“…This controller will react to the rate of change of frequency. If for instance, the frequency suddenly drops, the controller is activated and delivers an additional power reference value to the converter of the DFIG [12]. This additional power output is a function of the frequency:…”

Abstract-Increasing wind power penetration in power systems has resulted in an urgent need for the assessment of their impact on grid security. Besides the participation in voltage control, there also exists a growing interest in the delivering of other ancillary services like power-frequency control. This paper investigates further the technical feasibility of delivering frequency support with wind turbines in a small power system. Different control mechanisms are elaborated in Matlab/Simulink to deliver frequency support in the case where the turbines have a power reserve available and in the case where they are operating at maximum available power. Also the influence of the generation mix is examined. Results reveal that the displacement of conventional generation with wind power results in a deterioration of the frequency response. However, due to the implementation of the different control mechanisms presented in this paper for delivering inertial response and primary control, the frequency stability is improved.

“…Renewable energy sources are characterized by their stochastic, intermittent generation patterns and by their power electronic interface with the grid. Mechanical dynamics of converter connected generation are completely decoupled from the grid [1,2]. The replacement of conventional synchronous generation with converter connected generation reduces system inertia and primary frequency response of the system [3][4][5].…”

Abstract-This paper presents a framework to analyze the impact of different penetration levels of renewable generation sources (RES) and consequent reduction in inertia on grid frequency. The developed methodology is demonstrated using three operating conditions of the network. For each operating condition, the decrease in the network loading is balanced by disconnecting a part of synchronous generation. To establish the critical penetration levels of renewables and inertia limits for the grid frequency, the uncertainty of loads, intermittent and stochastic patterns of RES generation around each operating condition are simulated. The results clearly identify the critical penetration levels of RES and reduction in inertia limits of the system for frequency stability. In addition, the performed analysis quantifies the effect of primary frequency response and reduction in inertia on frequency nadir. The proposed framework is applied to the modified 16 machine and 68 bus network.

“…This is due to use of power electronic converters [7], for instance back-to-back Voltage Source Converters (VSC), isolating the wind turbines from the power system and making them insensitive to any change in the system frequency and consequently unable to provide any inertial response [8]- [10]. Furthermore, to get the maximum power from wind power plants Maximum Power Point Tracking (MPPT) algorithm is used, so that wind turbines can hardly contribute to the frequency control [11]- [12].…”

-The use of high power electronics in the large scale integration of wind power in the transmission and distribution systems can affect the system inertia response and the ability to recover frequency stability after large disturbances. Different approaches have been presented to show the system dynamic behaviour, and to quantify the wind power impact on the system inertial and frequency response. This paper gives a short overview of studies performed regarding the system inertia issues under high penetrations of wind power. Also, it presents the results of a case study to show how the system inertia can be affected by high penetrations of wind power.
