“…The effect and intention of such supervisory controllers on park level is that the combined responses of the wind turbines (WT), evaluated at the interface between the WPP and the power system, are comparable to other power plants. The ability of WPPs to deliver active power reserves are treated in a number of publications [2]- [5], as well as voltage and reactive power control [6], [7]. In some countries, for instance Denmark, WPPs are already applied for ancillary services, e.g.…”

Abstract-Small-signal stability analysis of power system oscillations is a well established field within power system analysis, but not much attention has yet been paid to systems with a high penetration of wind turbines and with large wind power plants. In this paper an analysis is presented which assess the impact of full-load converter interfaced wind turbines on power system small-signal stability. The study is based on a 7 generator network with lightly damped inter-area modes. A detailed wind turbine model with all grid relevant control functions is used in the study.

“…The dynamic performance studies of the wind turbines are mainly dedicated to DFIG-based WTs and can be divided into several categories, such as: impact of WT on power system dynamics [5][6], grid fault response of WT [7][8], fault ride-through capability of WT [9][10], participation of WT in grid frequency stability [11][12], investigation the WT drive train dynamics [13][14], and WT dynamic response under wind speed and aerodynamic power fluctuation [15][16].…”

“…Additional frequency regulation methods to maintain the stability have been analysed to reduce the frequency variability and ROCOF. In [3], the frequency response of a wind-based power system with low inertia was regulated using a droop controller. The work in [6] utilised two additional frequency control loops within wind turbines to improve the frequency stability.…”

This paper analyses and compares different methodologies for supporting system frequency in low inertia power systems using HVDC interconnectors. Reduced system inertia, caused by the massive integration of converter-interfaced renewables and the displacement of conventional synchronous generation, can result in high values of rate of change of frequency (ROCOF), increasing the risk of frequency stability problems. In this paper, HVDC interconnections are analysed to determine their capability to provide support to the frequency stability between the Great British (GB) power system and the Continental Europe (CE) power system. Different frequency support control schemes (including droop control and the exchange of Frequency Control Reserves) are modelled and compared for a variety of cases. HVDC interconnector constraints including maximum power ramp rates and available capacity for frequency support have been derived by analysing historical operational data and incorporated into the analysis. Probabilistic uncertainty analysis considering variations in system inertia and the availability of interconnector capacity for frequency support has been performed. Studies are performed on a simplified frequency-based model of the future GB power system. The findings illustrate that droop control provides the best frequency support mechanism.
