wind rich with this resource extensively exploited for power generation. Our work examined the wind power implications under the IPCC’s A2 scenario for the decades 2040–2049, 2050–2...

CFD (Computational Fluid Dynamics) simulation is the main research method for assessing the wind environment around building complexes. Recent research showed the importance of turbulence models used in simulation and different turbulence models were developed to improve the precision of CFD simulation results. In this paper, a comparison of different turbulence models in simulating wind enviro...

Now a day‟s electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non-conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. Renewable ener...
