And Performance

As large-scale wind farms are connected to the grid, a single type compensator cannot meet the demand. STATCOM has ability of rapid reaction and harmonics suppression, SVC can compensate large capacity reactive power. In this study, a compensator, which is able to coordinate Static Var System (SVS) with STATCOM is proposed. Large-scale wind power integration is simulated respectively with the compensator of STATCOM alone and coordinated compensator of SVS and STATCOM by DIgSILENT/Powerfactory15.0. Simulations results clearly verify that the compensator of SVS and STATCOM improves transient stability and performance of the photovoltaic systems.

As an increasing proportion of wind power in power grid, reactive power problem has become the most important problems in wind power integration. But as a result of wind power is a kind of intermittent energy sources, and put it into use in a large scale only just beginning. Many urgent problems which affect on system stability need to be resolved, such as voltage stability, reactive power compensation. This paper discussed the problems which around the reactive power compensation and angle stability issues while wind power integration. The reactive power compensation device named STATCOM instead of traditional capacitance. Establish the mathematical model of the Doubly-Fed Induction Generator (DFIG) and Static Synchronous Compensator (STATCOM) [3]. In order to meet the wind farm can transport reactive power quickly and continuously after fault. Establish the control strategy of DFIG combined with STATCOM [1]. Using the software MATLAB to simulate the wind power grid model and control system, verifies the rightness and effectiveness of model and STATCOM reactive power compensation effect for wind power integration.

The Impact

Renewable Energy especially wind energy integration has attained profound growth across the worldwide power system. Wind energy integration at large scale comes up with the challenge on voltages and reactive power management at power system level. The research work presented in this paper has analyzed the impact of wind energy on reactive power reserve with special reference to Hebei Southern Power System. The maximum wind power integration capacity is calculated, and the effect of increasing wind power integration on voltage profiles is studied. Possible controls from system sides and its effects on wind power integration are explored. Study shows that with the increase of the wind power integration capacity, the intermittency and variation will bring more serious problems to the system frequency regulation, reserve service and voltage control. These problems also become the limiting factors for further increase of large-scale wind power integration. In order to make a better use of wind power resources in Heibei province and maintain system safety at the same time, further research should be performed on exploring the reactive and active power regulation and control of the wind farm and the methods to decrease the variability of wind farm outputs.

Doubly Fed

The technology of large-scale wind power connected to grid is a key technology in the application of wind power. However, the large-scale wind power will cause the negative effect on the voltage of grid. So, the regulation of reactive power is necessary, which can stabilize the voltage level of the grid. The doubly-fed induction generators (DFIG) themselves own the ability of providing reactive power. Considering the reactive power demand when the power grid is operating, and then rationally allocating static and dynamic reactive power compensation equipment, the operational efficiency can be improved. The particle analyzes the reactive power limit of DFIG, considering the limit of stator and rotor. In this way, the reactive power compensation capacity of DFIG is used first, the use of reactive power compensation equipments are greatly reduced, so the economy of the wind farm is obviously improved.

As a kind of renewable clean energy, the constant access of wind power to power grids is bound to have a great impact on the power system. Based on the grid structure in Fuxin, this paper will state the difficulty of peak regulation and the matter of wasting wind power caused by the large-scale wind power integration and put forward some reasonable methods for using the wasting wind power in the heating in winter.
