“…Nowadays, the high penetration of wind turbines on the power systems leads to numerous difficulties in its frequency control [20]. In order to allow flexible and stable operating scenarios with high penetrations of wind power systems, wind generation systems must contribute in power system frequency controlling and supporting.…”

Keywords:Standalone MG MG frequency regulation Inertia and frequency droop DFIG inertia Pitch angle power reserve DFIG reactive power capability a b s t r a c t This paper proposes two controllers for employing part of variable speed wind generation systems kinetic energy in supporting the standalone MG frequency. The first controller acts similar to the frequency droop control, while the second controller emulates both the inertia response and the frequency droop control simultaneously. The MG frequency dropped only to 49.9 Hz with employing the proposed controllers compared with 49.68 Hz without employing the proposed controllers. Also, the injected active power from the storage device dropped from 20 kW to only 3 kW after employing the proposed controllers. In addition, the reactive power capability of the Double Fed Induction Generator (DFIG) wind generation system has been employed to maintain the standalone MG bus voltage at acceptable level. If there are fixed speed wind generation systems in the standalone MG, this paper proposed using the pitch angle controller to employ a suitable wind turbine power reserve in MG frequency supporting during the standalone mode. Results proved the effectiveness of the proposed controllers in improvement the MG overall performance during and subsequent the islanding occurrence.

“…This inherent relation is not as obvious when dealing with wind turbine generators due to the electromechanical characteristics of the currently prevailing variable speed technologies, whose turbine speed is decoupled from the grid frequency [6]. The inertia contribution of wind turbines is much less than that of conventional power plants [6][7][8]. Actually, some variable speed wind turbines use back-to-back power electronic converters, which create an electrical decoupling between the machine and the grid, leading to an even lower participation of wind generation to the system stored kinetic energy.…”

Abstract:In power systems with high wind energy penetration, the conjunction of wind power fluctuations and power system inertia reduction can lead to large frequency excursions, where the operating reserves of conventional power generation may be insufficient to restore the power balance. With the aim of evaluating the demand-side contribution to frequency control, a complete process to determine critical wind oscillations in power systems with high wind penetration is discussed and described in this paper. This process implies thousands of wind power series simulations, which have been carried out through a validated offshore wind farm model. A large number of different conditions have been taken into account, such as frequency dead bands, the percentages of controllable demand and seasonal factor influence on controllable loads. Relevant results and statistics are also included in the paper.

“…The concept of releasing the kinetic energy of a WPGS when the frequency of the power system is reduced in order to prevent the reduction of system inertia is presented [1]. The experimental results of a doubly fed induction generator (DFIG)-based wind turbine using converters [2], modeling of variable-speed wind turbine concepts in power system dynamic simulations [3], and impact assessment of high penetration of wind energy to the Irish network [4] are also available in literature. Frequency regulation and inertial support is also discussed in Refs.…”
