Despite their steep drops this year, oil and gas prices historically have been subject to wild fluctuations and spikes that worry even the calmest of planners. With RES penetration on an upward trajectory, managing grid stability becomes a top priority with three significant challenges: The integration of a large share of RES in the energy mix means potentially significant power injection during peak load hours, which requires more system flexibility to balance energy supply and demand. • King Island isolated power system. The challenge to maintain grid stability differs significantly by country and region. The reason for such a contrasting situation is that the scope of the challenge facing each country depends strongly on context. And finally, improving the fault ride-through of wind generation could be an additional puzzle piece to the inertia reduction challenge. A good example of such a transformation is the German power system, where renewable energy sources (RESs) are, The problem of defining and classifying power system stability has been addressed by several previous CIGRE and IEEE Task Force reports. As wind energy systems utilize different generator technologies from the one utilized in the conventional power plants, the steady-state, transient and small-signal dynamics, as well as, power system stability will thus be significantly affected. .
