“…The effects of fluctuating wind power on system regulation and stability are important issues. Large offshore wind farms may inject significant power fluctuations into power systems [9], and such power fluctuations may affect neighbouring power systems, if it is not appropriately dealt with. For example, the offshore wind farm Horns Rev A in Western Denmark produces more intense active power fluctuations than the aggregated wind power produced by land based wind farms in the western Danish power system and shows frequent active power fluctuations within periods of tens of minutes, the power gradients reach 15 MW per minute, thus the 160 MW wind farm have the output power change between zero and the rated power in 10-15 min [10].…”

In recent years, wind power is experiencing a rapid growth, and large-scale wind turbines/wind farms have been developed and connected to power systems. However, the traditional power system generation units are centralized located synchronous generators with different characteristics compared with wind turbines. This paper presents an overview of the issues about integrating largescale wind power plants into modern power systems. Firstly, grid codes are introduced. Then, the main technical problems and challenges are presented. Finally, some possible technical solutions are discussed.

“…In fact, the power supplied by wind turbine behaves randomly followed the wind conditions, and probabilistic wind farm generation model seems much more appropriate for the PLF calculation [5]- [8]. A probabilistic model for the active power produced and the reactive power absorbed by wind turbines equipped with induction generators was developed in [5].…”

This paper presents a probabilistic wind farm model for probabilistic load flow (PLF) calculation applied to gridconnected induction wind power system. In the model, the real power injected and reactive power absorbed by the wind turbine are described as the function of the voltage magnitude, the slip of the induction machine and circuit parameters of the wind turbines. Then, the slip of induction wind turbine generator is introduced as the new correction value in the PLF equations, and thus the PLF equations can be solved by performing a unified iteration for the original state variables and the slip. Using the Newton-Raphson (NR) algorithm, the method retains the quadratic convergence of the NR algorithm. Finally, PLF is performed on the IEEE test system, and the impact of uncertain wind power on the system voltage is analyzed. The results show the effectiveness of the proposed model.Index Terms-probabilistic wind farm model, probabilistic load flow, uncertainty, Weibull probability density function.

Distribution power networks are accommodating more and more generation and most of them are based on renewable sources, like wind power. Then, this new generation, generally known as distributed generation (DG), has a stochastic power production that affects technically the network in different ways. However, availability and power quality must be kept within standard limits. Deterministic approach can not cope with this issue and a probabilistic assessment is needed. Wind power has a high level of integration around the world. Then, its impact of voltage profile in a distribution network is analyzed.
