“…WTGs having the same incoming wind speed are aggregated in [11], [20]. Further improvement is proposed [21] in which wind power curve is divided into many sections and the WTGs fall in one section are aggregated. In [22], post fault voltage profile in the collector network is used to determine number of aggregate machines.…”

“…Wind energy systems are under developing toward higher capacity and offshore location. [1] Generally, in order to obtain higher energy production and optimize the costs regarding installation and interconnection, many single wind turbines are organized into groupsso called wind farm. During the wind farm planning process an important task is to minimize the area utilized by the planned wind farm.…”

A wind farm is a collection of a few tens or a few hundreds of wind turbine generator installed in close vicinity. There is a need for further research to examine the performance of wind farm and wake models in difficult environments. This paper deals with the modelling of the wake effect in wind farms using real time digital simulator. There are many different models to analyse the wake effect. Jensen model is one of the widely used wake models at the moment. The model is simpler and requires a short time for calculations. Power loss of the modelled wind farm with the wake effect is analysed under the effects of wind direction and the wind speed time delay. The modelling of a wind farm for wake effect simulation is described and some exemplary simulations are also performed to show the influence of wake effect.

“…Therefore, it's feasible to establish an equivalent model to simulate the operation of a wind farm group. That is to say, regard the power collection point as a unit and replace the wind farms of the same power collection point by an equivalent wind turbine, which specifically comes down to two steps: firstly, replace m wind turbines of the same wind farm by one equivalent wind turbine adopting the capacity weighted method [37]. The calculation of the parameters of the equivalent wind turbine is shown in Equation (1): …”

Abstract:For the interconnected power system with large-scale wind power, the problem of the small signal stability has become the bottleneck of restricting the sending-out of wind power as well as the security and stability of the whole power system. Around this issue, this paper establishes a small signal stability region boundary model of the interconnected power system with large-scale wind power based on catastrophe theory, providing a new method for analyzing the small signal stability. Firstly, we analyzed the typical characteristics and the mathematic model of the interconnected power system with wind power and pointed out that conventional methods can't directly identify the topological properties of small signal stability region boundaries. For this problem, adopting catastrophe theory, we established a small signal stability region boundary model of the interconnected power system with large-scale wind power in two-dimensional power injection space and extended it to multiple dimensions to obtain the boundary model in multidimensional power injection space. Thirdly, we analyzed qualitatively the topological property's changes of the small signal stability region boundary caused by large-scale wind power integration. Finally, we built simulation models by DIgSILENT/PowerFactory software and the final simulation results verified the correctness and effectiveness of the proposed model.
