“…It makes following control possible through a series of strategies such as output power regulation by adjustment of pitch angles or start-stop procedure of wind turbines. Similar to conventional units, the performance of the wind turbines control can be evaluated quantitatively by regulating rate and response time (Qiao, et al, 2009, Hansena, et al, 2006, Lubosny, et al, 2007.…”

As large-scale wind power has been and will be integrated into power grid, traditional Active Power Dispatch and Control (APDC) system has encountered new challenges. In this paper, the active power dispatch mode of interconnected power grids which is suitable for the large-scale integration of wind power is analyzed firstly. Secondly, it is pointed out that traditional decentralized balance control mode of active power in provincial power grids would not withstand the impact of the large-scale wind power fluctuation. Then, a centralized control mode is proposed in the paper to reallocate all of the generation resources in a wider power grid. Thirdly, the characteristics of the proposed centralized control mode are analyzed from the following aspects: ways of active power balance, mainbodies of active power control, methods of resource allocation, inter-provincial power exchange, security constraints, and data communications. Finally, considering present dispatch system and technical basis in China, a solution is proposed for the active power control for China interconnected power grids. The aim of the proposed solution is to achieve the centralized control mode, and the hierarchical coordination control mode is the transition between present system and the final system.

“…The ESS type selection for the wind farm is dependent on the control purposes [4]. Fast and short (or medium) term ESS can be used for power quality improvement and frequency control, while slow and long term ESS is more suitable for economic dispatch [5]. In this paper, the fast and short-term ESS unit, such as Battery, Super-capacitor, etc., is utilized in a wind farm for its fast response and the real time operation control purpose of the wind farm.…”

“…In order to reduce a negative impact of the output power fluctuation from the wind farms, the wind output power should be smoothened before delivering into the grid [6,7]. Minimization of the output power fluctuation can be realized by either controllers without additional apparatus or utilization of additional devices.…”

“…However, this control strategy affects high stresses on the turbine blades [7]. Another method to filter out the fluctuated output power is to use the external energy storage systems such as batteries, ultracapacitors, flywheels, etc [6,11,12]. With these external devices, the optimal wind energy is captured by the maximum power point tracking (MPPT) control.…”

-This paper proposes a novel strategy for attenuating the output power fluctuation of the wind farm (WF) in a range of tens of seconds delivered to the grid, where the kinetic energy caused by the large inertia of the wind turbine systems is utilized. A control scheme of the two-level structure is applied to control the wind farm, which consists of a supervisory control of the wind farm and individual wind turbine controls. The supervisory control generates the output power reference of the wind farm, which is filtered out from the available power extracted from the wind by a low-pass filter (LPF). A lead-lag compensator is used for compensating for the phase delay of the output power reference compared with the available power. By this control strategy, when the reference power is lower than the maximum available power, some of individual wind turbines are operated in the storing mode of the kinetic energy by increasing the turbine speeds. Then, these individual wind turbines release the kinetic power by reducing the turbine speed, when the power command is higher than the available power. In addition, the pitch angle control systems of the wind turbines are also employed to limit the turbine speed not higher than the limitation value during the storing mode of kinetic energy. For coordinating the de-rated operation of the WT and the storing or releasing modes of the kinetic energy, the output power fluctuations are reduced by about 20%. The PSCAD/EMTDC simulations have been carried out for a 10-MW wind farm equipped with the permanent-magnet synchronous generator (PMSG) to verify the validity of the proposed method.
