“…The calculation of optimal power flow is used to perfom power system, using voltage and power measurement , it can solve the problem of the active and reactive energy produced by wind farm [28], in fact the classical method based on load flow calculation does not take into account the limits of reactive power in lines and power plants, these constraints can however be programmed in power flow solvers ,in fact the reactive power capability of DFIG can play the role of reactive power compensation devices if the operating system limits the outpout of the wind farms [29]. In our case, we assumed that an independent producer is managing the 50% penetration rate of the wind farm.…”

Wind farm has been growing in recent years due to its very competitive electricity production cost. Wind generators have gone from a few kilowatts to megawatts. However, the participation of the wind turbine in the stability of the electricity grid is a critical point to check, knowing that the electricity grid is meshed, any change in active and reactive flux at the network level affects its stability. With a rate of 50% wind turbine penetration into the electricity grid, the stability of the rotor angle is a dynamic phenomenon which is only visible by the variation of the active energy. The purpose of this journal is to verify the impact of wind turbine integration on an electrical grid, by exploiting the relationship between the reactive energy produced by the Doubly Fed Induction Generator equipping most wind energy systems, and the stability of the rotor angle of the synchronous generators equipping the conventional power plants in the electrical system.

A new topology was recently developed to drive generators, aiming to avoid power electronic devices directly connected to the grid, and making possible the hybridization of the wind power with other sources. The system is composed by an induction machine with rotor in squirrel cage, and a rotating armature endowed with a three-phase winding that may be fed by a secondary source. The previous purpose was to convert a variable velocity imposed by the wind turbine to the armature in a constant velocity to be developed by the cage rotor, driving a shaft of synchronous generator. This article proposes the use of an induction generator instead of a synchronous one in order to explore the maximum available wind energy (MPPT). The simulation results show that the proposed topology is viable and supports both variations in wind speed and disturbances in power grid.

“…There is also a significant difference between the hardware and software environment, making the WECS more unmanageable and uncontrollable. Wind power generation control systems could be deployed in various heterogeneous controller hardware, including: (1) controllers designed and developed by companies specialized in wind power industry, like the series of WP3000 and WP4000 of MITA [28]; (2) high-performance PLC and industrial personal computer (IPC) [29,30]; and (3) the embedded system hardware platform based on a micro-processor e.g. DSP, ARM, or FPGA [31,32].…”

The parallel system is a kind of scientific research method based on an artificial system and computational experiments, which can not only reflect the dynamic process of the real system but also optimize its control process in real time. Given the rapid development of wind energy technology, how to shorten the development and deployment cycle and decrease the programming difficulties of wind energy conversion system (WECS) are major issues for improving the utilization of this form of energy. In this paper, the Data Engine is used as a computing environment to form a parallel WECS for studying the engineering application of WECS. With the support of the programming methods of graphical component configurations, visualization technology and dynamic reconfiguration technology, a maximum power point tracking (MPPT) computing experiment of the parallel WECS is carried out. After comparing with MATLAB simulation results, the parallel WECS is verified as having good performance. The Data Engine is an ideal computing unit for modeling and computation of the parallel system and can establish a parallel relationship between the artificial system and the real system so as to achieve the optimal control of WECS.
