Inertia Support Strategies using Wind Turbines for Low-Inertia Power System with High Penetration of Wind Power

In contrast to traditional synchronous generators, variable speed wind turbines (VSWTs) usually do not provide
inertia response to the power system in case of power imbalance. Thus, in a power system with high penetration
of wind power, there may be a high risk of lack of inertia response in the system. This may lead to frequency
instability or blackout when the power system is subject to a large disturbance.

The aim of this project is first to evaluate the inertia available from VSWTs. Then, the risk of low inertia is
estimated using a probabilistic approach in a wind dominant power system. Two solutions to provide additional
inertia response and to reduce the risk of low system inertia are evaluated.

Finally, the economic value to provide such an inertia response will be evaluated based on a
cost/benefit analysis.
