This paper proposes an optimal control strategy for participation of wind farms (WFs) in primary frequency control. In this strategy, we exploit wake interaction in a WF to maximise the total kinetic energy (KE) of the wind turbines' (WTs') rotating masses in the WF, and optimally deploy this KE after a frequency event to reduce the frequency nadir, by controlling the rate of change of the rotor speed...
Wind generation is the most increasing resource in the renewable energy. Now a days, the wind power has a large installed output power capacity in the world among the renewable energy sources. The wind power integration into power system grids has some effect on power system issues as transmission congestion, optimum power flow, system stability, power quality, system economics and load dispatch....
With the fast development of wind power, the techniques related to its grid integration and control have been researched all over the world. In which, active power control of wind farm is one of the most important techniques. However, current methods are not good to satisfy the relevant requirements. For the problem, an optimal active power control method of wind farm using the information of ultra-short-term...
A novel control method for tip speed ratios of the series connected wind turbines in a wind farm by controlling the field currents of the wind generators is proposed. It is confirmed that good agreements between experimental and simulation results are obtained, showing the usefulness of the proposed method of the simulation model. Also, it is shown that reactive power of the wind generators of this...
Wind power generation is becoming increasingly common in the portfolio mix of many utilities around the world. Wind turbines are presently available up to 5MW. Smaller turbines may be installed for individual customers and connected to the grid at the distribution level, and larger units are typically combined in a wind “farms” connected to bulk power systems at the transmission level. Turbines ranging...
Battery energy storage system (BESS) is to be incorporated in a wind farm to achieve constant power dispatch. The design of the BESS is based on the forecasted wind speed, and the technique assumes the distribution of the error between the forecasted and actual wind speeds is Gaussian. It is then shown that although the error between the predicted and actual wind powers can be evaluated, it is non-Gaussian...
With the development of wind power, the inherent characteristics of randomness and uncertainty of wind energy would have an impressive effect on power system frequency, it is necessary for wind farm to participate in frequency regulating in order to share the burden with the frequency-regulating power plants, and to improve power system stability. Two operation modes of the wind farm are proposed...
An efficient hybrid distributed genetic algorithm is proposed to determine the proper number and locations of wind turbines in large wind farms. The objective of this optimal process is to find a solution that maximizes the annual profit obtained from a wind farm. It is well-known that genetic algorithms are good for global searches, but are weak for local searches. To improve the performance of finding...
During recent years, the size of individual wind turbines has grown closer to 10 MW, and the size of wind power plants has increased significantly to 300 MW or more. This growing size of wind power generation requires that careful evaluation of transient stability of the overall grid should be undertaken. This paper attempts to investigate the impact of wind power plant penetration on the transient...
Wind energy has taken off into a new peak in terms of its popularity among other new generation technologies. The socio-economic and environmental benefits impact the general population. A low cost of energy along with grid compatibility can be achieved due to mass production technology, power electronics advancement, and intelligent controllability. This paper attempts to shed the light on many aspects...
In order to research the wind power technology in the environment far away wind farm, this paper proposed a design and realization wind power generation simulating and experimental system based on ARM and DSP. It includes wind speed simulating system, wind turbine simulating system, power generation system, monitoring system and controller. In the system, simulates actual wind using statistical model...
With the increased use of wind energy for the power generation several TSO have increasing difficulties for congestion forecasting due to the unpredictable nature of the energy source. An actual method used to deal with days-ahead congestion planning is based on an order of disconnection of the generation of the type ldquolast generation installed, first generation limitedrdquo. This paper proposes...
As the development of renewable energy has become a national strategy for reducing CO2 emissions, the level of penetration of wind generation has increased rapidly in recent years in many countries. The output of wind generation is variable especially during the high wind velocity periods. The mismatch of wind farm output will also lead output fluctuation of other generators. These small changes of...
A new interconnecting method for a cluster of wind turbine/generators is proposed, and some examples of the basic characteristics of the integrated system are shown. This method can be achieved with wind turbine generating system using a shaft generator system. A group of wind turbine-generators can be interconnected easily with the proposed method, and high reliability and electric output power with...
Wind energy will continue to grow at a rapid pace and will provide an increasingly large portion of the total electricity generation. To achieve its full potential, the industry needs adequate wind-turbine generator (WTG) dynamic models to determine the impact of adding wind generation, and establish how the system needs to be upgraded.For the most part, WTG manufacturers have sponsored the development...
There is a national targeted amount of 20.000 MW of installed wind power in the Spanish Electrical System by 2010, the new Infrastructures Program -2016 horizon-, to be issued in the next months, appoints to a new 29.000 MW target for that period, and there are even more ambitious objectives for the next decade. This amount of installed power, compared with a load peak around 43700 MW and taking into...
