“…Generally, as foreshadowed by other studies [4] - [7], [9], [14], [15] the worst event that can happen is the loss of the largest generator or the HYDC interconnector preceded by an AC fault.…”

“…Inertia in a power system is provided by synchronous ma chines. Wind turbines have not traditionally provided inertia (Although there have been some indications that future gen erations of wind turbines may also have this feature [7], this feature is not useful if the active power output from the wind farm has not recovered.). To increase the inertia of the system, extra synchronous plant must be brought on-line.…”

“…It is already well known that wind generation can have an adverse effect on system stability, particularly in the areas of frequency control [4] - [7]. With the outlook of increased wind penetration in Tasmania a recent focus of effort has been to determine the amount of wind generation that can be sustained before these system stability issues become unmanageable.…”

Large-scale integration of wind into power grids can have significant impact on the system stability. This paper presents the Rate Of Change Of Frequency (RoCoF) metric to determine limitations of the system with high levels of wind pene tration. The metric takes into account the system inertia, wind turbine response, and the size of contingencies. The metric is then applied to the Tasmanian power system -a small predominantly hydro power system with a potentially large-scale penetration of wind. The simulation studies are carried out using PSS/E. Case studies are performed with critical contingencies such as the loss of synchronous generation, loss of wind generation and loss of the HVDC interconnector, and their impacts are discussed.

“…Several methods for achieving this have been proposed and demonstrated [1], [2], [3], [4], [5], [6]. Although there are subtle differences each of these methods rely on measuring the grid frequency for adjusting the active Support power/torque reference of the wind farms to counteract the variations in measured frequency.…”

Abstract-A communication-less scheme that allows remote offshore wind farms connected through HVDC links to participate in primary frequency control and contribute to system inertia is discussed in this paper. As a HVDC link decouples the offshore system from the onshore side, real-time communication of onshore frequency is normally required for the primary frequency control loop of the wind farms. Dependance on remote communication which could be unreliable at times is a problem. To obviate the need for communication, appropriate droop control on the offshore and onshore converters is used in this paper to translate the variation in onshore frequency to an equivalent variation on the offshore end. Thus the need for communicating onshore frequency to the offshore side is obviated which ensures reliable operation. Such a communication-less scheme is compared against the conventional approach involving remote communication of onshore grid frequency to the wind farm site. Along side physical and analytical justification, a case study is presented to demonstrate that the communication-less scheme performs similar to the conventional one in terms of reducing grid frequency variations.

“…Reference [1] alludes to centralized control systems that can provide ancillary services that are required by transmission providers. Reference [27] describes the features that are available with the control systems from one manufacturer. In addition to other features, these control systems can monitor voltage and current at the substation and adjust the reactive various power resources (including the WTGs) to meet a desired voltage set point.…”
